The island of Koh Samui is famous for it’s picture-perfect tropical paradise beaches with palm fringed soft white sand and calm turquoise waters, and luxury resorts.
But that’s not all Thailand’s second-largest island has to offer, and what draws many people here is the vast and diverse array of things to do in Koh Samui.
It’s the perfect destination to combine a beach holiday with exploring the lush jungle landscapes and the fascinating Thai culutre.
If you’re looking for adventurous activities, unique temples, jungle exploration, island hopping trips and some of the best resorts, spas, food, and nightlife in Thailand – you’ll find it all in Koh Samui!
The Best Things to do in Koh Samui, Thailand
I lived on this fantastic Thai island for a month so I had plenty of time to explore all the different beaches, areas, activities and attractions on Koh Samui.
So, if you’re wondering what to do in Koh Samui and looking for not just the most popular Koh Samui attractions but some lesser-known hidden gems as well, read on!
I’ve divided the article into sections so you can easily find what you’re looking for: beaches, nature and adventure, temples and culture, shopping and food, or even island hopping from Koh Samui – this island has it all!
Go Beach Hopping
Koh Samui has over 40 idyllic beaches so checking out a few different beaches is of course one of the best things to do in Koh Samui. Unless you stay for one month, you won’t have time to visit them all, so here are a few of the most popular beaches in Koh Samui to check out during your stay:
Chaweng Beach – Samui’s best, biggest and busiest beach. There is always a lively atmosphere and plenty to do, from water sports to beach massages. There are many beach clubs, restaurants and bars along the beachfront so it’s a fantastic beach for anyone who gets bored just sunbathing.
Lamai Beach: If Chaweng Beach feels too loud and crowded, head south to Lamai Beach, which is much calmer but not deserted by any means. Lamai beach is a great spot for sunrise and, as most of the beach is lined by palm trees, there are usually some nice shady spots here in the afternoon.
Crystal Beach and Coral Cove: If you are visiting Lamai Beach you should check out Crystal Beach (also known as Silver Beach) and Coral Cove nearby. These picturesque small bays offer a refreshing escape from the crowds with shallow waters and unique rock formations.
Maenam Beach: A long, peaceful stretch of sand in the north, ideal for long beach walks and sunset sessions. As one of the less developed beaches on the island, it ‘s ideal for relaxed beach days.
Lipa Noi Beach: Most of Samui’s popular beaches are on the west side of the island, so if you want to witness a stunning sunset head over to Lipa Noi on the east coast. This secluded beach offers a peaceful escape from the crowds and the best spot to watch the sun dip below the horizon.
Nature and Adventure
Samui’s spectacular scenery extends beyond its stunning beaches so don’t forget to explore inland where you’ll lush jungle, waterfalls, coconut plantations, hiking trails, viewpoints, and even a magic garden. Here are a few must-sees for nature lovers.
Visit an Ethical Elephant Sanctuary
Many tourists who come to Thailand enjoy visiting the elephant sanctuaries and seeing the elephants. However, it’s crucial to visit a sanctuary that is ethical; i.e. does not offer any harmful activities with the elephants like bathing or riding.
One ethical elephant sanctuary on the island is Samui Elephant Sanctuary, which is home to 14 rescued elephants. Here you can feed the elephants, walk alongside them, and observe them as they roam and bathe themselves. This Samui Elephant Sanctuary Tour includes hotel transfers and a buffet lunch and is an unforgettable experience for animal lovers.
See the unique Hin Ta and Hin Yai rocks
Here’s one of the most surprising attractions in Koh Samui – rocks shaped like human genitalia!
Hin Ta and Hin Yai (meaning grandfather and grandmother) are natural rocks that the wind and sea have shaped for centuries and, hilariously, now resemble male and female genitalia. As you can imagine, these unusual rock formations are a very popular photo spot for tourists.
You’ll find them at the southern point of Lamai Beach (here’s the map link) against a stunning coastal backdrop of turquoise waters and crashing waves, making for excellent (and humorous) photo opportunities!
Take a dip at the Na Muang Waterfalls
There are many waterfalls to explore in Koh Samui but Na Muang Waterfall is the most impressive. The site actually consists of two waterfalls – Na Muang 1 and Na Muang 2.
