Koh Samui has a lot more to offer than beaches and resorts. If you’re looking for the best things to do in Koh Samui, you can spend your days visiting temples and waterfalls, exploring night markets, training Muay Thai, taking boat trips to nearby islands, or simply enjoying the different beach towns around the island.
I spent two weeks based in Lamai while attending a fitness retreat, which gave me plenty of time to explore beyond the main tourist areas. I visited night markets around the island, trained Muay Thai, watched one of my instructors fight, spent time in Chaweng and Bophut, and made trips to many of Koh Samui’s best-known attractions.
Some of the top things to do in Koh Samui are easy to fit into a few hours, such as visiting Big Buddha, Wat Plai Laem, or Grandfather and Grandmother Rocks. Others, like Ang Thong National Marine Park or a day trip to Koh Tao, are better treated as full-day excursions.
This guide covers the Koh Samui attractions, activities, and places to visit that I think are most worth adding to your trip, along with a few more unusual experiences that helped make my time on the island memorable.

Best Things to Do on Koh Samui
Koh Samui has a mix of beaches, temples, nightlife, outdoor activities, and day trips, so the best things to do really depend on how you like to travel. These are the attractions and experiences I would prioritize, including several that I did during my two weeks on the island.
1. Visit the Big Buddha
The Big Buddha is one of the most recognizable landmarks and popular attractions in Koh Samui. The 12-meter-high golden Buddha sits at Wat Phra Yai, at the top of a wide ceremonial staircase overlooking the surrounding area.
You can walk around the temple grounds, climb the stairs for a closer look at the statue, and spend some time watching the activity around this active Buddhist temple. There are also several small shops and places to eat near the entrance.
Big Buddha is located on the northern side of Koh Samui, not far from the airport, on a small island connected to the main island by a causeway. I wouldn’t call it the most impressive attraction on Koh Samui, but it’s an easy stop and worth seeing, especially since Wat Plai Laem is nearby and the two can easily be visited together.
2. Experience Chaweng Beach and Its Nightlife
Chaweng Beach is the busiest and most social area of Koh Samui, with a long stretch of white sand during the day and the island’s most active nightlife after dark. The beach is lined with resorts, restaurants, beach clubs, and bars, and it’s a good place for swimming, relaxing on the sand, or trying water sports such as jet skiing and parasailing.
If you’re looking for nightlife in Koh Samui, Chaweng is the first place I’d recommend. The atmosphere varies quite a bit depending on where you go, from beach clubs with DJs to large nightclubs and more casual bar areas.
- Chaweng Beach: Most of the beachfront gets quieter later in the evening, but ARKbar Beach Club is one of the exceptions. ARKbar is one of the best-known nightlife spots in Chaweng, with DJs, a younger crowd, and parties that can continue well into the night. Elephant Beach Club can also be lively when it is hosting an event or party.
- Soi Mango: This is the main nightclub area in Chaweng and is named after The Green Mango, a large open-air club that anchors the street. You’ll also find other clubs, smaller bars, and some adult-oriented venues in the surrounding area.
- Soi Reggae: This area has a more casual nightlife scene, with beer bars, pool tables, and venues aimed largely at tourists. Reggae Pub is one of the better-known stops and is popular for live music.
Chaweng is worth visiting even if you are staying somewhere quieter on the island. You can spend the afternoon on Chaweng Beach, have dinner nearby, and then stay into the evening to experience the liveliest nightlife in Koh Samui.
3. Enjoy the Laid-Back Side of Lamai Beach
Lamai Beach is one of the largest and most popular beach areas on Koh Samui, but it feels noticeably more relaxed than Chaweng. The long stretch of sand is good for swimming, sunbathing, walking, or simply spending a quieter day by the water without giving up easy access to restaurants, bars, and other activities.
During my fitness retreat in Lamai, we jogged the length of the beach several mornings, and it became one of my favorite ways to start the day. The beach is long enough that you can cover a good distance, and the mornings are much quieter before the restaurants and beach clubs get busier.
If you want a livelier section during the day, the area around Third Day Beach Club and Red Elephant Beach Club tends to have more activity. Otherwise, there are plenty of quieter stretches where you can simply put down a towel or stop at a beachfront bar for a drink and a chair.
