Koh Samui is the perfect island retreat for anyone wanting a mix of beautiful beaches, waterfalls, Buddhist temples, and modern amenities. With beautiful landscapes and natural beauty combined with cultural experiences and adventure, there are plenty of things to do in Koh Samui to fulfill every traveler’s needs.
Situated on the Eastern side of the Thai mainland in the Gulf of Thailand in the province of Surat Thani, Samui Island is the second-largest island in the Thai Kingdom (Phuket being the biggest). Koh Samui and Phuket have been compared countless times in an attempt to debate which island is the best, but to me, it is really impossible to choose a clear winner. You can read about Phuket here to help you make your choice.
Regardless, you should visit both islands when traveling to Thailand, in fact, it’s a great idea to go island hopping to see as many as you can. Nothing can really compare to the beautiful beaches of the country.

Things to do in Koh Samui, Thailand
Visiting the Islands of South Thailand is the ultimate beach vacation and Koh Samui is one of the most popular places to enjoy the beach. While relaxing at the beach is a huge part of visiting Koh Samui, there are plenty of other things to see and do as well. So make sure to spend at least three days of your trip in Thailand on Koh Samui.
This post was originally written by Albert of Here to Stay who lived in Thailand, but it has since been updated with new hotels, tours and information by The Planet D.
Beach Life at Chaweng Beach
Koh Samui is blessed with white sandy beaches making it the perfect beach vacation in Thailand. Chaweng Beach is Koh Samui’s most popular beach and with good reason. It is one very large stretch of white sand with shady palm trees. In fact, it is so large it is broken into four parts, North, Central, South, and Little. (Chaweng Noi). If you want to be in the heart of the action, this is the place to stay.
There are plenty of water activities right on the beach at Chaweng making it the perfect place to spend the day. Try your hand at snorkeling and sea kayaking or rent a paddleboard and try stand-up paddleboarding in the calm waters. It’s our favorite watersport. When the sun goes down, the nightlife begins on Chaweng Beach at its beach bars. For a taste of Koh Samui’s party scene, head out to the Green Mango strip for some bar hopping.
Where to Stay on Chaweng Beach
- Kings Island Resort is a highly rated place to stay on Chaweng Beach. There is no swimming pool but it is located directly on the beach.
- The Hyatt Regency is one of the most luxurious properties on the beach with a private swimming pool at a mid-range price.
Visit Grandpa and Grandma Rocks at Lamai Beach
Lamai Beach is quieter than Chaweng Beach and tends to attract a more laid-back crowd. This is a great beach for swimming and hanging back while enjoying the laid back Thai beach life. There are beach bars and restaurants and it is another popular place to make a base while exploring the island.
Koh Samui may be famous for its white sandy beaches, but the rocky beaches are definitely a sight to remember. It is at Lamai Beach that you will find the famous Koh Samui attractions of Grandfather and Grandmother Rocks.
Where to Stay at Lamai Beach
- Lamai Samui is a luxurious retreat with villas and suites on the water. Some villas have their own private plunge pools, infinity pools, and private dining pavilions.
- One of the closest places to stay near the rocks is Beluga Boutique Hotel. This adult-only hotel is a secluded escape with an infinity pool, lounge bar, modern amenities and restaurants right on the beach.
Hin Ta and Hin Yai Rocks
Hin Ta and Hin Yai rock formations (Grandfather and Grandmother Rocks) are some of the more unique things to see on Koh Samui. The male and female genitalia-shaped rock formations have been a top draw since our first visit to Koh Samui way back in 2003. (and long before we ever arrived on Ko Samui).
Legend has it that an old man and woman set sail to a neighboring island to ask for the hand of a daughter of a man named Ta Monglai. When their boat capsized, they drowned and turned into these rocks to prove their true intentions to the family. It is a unique thing to see and it is also a beach on Koh Samui that offers some higher-end accommodation options.
Bouldering at Chaweng and Lamai Beach
We learned to rock climb in Thailand at Railay Beach and now, bouldering is popular on Koh Samui at Chaweng and Lamai Beach. It makes sense with their massive boulders. Its limestone walls have started attracting people honing their bouldering skills along the rocky beaches. With walls reaching up to 40 meters (120 feet) both Chaweng and Lamai beach are also popular for rappeling.
See the Big Buddha Temple
One of the top things to do in Koh Samui is to visit Wat Phra Yai Temple to see the 12 meter high (39 foot high) Big Buddha. It was built in 1972 and has endured as one of Koh Samui’s top attractions.