The main waterfall (Na Muang 1) is easily accessible from the parking so it can get quite crowded in the peak season. It’s extremely picturesque due to its 18 meter drop and mesmerizing pool at the base where you can take a refreshing dip. Of course, it’s most impressive during or just after the rainy season.
The second waterfall, Na Muang 2, requires a short hike to reach and is a little tricky to access (wear proper shoes not flip flops!) But it’s well worth it as this fall is much quieter and more secluded with multiple small pools to dip in and great views back over the island.
What’s unique about these two falls is the distinctive purple color the rocks have when water flows over them. This is reflected in their name “Na Muang,” which means “purple face” in Thai.
One thing to be aware of is that there are cobra shows and elephant riding on the approach to the waterfalls. If you love animals don’t support these unethical animal attractions.
The waterfalls are just a 20 minute drive from the next attraction, so it’s well worth combining the two…
Discover Tarnim Magic Garden (Secret Buddha Garden)
One hidden gem you’ll find in the middle of the island is Tarnim Magic Garden (also known as the Secret Buddha Garden.) Located on one of the highest peaks on the island, this private sculpture park is an enchanting site that blends art, nature, and spirituality for a unique experience.
The garden contains numerous statues, sculptures and carvings of Buddhist deities and mythological creatures that give you an interesting insight into Thai culture, religion and spiritualty while also being immersed in nature.
A small stream flows through the garden, creating a truly peaceful and magical ambiance that is perfect for meditation or reflection. The steep hills and bad roads mean it’s not easy to reach so the garden isn’t crowded and feels like a secret hence the nickname ‘Secret Buddha Garden.’
Explore with a Guided Jeep Tour
As some of these offbeat attractions are located up steep hills on bad roads they can be tricky to reach by car or scooter so the best way to explore this part of the island is on a jeep tour.
On this highly rated 4WD Wild Jungle Safari Tour you’ll visit many of the island’s top sights in just one day. The tour includes transport, lunch and stops at 5 of the best things to see in Koh Samui:
- Hin Ta and Hin Yai rocks,
- Na Muang Waterfall,
- Wat Khunaram (the mummified monk temple),
- Tarnim Magic Garden (Secret Buddha Garden)
- And Wat Phra Yai (the Big Buddha temple)
By traveling in a 4X4 army jeep, you’ll reach more spots than by a minivan, and it’s an incredibly fun experience, too!
Admire the island from a viewpoint
For a different perspective of Koh Samui and some great photo opportunities, head to one of the many viewpoints scattered across the island.
The most easily accessible are Lad Koh Viewpoint, on the road between Chaweng and Lamai, and Wat Khao Hua Chuk where a short walk takes you to a pagoda with 360 degree panoramic views over Chaweng and the airport.
If you’re feeling more adventurous, take a fun cable car ride or hike up to Lamai Viewpoint for stunning views and great photos. Or head to the Jungle Club or The Roof Samui where you can soak up the inspiring view from the comfort of a beanbag while enjoying delicious food and drink.
Temples and Cultural Activities
Koh Samui may have developed with a heavy Western influence over the years, but this doesn’t mean it lacks Thai culture – far from it! The island is home to some impressive and unique temples that are well worth visiting.
As with visiting any temples and sacred places in Thailand, you’ll need to remove footwear to enter the temple and dress respectably with your shoulders covered and avoid wearing swimwear, or super short shorts or skirts.
The best temples to visit in Koh Samui include:
Admire the iconic Big Buddha at Wat Phra Yai
The most visited temple in Koh Samui is Wat Phra Yai, which is the home of the golden Big Buddha statue. While it’s not quite as large or impressive as Phuket’s hilltop Big Buddha, it is still one of the top things to see in Koh Samui.
This is because Wat Phra Yai is located on a small rocky island (Koh Fan) that is attached to the mainland by road, creating a sacred atmosphere with panoramic ocean views. It’s also just a few minute’s drive from this noteworthy temple …
See the Unique Statues at Wat Plai Laem
From a giant Buddha to an 18-armed goddess, Wat Plai Laem is famed for its colossal statue of Guanyin, the Goddess of Mercy and Compassion.