Lamai is also a good base for several other things to do in Koh Samui. Grandfather and Grandmother Rocks are just south of the main beach, and the area has cooking classes, spas, Muay Thai gyms, and several fitness retreats. The Jamaican-themed Rock Bar is another unusual stop near the southern end of Lamai.
At night, Lamai has its own nightlife scene, but it is much smaller and more laid-back than Chaweng. The busiest areas are around Lamai Boxing Stadium and the streets near Billabong Bar, where you’ll find a mix of bars, live entertainment, and casual nightlife.
4. Eat at a Koh Samui Night Market
Visiting a night market is one of the best things to do in Koh Samui if you want to combine local food, shopping, and a lively evening atmosphere. The markets get busy after dark and are popular gathering places for both tourists and locals, with groups moving between food stalls, bars, shops, and live entertainment.
I ate at the two markets in Lamai most often because they were close to my fitness retreat, and I ended up having many dinners there. But I also visited most of the other major night markets around Koh Samui at least once. I don’t think there is one night market you absolutely need to choose over the others. Which one makes the most sense usually depends on where you are staying and which markets are open that evening.
Some of the most popular night markets in Koh Samui include:
- Lamai Night Market: One of the markets I visited most often. You’ll find fruit juices, grilled skewers, seafood, Thai dishes, and several nearby restaurants. There is also a bar with live music at the end of the market. Location
- Lamai Night Plaza: Located beside Lamai Boxing Stadium and the surrounding nightlife area, making it easy to combine dinner at the market with bars or a Muay Thai fight. Location
- Chaweng Night Market: A convenient option if you are staying around Chaweng, located near Central Samui shopping mall. Location
- Fisherman’s Village Night Market: One of the busiest and most tourist-friendly markets on the island, with street food, shopping, and plenty of nearby bars and restaurants in Bophut. Location
- Si Khao Night Market: Located farther from the main tourist areas around Chaweng and Lamai, so it tends to have a more local atmosphere. Location
- Nathon Night Food Market: Near the ferry area on the west side of Koh Samui. Because fewer tourists stay on this side of the island, Nathon had one of the more local-feeling night market experiences I found. Location
If you have several nights on Koh Samui, I’d visit more than one. The markets vary in size and atmosphere, and they are an easy way to try different Thai foods while experiencing one of the island’s most popular evening activities.
5. Walk Around Wat Plai Laem
Wat Plai Laem is one of the most striking temples in Koh Samui and an easy stop to combine with the nearby Big Buddha. The temple complex is best known for its enormous 18-arm statue of Guanyin, the Goddess of Mercy and Compassion, along with a large statue of the Chinese Laughing Buddha.
The architecture blends Thai and Chinese influences, and the complex is built around a lake, which gives it a very different feel from many of the island’s other temples. You can walk across the bridges between the different buildings, explore the shrines, and watch the activity around this still-active place of worship.
Wat Plai Laem is only about a 20-minute walk from Big Buddha, so it makes sense to visit both during the same trip. Just keep in mind that there is not much shade along parts of the walk, and the heat can become pretty intense in the middle of the day.
I walked around quite a bit afterward looking for somewhere to get food and a beer, and that was probably the part I underestimated most. Unless your taxi is waiting nearby or you already know where you are going next, you can end up spending more time walking in the heat than expected.
For that reason, I’d try to visit earlier in the morning or later in the afternoon if possible. Wear comfortable shoes, bring water, and remember that Wat Plai Laem is an active temple, so dress respectfully when walking around the grounds.
If you are looking for cultural attractions or things to see in Koh Samui beyond the beaches, I would put Wat Plai Laem fairly high on the list, especially since you can easily see it and Big Buddha on the same outing.
6. Visit Fisherman’s Village in Bophut
Fisherman’s Village in Bophut is one of my favorite places to visit in Koh Samui in the evening. It feels quite different from the busier streets of Chaweng and Lamai, with old wooden shophouses now filled with restaurants, bars, boutiques, and small shops running along the waterfront.
The main street becomes especially lively after dark, when people come for dinner, drinks, shopping, and a walk along the beach. If you visit when the Fisherman’s Village night market is being held, you’ll also find street food, live music, and vendors selling clothing, souvenirs, and handicrafts. I cover the island’s night markets in more detail above, but this is one of the busiest and most social.