Even though it isn’t technically located on Koh Samui, it is Koh Samui’s most famous landmark. The Big Buddha Temple is located on Koh Faan and connected to Koh Samui by a long causeway. Plus it is usually the first thing people put on their list to see as in Koh Samui as it can be seen by air upon arrival. This temple is a popular spot to celebrate Loy Krathong and Songkran Festivals in Thailand as well.
If you are looking to get acquainted with Koh Samui’s top attractions quickly, This half-day cycling tour lets you discover Koh Samui’s most famous sights including the Big Buddha, the Bang Rak Market, and the Choeng Mon Beach as you learn about the island’s culture and history from a local guide. We love taking a guided tour when we arrive at a new destination, it lets us see a lot of places in a couple of hours giving a great overview for the rest of the trip.
Wat Plai Laem
Another cool temple to see in Koh Samui is Wat Plai Laem. This Buddhist temple showcases Koh Samui’s Chinese heritage with a giant Guanyin statue dominating the temple grounds. Even though this is a Buddhist temple, it is actually dedicated to the Chinese Goddess Guanyin who is believed to be the Goddess of unconditional love.
A very unique thing to keep an eye out for is when you make a donation, you will receive a bag of fish food so you can feed the resident fish in the pond.
Khao Hua jook Chedi
While at Lamai Beach, make sure to go up to Wat Khao Hua Jook. It offers panoramic views of the island. It is easy to get “Watted out” When visiting Thailand. After a while, I know we have seen enough of them, but this one is worth it for the view of the valley and the coastline of Koh Samui. Plus, if you are looking to do a bit of hiking after spending too much time on the beach, this is a good walk.
If you are looking for something truly unique, keep an eye out for Overlap Stone, a large stone that rests precariously on top of a large boulder
Laem Sor Pagoda
If you are looking for a quiet place to stay away from the busy atmosphere of Lamai Beach and Chaweng Beach, Laem Sor Beach is located 20 minutes from Lamai Beach on the south side of the island. Laem Sor Pagoda is the top draw here to see the beautiful golden temple on the beach, but there are some resorts and beach bars in the area as well.
- Laem Sor Residence gets high reviews on TripAdvisor with a private pool located on a sandy beach with shallow waters.
Go Snorkeling
One of the best things to do in Koh Samui is to enjoy all of its water activities and snorkeling is one of the best things of them. Each island in Thailand offers its own unique quirks and customs but I must say, the thing that stood out the most to me about Koh Samui was the incredible snorkeling and scuba environments it had to offer. There are several boat tours that will take you out to see the coral reefs and sea life of Samui. You can also go snorkeling at Ang Thong National Marine Park.
This private long tail boat tour has you boarding one of Thailand’s famous longtail boats to Koh Taen, known for its marine life and coral reef. Plus you will get to visit Koh Madsum (Pig Island) to see the resident pigs that live there. We did this in the Bahamas and it is so much fun to see the pigs running in the sand to say hello. Other things you see are, White Rock Cave Island, Red Ant Island, and Matkhong Island
Scuba Diving
The neighboring island of Koh Tao is known for its scuba diving, but Samui is also an excellent scuba diving destination. There are many places offering scuba diving courses on the island at affordable prices. Plus the warm, clear, and inviting waters make it an ideal spot to become certified.
Scuba Diving courses are run right off Chaweng Beach, Coral Cove, and other beaches on Koh Samui with shore diving that is easy to access. Ang Thong National Marine Park is also considered a great diving destination.
Mummified Monk – Wat Khunaram
One of the strangest things to see on Koh Samui is the Mummified monk. Located at Wat Khunaram, the mummified remains of Monk Luong Pordaeng are on display. The Buddhist monk died in 1973 in a seated meditative position. Before his death, he asked that his body be put on display should it not decompose. And now today, it is revered as an inspiration to follow a life of Buddhism.
We saw this monk on our first visit to Koh Samui and it’s not as shocking as it sounds as he is sitting behind glass so you do feel a little detached. One of the more unique things you can do is to attend a Monk Chat and meditation session at Dipabhavan Meditation Center for unique insight into this way of life. This is open to anyone.
Take a Thai Cooking Class
One of the best ways to immerse in a culture is through food. Thai food is our favorite and we eat it at home all the time! Visit a local market and learn to cook Thai cuisine. as you learn to prepare meals that you can bring home with you. It’s a fun and interactive way to spend an evening. Read more: Best Thai Food – Traditional Thai Dishes to Eat in Thailand
Book this cooking class details here – Choose four Thai dishes to prepare and then visit one of Koh Samui’s local street markets for fresh ingredients. You can book it here, with easy cancellation within 24 hours of activity for a full refund.