But this is not the only impressive sight you’ll find at Wat Plai Laem, there are many others including a giant laughing Buddha, which represents prosperity, abundance, and, of course, happiness, and a beautiful temple that looks like it’s sitting on a pink lotus flower floating on the lake.
Make sure you go inside to admire the stunning murals on the walls of the temple, and if you want to immerse yourself in the local culture while you’re here, you can feed the fish in the temple’s lake, which Buddhists see as an act of ‘making merit.’
Both these famous temples are picturesque, authentic Thai attractions and are free to visit but, if you want to understand more about Thai culutre and Buddhism, then it’s worth taking a guided tour – most of the island tours will visit these temples.
Visit Wat Ratchathammaram (The Red Temple)
Just below Lamai is this unique red temple. Wat Ratchathammaram is less famous than the previous two temples, but it’s just as beautiful with it’s terracotta color, sea views, and intricate sculptures. It’s a small but unique temple that is well worth a quick stop when you are on your way to the next attractions.
Check out the Guan Yu Shrine
Carry on driving south and you won’t miss the Guan Yu shrine with it’s massive 16 meter high statue of Guan Yu, a legendary warrior/ god of war in ancient China.
This unique sight is worth a quick stop to see the beautiful Chinese shrine inside and to get an insight into Chinese culture on Koh Samui. There’s also some authentic Chinese restaurants outside if you are feeling peckish.
See the Mummified Monk at Wat Khunaram
If you like unique attractions, head next to visit the intriguing mummified monk at Wat Khunaram.
Yes, this is a real mummy! The monk, Luang Pho Daeng, passed away in 1973 while in a meditative seated position, and remarkably, his body has been naturally preserved ever since!
The mummified monk is displayed in a glass case at the temple, wearing his orange robes and sunglasses, as a reminder of the transience of human existence – a significant teaching in Buddhism. If you’re interested in spirituality and Buddhism, this is a great place to visit while in Samui.
As Wat Khunaram is close to Na Muang Waterfall, many people combine these two tourist attractions. If you don’t want to drive there yourself or are traveling solo and need photo buddies, I recommend joining the Koh Samui Waterfall And Mummified Monk Temple Tour.
On this tour, you’ll have plenty of time at the waterfalls and at Khunaram temple and will learn many interesting facts and stories about these two sites!
Island Hopping Day Trips from Koh Samui
Some of the best things to do in Koh Samui extend beyond the island itself. Samui’s prime location in the Gulf of Thailand means there are many nearby islands to explore, including a world-famous marine park, and some great snorkeling and scuba diving spots with stunning coral reefs and diverse marine life.
No Koh Samui trip is complete without a bit of island hopping, so here are my favorite Koh Samui island hopping trips:
Discover the Ang Thong Marine Park
Ang Thong Marine Park is a beautiful archipelago of 42 islands northwest of Koh Samui. It is arguably THE best thing to do in Koh Samui because it’s a beautiful tropical paradise and a truly unforgettable experience!
The marine park is a protected area where only two islands are inhabited. On Wua Ta, the main island, there are some basic accommodation options but thanks to its proximity to Samui, a day trip to the island is long enough.
Upon arriving at the marine park, you’ll be greeted by towering limestone cliffs, lush tropical forests, and inviting turquoise waters full of aquatic life. One of the most popular things to do in Ang Thong Marine Park is hiking to the Koh Wua Ta Lap viewpoint, which gives breath taking views over the archipelago.
The Emerald Lake is another must-visit attraction. It’s a hidden saltwater lagoon surrounded by limestone cliffs, and there’s a viewpoint you can climb up to see the surreal green waters.
Most people join a group tour to visit the marine park, but it’s also possible to charter a private long-tail boat (but this will be more expensive.)
This Angthong National Marine Park Day Trip is a popular group tour as you travel by speedboat, meaning you have more time at the park. The excursion includes snorkeling, guided kayaking, and a buffet lunch.
Spend a day (or night) on Koh Phangan
No trip to Samui is complete without a visit the neighboring island of Koh Phangan – it has a totally different vibe from Samui – it is smaller, less developed, and more laid-back.