The beach itself is relatively quiet, but several restaurants and bars spill out toward the sand, making Bophut a good place for a relaxed dinner by the water. Coco Tam’s is one of the best-known spots and draws a large crowd for its beachfront fire shows, so I’d get there early if you want a good seat.
For a quieter dinner, I also liked Red Moon, located across the street from the beach. Its menu mixes Thai, French, and Vietnamese influences and was one of the better restaurants I found around Fisherman’s Village.
Even if you are staying elsewhere on the island, Bophut is worth coming to for an evening. Have dinner, walk through Fisherman’s Village, stop for a drink, and catch the fire show or night market if the timing works with your visit.
7. Watch a Muay Thai Fight
Muay Thai is such a visible part of Koh Samui that even if you never step inside a gym, you will probably notice how popular it is. You’ll see training camps around the island, posters advertising upcoming fights, and trucks driving through the streets with loudspeakers promoting fight nights.
We went as a group from my fitness retreat, which made the night even more fun. One of our instructors was fighting that evening, and he is the fighter pictured in the photo I use for this section. After training with him during the week, watching him compete in an actual match gave the experience a much more personal connection.
There are a couple of very different ways to watch Muay Thai in Koh Samui:
- Samui International Muay Thai Stadium: This is the more traditional stadium experience, with scheduled fight cards, bleacher-style seating, and paid admission. It is located around Soi Reggae in Chaweng, so it is easy to combine with a night out in the island’s busiest nightlife area.
- Lamai Boxing Stadium: This has a much more casual atmosphere and sits right in the center of Lamai’s nightlife area. Rather than feeling like a formal arena, the ring is surrounded by bars, and spectators typically watch while having drinks nearby.
If you are already taking Muay Thai classes or staying at a fitness retreat, I would definitely try to see a fight while you are on the island. Even if you are not training yourself, it is one of the more memorable nighttime activities in Koh Samui and gives you a better sense of how important the sport is to everyday life in Thailand.
8. Go on a Fitness Retreat
Fitness is a surprisingly big part of the travel scene in Koh Samui. Around areas such as Lamai, you’ll see traditional gyms, Muay Thai camps, group workouts, runners, yoga classes, and several fitness retreats that attract people who come to the island specifically to train.
I spent two weeks at a fitness retreat in Lamai, so this was a much bigger part of my Koh Samui experience than simply visiting a gym for a workout. The retreats typically combine several workouts each day with group activities, healthy food, recovery sessions, and accommodation, creating something closer to a fitness-focused vacation than a normal gym membership.
You also do not need to arrive in great shape. During my stay, the group included people ranging from their 20s into their 50s and with very different fitness levels. Some came specifically to lose weight or improve their fitness, while others were digital nomads or repeat visitors who simply enjoyed the structure and social side of the retreat.
What Is a Koh Samui Fitness Retreat Like?
Most programs follow a structured daily schedule, but the workouts vary throughout the week. Depending on the retreat, you may have morning runs or hikes, strength training, HIIT, yoga, swimming, boxing, and Muay Thai.
Recovery is also a big part of many programs. Massages, stretching, ice baths, saunas, meditation, and spa visits may be included or offered as optional extras, which becomes particularly welcome after several days of training.
Accommodation is often bundled into the retreat package or arranged at a nearby hotel or villa. I recommend staying with the group if you can. A large part of the experience is social, and sharing workouts, meals, hikes, and downtime makes it much easier to get to know everyone.
Food varies by retreat as well. Some offer structured meal plans focused on healthier eating, while others give you more flexibility. My retreat offered a meal plan, but I chose not to use it. I often ate breakfast or lunch and grabbed smoothies at the on-site cafe, then went out in the evening so I could still explore Koh Samui’s restaurants and night markets.
For travelers who enjoy working out, a fitness retreat is one of the more unique things to do in Koh Samui and can easily become the focus of an entire trip rather than just a single activity.
My top choices for best fitness retreats on Koh Samui are the following:
Lamai Fitness Retreat
Lamai Fitness Retreat is my top choice for a fitness retreat in Koh Samui and where I spent two weeks training. The program is based around a full gym and the adjoining Evolution Muay Thai & Boxing facility, with a schedule that mixes cardio, strength training, Muay Thai, boxing, yoga, open-water swimming, and group hikes.