Check out the Night Markets
One of our favorite things to do in Thailand is to go shopping and sample their many small food stalls. Chiang Mai is famous for its night markets, but Koh Samui also has fabulous night markets that rotate locations each evening. Pick up your Thai souvenirs, sample great street food, and get lost in the energy and excitement of bartering with the vendors.
Best night markets in Koh Samui
- Fisherman’s Village Walking Street at Bophut on Fridays.
- Lamai Night Plaza Night Market in Lamai Centre – Wednesdays, Thursdays, and Sundays.
- Chaweng Night Market in Bophut- Monday to Thursday and Saturday.
Fisherman’s Village in Bo Phut
Even if you don’t make it to Fishermen’s Village night market, it is a great walking street during the day. Once a thriving fishing village, Fisherman’s Village has now turned into It is filled with cafés and eateries. You can do some shopping and Bophut Beach is located right there as well. The village is lined with rustic-style buildings, boutiques, trendy restaurants, and bars along the main road.
The main section of Fisherman’s Village is Bophut Beach Road which lines the beach. Visitors can go into one of the shops or cafés and head out back for beautiful beach views.
Take a Koh Samui Jeep Tour
A fun way to see all the Koh Samui highlights is to take a jeep tour. See the secret lookout offering gorgeous views of the Gulf of Thailand, visit the waterfalls and the Buddha Garden. For a unique tour of Koh Samui, this is a great idea. Check out this top-rated jeep tour on Ko Samui and this day trip to Koh Phangan.
Swim in the Namuang Waterfalls
Namuang Waterfall is probably one of the top attractions located in central Koh Samui. Located inland from Nathon Bay, it is easily accessible by tuk tuk. Once you reach the parking lot, Na Muang 1 is just a short walk from the parking lot. Venture up another 100 meters to see Na Muang 1.
I must admit, I was very skeptical about visiting Na Muang because it is a very touristy place. But I was told when I get there I should climb up next to the waterfall as far as I could, “to see secret very beautiful waters”.
Na Muang 2
Tourists were crowding at the base of the Na Muang Waterfalls but if you are willing to climb at bit, you will have a quieter less crowded visit. As I climbed the steep little path I reached quite a few smaller but undisturbed waterfalls, each with its own little pools.
I climbed even higher and eventually reached the top. This was what I wanted to see, a totally unspoiled waterfall with lush jungle growing on either side, I discovered the “secret very beautiful waters”.
The view I had of the island was unbelievable and I couldn’t see or hear any tourists. It was heaven! I spent almost the whole day taking pictures, swimming, and eating the odd coconut that came floating down the stream.
Have a Traditional Thai Massage
Really, no matter where you are in Thailand a traditional Thai Massage should be on your list. And Koh Samui is no exception. I love getting a Thai massage on the beach and this is one of the must-do things in Koh Samui. Don’t worry about finding one, they will be walking the beach in search of tourists to soothe their aching bodies. If you don’t want to have a massage on the beach, go to a spa at one of the resorts for the 5 star treatment.
But you can also walk along the streets to find massage parlors or book a fancier massage at one of the higher-end hotels. But do yourself a favor, get a massage as much as possible in Thailand. They are so affordable and it is nice to get pampered like royalty on a regular basis.
Indulge in Wellness and Fitness
If you want to take your wellness holiday to another level, make sure to stay at the Absolute Sanctuary. This wellness fitness resort is nestled on a hill overlooking the Gulf of Thailand. Located within a lush forest setting, Absolute Sanctuary takes a holistic approach seeking to address individual wellness goals such as a detox holiday, pamper-me holiday, weight management or reducing stress.
Indulge in yoga or Pilates as you enjoy a meaningful holiday that will bring peace to your mind and body. If you are looking for a wellness retreat, you can view rates and availability here.
Go for a Hike To Secret Buddha Garden
Koh Samui has some great hiking and if the beach life becomes a little tedious (I mean, how could it ever really though?) or you want to stretch your legs, head out to some of the trails for a hike.
Secret Buddha Garden (also known as Namtok Tar Nim & Magic Garden) is a very interesting place to visit. Created in 1976 by a local durian fruit farmer, there are several different Buddha Sculptures depicting different Buddha folklore.
There are plenty of other places to hike on Koh Samui besides Secret Buddha Garden to see Buddha including a hike on the Nathon Mountain Trail Ridge or head up to the Maenam Viewpoint for great views of Nathon and the beautiful tropical island scene.
