Koh Samui, Thailand is the perfect island retreat for anyone wanting a mix of beautiful beaches, waterfalls, temples, and modern amenities. In a nutshell, Koh Samui has it all! 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, Koh Samui 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.
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

One of the best things to do in Koh Samui is to get in the water and go snorkeling. 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.
For the first time I actually saw what live coral looked like. I could not comprehend the indescribable amount of colours that I saw beneath me. There were literally millions of brightly coloured fish, coral, anemones and starfish as far as the eye could see. I felt like I was in the Avatar movie.
The neighboring island of Koh Tao is known for its scuba diving, but Samui is also an excellent 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.
Courses are run right off Chaweng, Coral Cove and other beaches with shore diving easy to access. Ang Thong National Marine Park is also considered a great diving destination.
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 at one of the Koh Samui’s top attractions. (even though it isn’t actually located on Koh Samui). The Big Buddha Temple is located on Koh Faan but it is usually the first thing people put on their list to see as it can be seen by air upon arrival.
Visit Grandpa and Grandma Rocks
Hin Ta and Hin Yai (Grandfather and Grandmother Rocks) are one of the more unique things to see on Koh Samui. The male and female genitalia shaped rocks have been a top draw since our first visit to Samui way back in 2003.
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.
Check out the Night Markets
One of our favorite things to do in Thailand is to go shopping. Chiang Mai is famous for its night markets, but in Koh Samui, they have 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.
- Chewang Walking Street Night Market in Bophut- Monday to Thursday and Saturday.
Swim in the Namuang Waterfall
Namuang Waterfal is probably one of the top attractions in Koh Samui. Na Muang 1 is easily accessible just a short walk from the parking lot. Venture up another 100 metres 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”.
Tourists were crowding at the base of the falls, just like I expected. I dodged them and found a tiny almost overgrown footpath on the side of the falls leading up the mountain. As I climbed and climbed the steep little path I reached quite a few smaller but undisturbed waterfalls, each with it’s 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.
I fell in love with my newfound paradise. Two other Canadian guys also stumbled upon my secret place but I was glad to have someone around who appreciated it as much as I did.
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 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.
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.
But you can also walk along the streets to find massage palours or book a fancier massage at one of the higher end hotels. But do yourself a favour, get a massage as much as possible in Thailand. They are so affordable, it is nice to get pampered like royalty on a regular basis
Go for a Hike
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.
Hike to the Secret Buddha Garden to see Buddha sculptures set in a rainforest, hike the Nathon Mountain Trail Ridge, or head up to the Maenam Viewpoint for great views of Nathon and the island.
Secret Buddha Garden
Speaking of Secret Buddha Garden, is a very interesting place to visit. Created in 1976 by a local durian farmer, there are several different depicting different Buddha folklore. You can hike to Secret Buddha Garden or take a 4X4 Jeep Tour.

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. Ang Thong National Park is an archipelago of 42 islands where you can swim in lagoons, relax on pristine beaches and spy sea turtles in its crystal clear waters.
For the ultimate in luxury, book an overnight cruise on a junk boat to experience the islands in private.
Koh Samui is blessed with amazing beaches. Chaweng Beach is Koh Samui’s most popular beach and with good reason. It is one very large stretch of white sand. 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.
Do some snorkeling and kayaking or rent a paddleboard and do some stand up paddle boarding in the calm waters. When the sun goes down, the nightlife begins on Chaweng Beach. Head out to the Green Mango strip for some bar hopping.
Where to Stay on Chaweng Beach
There are an abundance of hotels and apartment rentals on Chewang Beach. Browse the map to find what is right for you.
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.
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 island of Koh Samui 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.
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 food as you learn to prepare meals that you can bring home with you. It’s a fun and interactive way to spend an evening. Book a cooking class details here.
Wat Plai Laem
Another cool temple to see in Koh Samui is Wat Plai Laem. This temple showcases Koh Samui’s Chinese heritage with a giant Guanyin statue dominating the temple grounds. The Goddess Guanyin is believed to be the Goddess of unconditional love
Chaweng Beach is Koh Samui’s most popular beach and with good reason. It is one very large stretch of white sand. 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.
Rent a Scooter – But Be Careful
The island of 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.
Fisherman’s Village in Bophut
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 main section of Fisherman’s Village is Bophut Beach Road which lines the beach. 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.
Lady Boy Cabaret Show
Like the days of La Cage Au Folles here in the 1990s of North America, the Lady Boy Cabaret Shows have become one of the very best things to do in Koh Samui at night. This energetic performance involves lip-synching, dancing, and elaborate costumes.
How to Get to Koh Samui
There are 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. If you are coming from other islands in the south of Thailand, you will have to make your way to Surat Thani. There are also flights from Bangkok to Surat Thani.
From Surat Thani, you will cat the ferry to Koh Samui from the main Surat Thani ferry port at Don Sak
Where is Koh Samui
Koh Samui is located 35 km off the coast of Surat Thani on the Gulf of Thailand. Neighboring islands are Ko Pha-ngan, Ko Tao, and Ko Nang Yuan which can all be reached by longtail boat or ferry.
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 jungles and amazing beaches, maybe I should leave Phuket and move here. Koh Samui will definitely see me again in the near future.