Mornings might start with a run or hike before moving into Muay Thai, boxing, HIIT, swimming, or yoga. After lunch, there are often additional group activities followed by afternoon strength sessions, so you can make the days as active as you want. The weekly schedule also included access to LUUMA, a spa with an outdoor pool, saunas, and hot and cold plunge pools, which was a welcome recovery day after several days of training.
One of the things I liked most about Lamai Fitness Retreat was the social atmosphere. Many of the people I met had been there before, and several already knew each other from previous visits. The group during my stay ranged from people in their 20s into their 50s and included a wide range of fitness levels. Some had flown to Koh Samui specifically for the retreat, while others were digital nomads spending a longer period on the island.
The location also makes it relatively easy to stay without renting a scooter. The retreat is directly behind the accommodations used by the program, and central Lamai is roughly a 15-minute walk away, which made it easy for me to go out for dinner or visit the night markets in the evening.
I lost about eight pounds during my two weeks here, although what I remember most is how quickly the group became part of the experience. Between the workouts, hikes, meals, and downtime, it felt much more social than simply spending two weeks going to a gym.
Koh Fit
Koh Fit is another popular fitness retreat in Lamai and generally felt larger and busier than Lamai Fitness Retreat. The facility is more modern and gym-focused, with a large weight-training area on the first floor, space for classes upstairs, an on-site cafe, and a 20-meter swimming pool.
The program still attracts a wide range of ages and fitness levels, but the biggest difference I noticed was the style of training. Koh Fit seemed to have more emphasis on strength training and weightlifting, with less focus on Muay Thai and boxing than Lamai Fitness Retreat. Otherwise, the overall structure is similar, with scheduled workouts, group classes, and a social atmosphere built around training.
The main drawback is the location. Koh Fit is farther from the main downtown area of Lamai and from some of the accommodations used by participants, so renting a scooter is much more useful here if you want to explore restaurants, night markets, or the beach in your free time.
I would recommend Koh Fit to travelers who want a more traditional gym and strength-training environment while still having the structure and community of a fitness retreat.
9. Learn Muay Thai
Muay Thai gyms are everywhere on Koh Samui, and training is popular with both short-term visitors and people staying on the island for weeks or months. You do not need any previous experience to try it. Most gyms welcome complete beginners, while also offering more serious training for experienced fighters.
Often called the “art of eight limbs,” Muay Thai uses punches, kicks, knees, and elbows. A typical beginner session may include warm-ups, conditioning, pad work, heavy-bag drills, and basic technique. Depending on the gym and your experience level, you may also do partner drills or sparring.
I trained in Muay Thai as part of my fitness retreat in Lamai, where it was one of the regular activities on the weekly schedule. Even if you are not interested in a full fitness retreat, taking a class on its own is one of the more memorable activities in Koh Samui and an easy way to experience a sport that is such a big part of Thai culture.
Most gyms offer group classes, private lessons, or both, so you can easily try a single session during your trip. Some also offer longer training packages and accommodation for people who want Muay Thai to be a bigger part of their stay.
Some Muay Thai gyms in Koh Samui to consider include:
- Evolution Samui Muay Thai & Boxing: Located in Lamai and connected with Lamai Fitness Retreat. This is where I trained during my two-week retreat. Location
- Dock & Kitty Muay Thai Gym: Another option in Lamai for Muay Thai training. Location
- Sing Samui Muay Thai: Located in the Chaweng area. Location
- Super 8 Muay Thai Gym: Another Muay Thai gym in Chaweng. Location
- Tom Muay Thai: Located near Chaweng. Location
If you enjoy the class, you can also watch a live Muay Thai fight while you are on Koh Samui, which I cover separately above.
10. Spend the Day at a Koh Samui Spa and Sauna
Wellness is a big part of the scene in Koh Samui, especially around Lamai. Along with traditional Thai massage and spas, you’ll also find sauna and recovery facilities with steam rooms, hot and cold plunge pools, ice baths, swimming pools, and places to relax between workouts.
We went to LUUMA in Lamai several times during my two-week fitness retreat. It became one of our favorite places to recover after training. We would rotate between the dry sauna, steam room, hot and cold pools, and ice bath, then spend the rest of the afternoon relaxing by the outdoor pool.