Koh Phangan is most well known for it’s famous Full Moon Party held every month on Haad Rin Beach. If you want to join in the fun you can get packages like this that transfer you over from Koh Samui to the famous party.
But there’s many different sides to Koh Phangan so it’s also well worth a visit at other times of the month as there are stunning beaches, epic parties on all the time (not just during the full moon period) and plenty more things to do on Koh Phangan to keep you busy.
If you’re into yoga and spirituality, head to Srithanu, the island’s yoga hub. Take a yoga class or join an ecstatic dance workshop or simply head to Zen Beach which has a very hippie vibe, especially at sunset when it’s full of free spirits singing, playing music and doing acro yoga.
You can take a speedboat from Bangrak Pier on Samui, which will get you to Phangan in just 20 minutes or get the ferry from Na Thon which takes about 1 hour. You can book ferry tickets on 12GoAsia.
If you want to see the more exclusive sights of Phangan, I recommend this Koh Phangan Island Full-Day Cruise. You travel by a traditional sailboat (which has a sunbathing deck) and visit many secluded beaches and hidden coves around the island, such as Thong Nai Pan – one of my favorite beaches in Phangan.
Snorkel or Dive at Koh Tao and Koh Nang Yuan
Visiting Koh Tao is another one of the most popular things to do in Thailand and you can take a day trip there from Koh Samui!
Koh Tao is much smaller than Samui and Phangan and has a very chilled island vibe. It’s renowned as one of the world’s best scuba diving destinations because it’s surrounded by vibrant coral reefs teeming with colourful fish and marine life including turtles, sting rays, and whale sharks!
You can explore the underwater world by snorkelling or try scuba diving on Koh Tao. The island is one of the best and most affordable places in the world to do a PADI Open Water course and get certified but note that most courses take 3 – 4 days to complete so it’s not a day trip activity.
If you’re just visiting on a day trip from Koh Samui you can take a ferry, which takes 90 minutes, or a boat tour by speedboat which takes 45 minutes, depending on the sea conditions.
If you want to snorkel in Koh Tao, it’s worth going on an organized boat trip, such as the Koh Tao and Nang Yuan Snorkeling Tour, to make the most out of your day. On this full day trip, you visit various swimming and snorkeling stops around Koh Tao and the nearby Nangyuan island which is also home to one of the most iconic viewpoints in Thailand.
Take a Boat Trip to Pig Island (Koh Madsum)
Another excellent snorkeling spot and unique island to visit near Koh Samui is Koh Madsum. It’s also known as ‘Pig Island’ as it is home to wild pigs, many of which will greet you on the beach!
If you’re wondering how pigs ended up on the island, the story goes that a handful were recused by a local villager and brought to the island, where they have bred and adapted to island life.
You can explore this unique attraction on the Pig Island Snorkeling Tour. On this day trip, you’ll visit Pig Island and the neighboring island, Koh Tan. Here, you’ll have plenty of snorkeling, swimming, and sunbathing opportunities, and, of course, lots of time with the pigs!
Shopping and Foodie Experiences
There’s no shortage of shops and eateries in Koh Samui. For international brands head to Central Samui shopping mall which also has an air-conditioned food court. If you prefer to look for bargains, authentic Thai food and street eats, head to the lively walking streets and night markets.
Stroll through Bophut Fisherman’s Village
The Fisherman’s Village in Bophut was once a thriving fishing community but has now transformed into a lively tourist area full of restaurants, shops, and bars.
What’s cool about Fisherman’s Village is the original rustic wooden shophouses and a traditional fishing boat are still there, but they have been converted into trendy eateries, blending traditional with modern.
The best time to visit is undoubtedly Friday evening when the full Walking Street market is on. You’ll find various Thai and Western food and many unique souvenirs and gifts. It’s a place you shouldn’t miss when visiting Koh Samui.
Enjoy Shopping and Nightlife in Chaweng
Chaweng has several lively night markets and walking streets that are open 6 days a week. Chaweng night market is conveniently located on the lakeside by Central Samui Mall while Chaweng walking street is found behind the Avani Resort.