- This Koh Samui Trek takes you on a hike to some of the most beautiful viewpoints on Koh Samui with a stop at the Secret Buddha Garden, the highest temple on the island and a local museum.
- You can hike to Secret Buddha Garden or take a 4X4 Jeep Tour. Check out tour options here.
Ang Thong National Marine Park
A must-do day trip from Koh Samui is to head out to the Ang Thong National Marine Park. Like so many places in Southern Thailand, Ang Thong was featured in the movie The Beach with Leonardo DiCaprio. We highly recommend reading the book as well before visiting Thailand. The country has changed a lot over the years, but it really captures the feeling we had on our first backpacking trip to Thailand in 200.
Ang Thong National Park is an archipelago of 42 islands with the towering limestone mountains that Thailand is famous for. You can swim in lagoons, relax on pristine beaches, or go snorkelling and spy sea turtles in its crystal clear waters.
Both Koh Samui and Koh Phangan are part of the Ang Thong National Marine Park and it can be visited on a day trip. For the ultimate in luxury, book an overnight cruise on a junk boat to experience the islands in private.
Day Trip to Koh Phangan
We mentioned island-hopping while visiting Koh Samui above and we mean it. Thailand was made for island hopping. From Koh Samui, you can easily visit Koh Phangan and Koh Tao on boat tours from Koh Samui.
Koh Phangan is popular enough to spend some time on in its own right, but if you simply want to visit for a day, this Full day Tour takes you to see all the highlights of Koh Phangan.
The island is just a 30-minute boat ride from Koh Samui where you will land at Thong Sala pier. On this tour, you will explore the Chinese Temple, Koh Mah beach for snorkeling in its crystal-clear waters followed by traditional Thai lunch. Then it is time to visit the scenic viewpoint of Koh Raham before heading back by speedboat to your hotel in Koh Samui.
Koh Tao
Koh Tao to explore peaceful hidden beaches, underwater sanctuaries filled with sea creatures, and all-night parties. Koh Tao is one of the best spots for snorkelling and diving in Thailand. Koh Tao is often referred to as Turtle Island for both its shape and the green and hawksbill turtles that inhabit the beautiful island. It is also one of the best places in Thailand to take your PADI certification. Read more at Beautiful Beaches in Thailand to Spark Your Wanderlust
Go to an Elephant Sanctuary
Elephants have long suffered in Thailand, but thanks to sanctuaries converting from elephant tours to ethical elephant sanctuaries, you can visit retired tourism elephants and help support their well being.
Take a 40 minute drive through the other side of the island to a sanctuary where you will learn about the rescued elephants, feed them and help bath them in mud. These elephants have been rescued and these sanctuaries are an important part in letting them live out their days in relative peace. While they can never go back in the wild, it is a much better life than having tourists ride on their backs. Find out more about the elephant sanctuary tour here.
Rent a Scooter – But Be Careful
Koh Samui offers a lot of touristy sights to explore. The best (and cheapest) way to see everything is by renting your own scooter. I understand that this is a daunting idea to most newcomers to Southeast Asia, but it only takes a couple of minutes for you to get the hang of it and feel like a hardcore biker.
Make sure that you wear a helmet at all times and drive safely. Sadly, many tourists die on the roads of Thailand every year, so be extremely careful. Dave and I had an accident in Koh Samui and burnt our legs very badly, so be sure that you know how to ride a motorcycle before renting one.
Invest in an island map and ask a local to indicate all the must-see locations. Naturally the next thing to do is to completely ignore the map and just get lost! This is the best way to find hidden gems. A Motorcycle Adventure, the Journey Begins
Chill out after Dark
After you’ve soaked up some rays all day long, head out to the beach to enjoy dinner and drinks on a matt on the beach. Each night, the lanterns are lit and the lounge chairs come out as you eat on the beach harem style laying down chillaxing with a Chang or Singha Beer.
This Sunset Tour with a Thai Beach Dinner takes you on an evening tour to see some of Koh Samui’s top tourist attractions including, a night market, the Hin Ta Hin Yai Rocks, and sunset at Laem Sor Pagoda before finishing off with a Thai dinner on the beach.
Lady Boy Cabaret Show
If you are looking for other things to do in Koh Samui at night, check out a Lady Boy Cabaret. Like the days of La Cage Au Folles in North America. (Way back in the 1990s), the Lady Boy Cabaret Shows have become one of the very best things to see in Koh Samui at night. This energetic performance involves lip-synching, dancing, and elaborate costumes.