A lot of the crowd came from the fitness retreats, Muay Thai gyms, and other workout programs around Lamai. Some people came right after training, while others used their days off to recover and spend a few hours there.
LUUMA felt more like a place to settle in for the afternoon than a traditional spa appointment. There was a full restaurant, loungers around the pool, beach chairs, and even places where you could sit with a laptop if you needed to get some work done.
If you are doing Muay Thai, joining a fitness retreat, or simply looking for a relaxing break from sightseeing, a Koh Samui spa or sauna can be an easy activity to work into your trip. It is also a good option on a rest day when you still want to get out without planning another full excursion.
11. Get a Massage in Koh Samui
Massage shops are everywhere in Koh Samui, from the main tourist areas to small streets around Lamai and Chaweng. They are also very affordable compared with what you would typically pay in the U.S., which makes it easy to work a massage into your trip more than once.
During my two weeks at the fitness retreat, I usually went for a massage several times a week, either after we finished training for the day or sometimes around lunch between workouts. Other people from our retreat and nearby fitness programs did the same, especially after harder training days.
Foot massages were what I booked most often. They are inexpensive, easy to find, and much more casual than booking a full spa treatment. If you have never walked into one of these massage shops before, it can feel a little unusual at first, but you quickly realize how common they are and how many people stop in for an hour during the day.
If you want something stronger, you can also try a traditional Thai massage. Instead of simply working the muscles with their hands, the therapist may use their body weight to apply pressure and move you through a series of stretches. It can be much more intense than a foot or oil massage, and some of the stretching can definitely hurt if you are tight from traveling or working out.
For most visitors, I would start with a foot massage or regular body massage and then try a Thai massage if you want a more traditional and much deeper experience.
12. Hike to the Na Muang Waterfalls
The Na Muang Waterfalls are among the best-known natural attractions in Koh Samui and are a good break from the beaches and resort areas. The name is often translated as “Purple Waterfalls,” a reference to the purple-gray color of the surrounding rock.
There are actually two separate waterfalls here, usually referred to as Na Muang 1 and Na Muang 2. Na Muang 1 is the easier one to visit and only requires a short walk from the parking area. The waterfall drops into a large natural pool, and depending on the conditions, you may see people swimming or cooling off in the water.
Na Muang Waterfall 1
If you mainly want to see one of Koh Samui’s waterfalls without doing a difficult hike, I would start with Na Muang 1. You can drive close to the entrance and then walk roughly 10 minutes to reach the falls. There are also food and drink vendors around the entrance area.
The rocks around the waterfall can be very slippery, especially after rain, so I would wear shoes with decent traction rather than flip-flops if you plan to climb around or get close to the water.
Na Muang Waterfall 2
Na Muang 2 is the more adventurous option. It sits farther into the hills and requires a steeper hike, with some sections that can involve scrambling over rocks. One commonly cited route takes around 30 to 40 minutes from the base to the upper viewpoint.
The trail can become difficult and slippery when wet, so I would skip the upper hike during heavy rain or if you are not comfortable on rough terrain. Recent visitor reports also describe sections as poorly marked, so this is one of those places where good footwear and a little extra caution matter.
How to Get to Na Muang Waterfalls
The waterfalls are in the interior of southern Koh Samui, about 12 kilometers south of Nathon and roughly a 30-minute drive from Lamai Beach. You can reach Na Muang 1 fairly easily by rental car, scooter, taxi, or as part of an island sightseeing tour. Parking is available close to the trailhead.
If you are driving yourself, follow Koh Samui’s main ring road toward Na Muang and then look for signs directing you inland toward the waterfalls.
I would allow around one to two hours if you are visiting Na Muang 1 and taking your time around the pool. Plan longer if you want to hike toward Na Muang 2 or combine the waterfalls with other attractions in the southern part of Koh Samui.
13. Explore Ang Thong National Marine Park
Ang Thong National Marine Park is one of the best day trips from Koh Samui and one of the most scenic places to visit in the area. The protected archipelago sits about 20 kilometers from Koh Samui and includes 42 limestone islands scattered across the Gulf of Thailand.