Being in central Chaweng you can expect a lively atmosphere at these markets. Browse an impressive number of food stalls serving up Thai delights like Pad Thai, papaya salad, mango sticky rice, and coconut ice cream as well as stalls where you can buy cheap clothes, accessories and souvenirs. There is always lots to see here, so it’s well worth a visit when you’re in this part of the island.
And Chaweng’s nightlife is pretty epic, check out lively beach clubs like Ark Beach Club where you can party by the water or head to nearby Soi Mango where you’ll find plenty of lively bars and nightclubs like The Green Mango and the unique Barcade where you can play old arcade games to a lively soundtrack.
Learn To Cook Thai Food
Cooking classes are a popular tourist activity all over Thailand, and there are some fantastic ones in Samui so it’s a great place to learn how to cook all your favorite Thai dishes at home.
This Thai Cooking Class starts with a visit to a local market where you’ll discover the incredible array of exotic Thai herbs, vegetables, and spices. You will then prepare and cook a Thai menu, consisting of 3 classic dishes like Pad Thai or Green Curry, before tucking into your creations!
Other Activities in Koh Samui to Consider
Go Zip Lining!
This is by far one of the most thrilling adventures that Koh Samui offers. The 1,200-meter zip line takes you high into the tree tops, giving you a panoramic view of the jungle beneath you, including the hidden Tan Rua waterfall. This Zip Line Experience will pick you up from your hotel, and it includes a drink at a mountain-top cafe afterward.
Take an exhilarating Quad Bike Tour
Here’s another activity for the adrenaline seekers! On this ATV Quad Bike Safari Tour, you’ll explore the island via a quad bike, navigating through the lush jungles and dirt roads. You can choose between a one or 2-hour tour. I recommend staying for 2 hours as you’ll visit secret waterfalls and an epic mountain viewpoint.
Watch a Live Muay Thai Fight
Muay Thai boxing, Thailand’s national sport, is renowned for its intensity and strategic techniques, and you don’t need to travel to Bangkok to witness the action.
Samui International Stadium has live fight cards three times a week (Tuesday, Friday, & Sunday). Here you can watch both Thai and international professional Muay Thai fighters in action, which is an adrenaline-packed and unforgettable experience.
There’s also numerous Muay Thai classes where you can learn the sport yourself for a fun way to keep fit on holiday – if you prefer something more relaxing there’s yoga classes on the island too.
Relax with a Thai Massage
Another must do in Koh Samui is to relax with a massage. Getting a massage in Thailand is a lot more affordable than it is back home so it’s a great chance to treat yourself.
Most of the luxury resorts have excellent spas, or you could indulge at a luxury day spa like Tamarind Springs or enjoy a cheap massage on the beach or in a budget friendly massage parlour.
As well as the traditional Thai massage many spas also offer other treatments like foot massages, oil massages, facials, body wraps and scrubs.
How to get to and around Koh Samui
As you can see there is no shortage of things to do in Koh Samui, but how do you get to them?
Well, there’s plenty of options. Unlike most other Thai islands, Koh Samui has an airport so the easiest and quickest way to get there is to fly, but you can also take a ferry if you’re on a budget.
Koh Samui Airport (USM) is beautiful but flights are limited to Bangkok Airways and are often more expensive than the mainland airports. A cheaper, but longer, way to reach Samui is to fly to Surat Thani Airport (URT) on the mainland and then take a bus and ferry combo to Koh Samui which takes approximately 4 hours. You can book this easily on 12GoAsia.
Once on the island there are many ways to get around. The cheapest option is to hop in one of the shared songthaews that run between the popular areas and beaches. If you want to get off the beaten track then take a taxi, you can use online apps like Grab or hail a taxi but agree on a price before setting off.
The best way to explore is to take a day away from the beach and either rent a scooter, motorbike or car to explore the island at your own pace, or join a tour that will take you around the highlights. To explore the neighbouring islands you can get a ferry. take boat trip, or join an island hopping tour.
You can find both group tours and private tours on Get your Guide and Viator where you can read reviews to make sure you have the best experience. The best day tours in Koh Samui are:
So now you know what to do in Koh Samui
As you can see, there are endless things to do on Koh Samui, which is why this island is such a popular holiday destination for all kinds of tourists and travelers.