If you want something with more action, Muay Thai fighters put on demonstrations around the island as well. You can also make your way to Chaweng Boxing Stadium to watch a Muay Thai match. You can also do some Muay Thai training on Koh Samui. We did this in Phuket and it was an amazing way to immerse in Thai culture.
Getting Around Koh Samui
I know we mentioned rending a scooter to get around, but for a safer option we recommend a car rental. You can compare prices here.
How to Get to Koh Samui
Koh Samui is located in the Surat Thani province 35 km off the coast of Surat Thani on the Gulf of Thailand. The town of Surat Thani is the main jumping-off point for the small islands on the Gulf of Thailand and you can easily catch regular ferries from here.
Neighboring islands are Ko Pha Ngan, Ko Tao, and Ko Nang Yuan which can all be reached by longtail boat or ferry.
There are internal flights available from Phuket to Koh Samui as well as Bangkok to Koh Samui making it an easy destination to visit during your Thailand travels.

From Surat Thani, you will catch the ferry to Koh Samui from the main Surat Thani ferry port at Donsak Pier.
Where to Stay on Koh Samui
Koh Samui is known for its luxury resorts but there are also places that are more affordable. But here are some recommendations to get you started.
- Four Seasons Resort – Expensive but worth the splurge. you can never go wrong with the Four Seasons brand if you are in search of a luxury stay.
- Kings Island Resort is a highly rated place to stay on Chaweng Beach. There is no swimming pool but it is located directly on the beach.
- The Hyatt Regency is one of the more luxurious resorts on the beach with a private swimming pool at an affordable price for mid-range travelers.
- For other hotels on Koh Samui, check out TripAdvisor for reviews.
So, now you know the best things to do in Koh Samui, Thailand. When you book your next trip to the Land of Smiles, be sure to add it to your itinerary.
Koh Samui has a lot more to offer other than waterfalls and coral reefs but these were the things that stood out the most to me. It is a beautiful island with breathtaking lush jungle and amazing beaches with shady palm trees, maybe I should leave Phuket and move here. Koh Samui will definitely see me again in the near future.

It’s a best destination to visit,I think everybody must go there once in a lifetime.
Thailand is such a nice place. I have visited that place once together with my family. The foods are really delicious and the people are really good!
I’ve spent so much time in Thailand and still haven’t visited Koh Samui. Looks like I’m going to have to get myself there!
Ha! I did this about 20 years ago in my twenties and hope to do it again next year. We are in Spain now, but plan for SE Asia next. Can’t wait. Thanks for sharing and bringing back great memories.
Love that bamboo bridge.
Koh Samui looks stunning! And quite the nice little getaway you discovered by hiking farther up than the normal tourist would. I’ll be reaching Thailand in November and you are definitely giving me ideas for places to visit, thank you!
Hey Ryan, have an amazing time in Thailand. You are going to love it. One thing we find is that it is a big enough country that you can still get off the tourist path, even in the touristy places. Albert definitely showed a different side to Koh Samui. It was one of our favourite islands in Thailand, and we look forward to going back one day.
Finding hidden gems always makes the best moments when travelling. I’ve been to Koh Samui, but not for long. I definitely want to go back and try and find this waterfall.
We agree, there are always quiet places that only the locals know about and if you are lucky or if you stick around a spot long enough, you can happen upon them. We spent about a week there years ago and definitely want to go back.
I love the red color on the second and third picture of the temple. I wish I can visit the place too.
It is called Wat Ratchathammaram (Red Temple) and I took thousands of pictures of it. It is beautiful.
Beautiful! From what I understand, Koh Samui has fabulous restaurants and resorts as well as a vibrant yoga scene and affordable, eco-friendly accommodation & delicious detox / raw / juicing community with resorts dedicated to all of these practices. Amazing all around!
Thanks for the update on Koh Samui. We were last there in 2003 ourselves, so I can only imagine how much it has changed. This article has made us want to go back!
We’re going to Koh Samui in November! We’ll have to look for the secret waterfall path.
Have a great time, you are going to love Thailand and it’s even better when you get a chance to find a secret place.
Just keep on climbing and climbing. It is definitely worth the effort! Thanks for reading.
Can’t wait until we get to Thailand. Just look at the color of that water. Definitely don’t see that where we are now (England)!
Very cool post! You were lucky to find that random Thai guy. It seems he knows the place well.
Yes I was really lucky to have found the guy. I always go out of my way to chat to the locals…they always seem to guide me in the right direction. Thanks for reading the post!
Koh Samui sounds like an excellent place to let your hair down! Very informative post!
It is an amazing place you have to make a plan to see it. Thanks for reading!