Most trips spend a full day moving between several islands, with a mix of snorkeling, kayaking, beach time, and short hikes. The exact itinerary varies by tour and weather conditions, but the two best-known stops are Koh Mae Ko, home to the Emerald Lake, and Koh Wua Talap, where you can hike to one of the park’s panoramic viewpoints.
See the Emerald Lake on Koh Mae Ko
One of the signature sights in Ang Thong is the Emerald Lake, a saltwater lagoon surrounded by steep limestone cliffs on Koh Mae Ko. Reaching the viewpoint involves climbing a steep set of stairs, but from the top you can look down into the green-blue lagoon and across the surrounding islands. Swimming in the lagoon itself is not allowed.
The climb can be steep and uneven, so this is another place where I would bring proper shoes rather than rely on flip-flops, especially if you plan to do the full hike.
Snorkel and Kayak Between the Islands
Many Ang Thong tours also include snorkeling and kayaking. Kayaking is one of the best ways to get closer to the limestone cliffs and smaller coves, while snorkeling stops vary depending on the sea conditions and the route chosen that day. Standard day tours commonly combine these activities with lunch and beach time.
How to Get to Ang Thong National Marine Park
You cannot drive or take a normal public ferry to Ang Thong. For most visitors, the practical way to get there is on an organized boat tour from Koh Samui. There is no regular passenger boat service running directly into the national park.
Tours generally use either a larger boat or a speedboat. Larger boats take longer to reach the park but usually offer a more relaxed ride, while speedboats cut down the travel time and give you more time at the islands. Many tours include hotel pickup and return transportation as part of the package.
Because this is a full-day trip, I would keep most of the day open rather than trying to combine Ang Thong with other Koh Samui attractions. If you only have a few days on the island, this is one of the excursions I would prioritize.
14. Take a Thai Cooking Class
Taking a Thai cooking class is a good way to do more than just eat your way through Koh Samui. Most classes are hands-on and walk you through how to prepare several Thai dishes, often with a focus on ingredients and techniques you can actually use again at home.
Some classes also include a visit to a local market, where you can learn more about herbs, vegetables, sauces, and other ingredients used in Thai cooking before heading back to the kitchen. That can make the experience feel more connected to the island rather than just taking a class inside a cooking school.
Cooking classes are also one of the easier Koh Samui activities to fit into a trip because they usually only take part of a day. They work well for solo travelers, couples, or small groups, and they are a good option if you want a break from beaches and outdoor activities.
A few cooking schools in Koh Samui to look into include:
- Lamai Thai Cooking School: Located in Lamai and convenient if you are staying on the southern side of the island. lamaithaicooking.com
- Smiley Cook: Offers Thai cooking classes on Koh Samui with a focus on traditional dishes and hands-on preparation. smileycook-samui.com
- Island Organics: Another option for travelers interested in Thai cooking and local ingredients. islandorganicssamui.com
If food is a big part of why you travel, a cooking class is one of the more practical ways to learn about Thai cuisine while still doing something interactive during your time on Koh Samui.
15. Explore the Secret Buddha Garden
The Secret Buddha Garden is one of the more unusual attractions in Koh Samui and a good stop if you want to see something away from the beaches and resort areas. Also known as Tarnim Magic Garden, it sits high in the hills in the island’s interior and is filled with statues, small shrines, waterfalls, and pathways surrounded by dense tropical vegetation.
The garden was created by local farmer Nim Thongsuk, who began building the statues and landscaped grounds later in his life. Today, you can walk through the property and see figures inspired by Buddhist mythology, animals, musicians, and other characters tucked into the hillside.
Part of what makes the Secret Buddha Garden interesting is the drive into Koh Samui’s mountainous interior. The roads become steep and rough in places, so this is not somewhere I would recommend trying to reach on a basic scooter unless you are very comfortable riding. A 4×4 vehicle or an organized island tour is usually the easier option.
Once you arrive, allow some time to walk through the garden and explore the different levels. There are stairs and uneven paths, so comfortable shoes are a better choice than flip-flops.
I would not plan an entire day around the Secret Buddha Garden, but it works well as part of a trip through the interior of Koh Samui, especially if you are also visiting viewpoints, waterfalls, or other attractions away from the coast. It is one of the more unique things to see in Koh Samui and gives you a very different look at the island than the beaches of Chaweng or Lamai.
16. Visit the Grandfather and Grandmother Rocks
The Grandfather and Grandmother Rocks, known locally as Hin Ta and Hin Yai, are one of the more unusual tourist attractions in Koh Samui. The natural rock formations sit along the coast just south of Lamai Beach and are famous because their shapes resemble male and female genitalia.
There is also a local legend tied to the rocks. According to the story, an elderly couple was traveling by sea to arrange a marriage for their son when their boat was caught in a storm and sank. The couple drowned, and the rocks are said to have formed as a symbol of their intentions and honesty.
The rocks themselves do not take long to visit, so I would treat this as a quick stop rather than plan a large part of the day around them. They are easy to combine with other things to do around Lamai, especially if you are already visiting the southern end of the beach.
Afterward, stop at Rock Bar, a quirky Jamaican-themed bar built into the rocks nearby. It is one of the more distinctive places to grab a drink in Lamai and makes the stop more worthwhile than visiting the rock formations on their own.
17. Relax at Silver Beach (Crystal Bay)
Silver Beach, also known as Crystal Bay, is a small cove between Chaweng and Lamai that feels much quieter than either of the island’s larger beach areas. The beach is relatively short, with clear water, soft sand, and large rocks around the edges of the bay.
We came here a couple of times with my fitness retreat for early-morning open-water swimming. At that hour, the beach was very quiet, and even later it never felt especially busy when I was there. It was a nice contrast to the much larger stretches of sand in Chaweng and Lamai.
Because Silver Beach sits between the two main resort areas, it is not somewhere most people will walk to. You will generally need a scooter, taxi, or car to get there. Once you arrive, though, there are a few places to eat and drink along the beach, including a good beachfront restaurant where you can stay for lunch after swimming.
If you want a smaller and more relaxed beach in Koh Samui, Silver Beach is an easy place to spend a few hours swimming, snorkeling, or simply getting away from the busier resort areas.
18. Take a Day Trip to Koh Tao or Koh Phangan
Koh Samui is well positioned for visiting some of the other islands in the Gulf of Thailand, especially Koh Tao and Koh Phangan. Both can be reached by ferry or speedboat, but I would think of them as two very different day trips rather than trying to see both in one day.
Koh Tao
Koh Tao is the better choice if you want to spend the day snorkeling or scuba diving. The island is known for its clear water, coral reefs, and dive sites, and many organized day trips from Koh Samui combine Koh Tao with nearby Koh Nang Yuan for snorkeling, beach time, and a short viewpoint hike.
You can also take a regular ferry from Koh Samui to Koh Tao and explore independently. The fastest current crossings are around 1½ hours, although travel time varies by departure pier, operator, and boat.
If your main goal is getting in the water, I would lean toward an organized snorkeling or diving trip rather than spending a large part of the day figuring out transportation once you arrive.
Koh Phangan
Koh Phangan is much closer to Koh Samui and is an easier island to visit independently for the day. It is best known internationally for the Full Moon Party, but there is much more to the island than nightlife, including beaches, small towns, viewpoints, and a much quieter side once you get away from the party areas.
Current ferry crossings from Koh Samui generally take around 30 to 50 minutes, depending on the route and operator. Ferries run from several piers on Koh Samui, so I would check the schedule for the dates of your trip rather than assume you need to leave from Nathon.
If you are visiting specifically for the Full Moon Party, I would treat that differently from a normal sightseeing day trip and plan your transportation around the event schedule.
Between the two, I would choose Koh Tao for snorkeling and diving and Koh Phangan for an easier island-hopping day with beaches and exploring on land. Both make good day trips from Koh Samui, but Koh Tao requires more travel time and is better suited to a full-day excursion.
19. Visit a Koh Samui Viewpoint
Wat Teepangkorn was the viewpoint I visited, but there are several scenic overlooks around Koh Samui. Other popular options include Lad Koh Viewpoint between Chaweng and Lamai, Lamai Viewpoint, Overlap Stone, and Khao Hua Jook.
We ran up to Wat Teepangkorn one morning as part of my fitness retreat. The temple sits high in the interior of the island near the Phra Buddha Dipankara statue, and the views stretch across the green hills toward the coast. It was also much quieter than many of the better-known attractions closer to the beaches.
One of the things I remember most was a woman selling fresh mango and bananas at the top, which was very welcome after the run. The roads into the hills can be steep in places, so if you are not arriving as part of a workout like we did, a car, taxi, or organized tour may be more practical than trying to walk up from the main road.
If you want to add one of the Koh Samui viewpoints to your itinerary, I would choose based on where you are staying and what else you plan to do that day rather than making a special trip across the island for one specific overlook.
How Many Days Do You Need in Koh Samui?
I would plan on at least four or five days in Koh Samui if you want enough time to see several of the main attractions without spending the entire trip rushing around the island. That gives you time for beaches, temples, night markets, and a few other activities while still leaving room to relax.
With three days, I would focus on the highlights. Visit Big Buddha and Wat Plai Laem together, spend some time around Chaweng or Lamai, visit Fisherman’s Village or a night market in the evening, and choose one larger activity such as Ang Thong National Marine Park.
With five to seven days, you can slow things down and add Na Muang Waterfalls, Silver Beach, a cooking class, Muay Thai fight, massage, spa or sauna, and some of the attractions in the island’s interior. You will also have enough flexibility to spend part of a day simply relaxing on the beach rather than filling every hour with sightseeing.
If you have a week or longer, Koh Samui also works well as a base for day trips to Ang Thong, Koh Tao, or Koh Phangan. Longer stays make even more sense if you are coming for Muay Thai, a fitness retreat, or another workout program, which was the reason I spent two weeks on the island.
Final Thoughts on the Best Things to Do in Koh Samui
Koh Samui has enough variety that you can build a very different trip depending on what you enjoy most. You can spend your time on beaches and at night markets, visit temples and waterfalls, watch Muay Thai, take a cooking class, or head out on a full-day boat trip.
What I liked most was having enough time to mix the well-known Koh Samui attractions with experiences that became part of my everyday routine, especially the fitness retreat, Muay Thai, massages, and evenings around Lamai.
If it is your first trip, I would focus on a mix of the island’s major sights and a few experiences that fit your interests rather than trying to see everything. Koh Samui is large enough that leaving some time to slow down, explore different areas, and enjoy the beaches can be just as worthwhile as checking another attraction off the list.
Koh Samui Things to Do FAQ
What are the must-do things in Koh Samui?
For a first trip, I would prioritize a mix of Koh Samui’s beaches, cultural sights, and one or two bigger excursions. Big Buddha, Wat Plai Laem, Fisherman’s Village, a night market, and either Chaweng or Lamai are all easy to work into a trip. If you have a full day available, Ang Thong National Marine Park is one of the bigger excursions worth considering.
What are the best things to do in Koh Samui at night?
Chaweng has the busiest nightlife in Koh Samui, with beach clubs, bars, and nightclubs around Chaweng Beach, Soi Mango, and Soi Reggae. For something more relaxed, I preferred evenings around Lamai or Fisherman’s Village, where you can combine dinner with bars, night markets, live music, or a Muay Thai fight.
What are some free or inexpensive things to do in Koh Samui?
Many of Koh Samui’s beaches are free to visit, and temples such as Big Buddha and Wat Plai Laem can also be inexpensive stops. Walking through Fisherman’s Village or a night market costs nothing unless you buy food or drinks. Massages are another relatively affordable activity by Western standards, although prices vary depending on the type of treatment and where you go.
What are the best things to do in Koh Samui when it rains?
A rainy day is a good time to book a Thai cooking class, get a massage, visit a spa or sauna, or spend some time at a cafe or restaurant. Short tropical showers are also common, so I would not automatically cancel an entire day of sightseeing unless the weather is expected to stay bad.
Is Koh Samui good for nightlife?
Yes. Chaweng has the island’s biggest nightlife scene and is the best choice if you want clubs and late-night bars. Lamai also has plenty of nightlife, but it is smaller and more laid-back. Fisherman’s Village is better for dinner, drinks, live entertainment, and a more relaxed evening.
What are some unique things to do in Koh Samui?
Some of the more unusual experiences include taking a Muay Thai class, watching a live Muay Thai fight, joining a fitness retreat, visiting a sauna and cold-plunge spa, taking a Thai cooking class, and exploring the Secret Buddha Garden. These were some of the activities that made my time on Koh Samui feel different from a standard beach vacation.
