There are lots of luxury resorts, fancy hotels and vacation packages that appeal to the wealthy, but recently the more local, affordable side of Koh Samui is beginning to surface.

Backpacker hostels, street markets, cheap tours and a long list of attractions are starting to pull more young budget travellers to Koh Samui, Thailand.

1) Book a Tour to Ang Thong National Marine Park

This is easily one of the best things to do in Koh Samui, and in the whole Gulf of Thailand.

Ang Thong National Marine Park is an archipelago of 42 islands, each one rugged and unique.

Throughout the park you can find limestone cliffs, rocky caves, thick jungle, lakes and rivers, waterfalls, coral reefs, lagoons, hiking trails and sandy beaches, all connected by the vibrant blue ocean.

Highlights in the park include the Emerald Lake, or “Thale Nai”, a green saltwater lake in the midst of the jungle, Koh Sam Sao, an island with amazing snorkelling, and Koh Mae, an island with a steep hike that leads to a scenic viewpoint.

Luckily, Ang Thong Marine Park is well protected as a national park, so exotic wildlife can thrive and human development never oversteps its boundaries.

Only tour boats that are approved by the government are allowed to enter, so travellers cannot access Ang Thong Marine Park without booking a tour.

But there are lots of reputable tour companies offering affordable and super fun tours around Ang Thong National Marine Park that include snorkelling, kayaking, and relaxing.

BONUS – Booking ahead of time ensures you won’t miss out on the tour, and get the best price too! And just for NOMADasaurus readers, if you use the Klook discount code “NOMADS10” on the website when checking out, you’ll get $10 off your first booking!

2) See a Mummified Monk

Wat Khunaram is a Buddhist temple in Koh Samui famous for its mummified monk.

This sight isn’t for the faint-hearted, as it is literally a dead body on display in a glass case. But it is quite fascinating for those who are interested.

Buddhist monk, Luang Pho Daeng, died in 1973 and his body is now a source of wonder for local Thais and Buddhists in the area.

He died while sitting in a meditative position and his corpse is in surprisingly good shape for someone who died over forty years ago.

Be sure to follow proper dress code when visiting any temples in Thailand (no shoulders or knees showing).

• Location: Na Mueang, Ko Samui District, Surat Thani 84140
• Hours: 7 am to 5 pm, open every day
• Cost: Free

3) Visit the Big Buddha

The Big Buddha should definitely have a place on any list of things to see in Koh Samui.

Formally known as Wat Phra Yai, this Buddhist temple complex is located on a small island off of Koh Samui’s northeastern coast.

The massive golden Buddha sitting at the top of the temple stairs is 12 meters tall and was built in 1972.

If you’re flying into Koh Samui you can sometimes see the giant Buddha from the airplane.

The Wat Phra Yai temple grounds also host a small market with souvenirs, interesting clothes and religious ornaments on sale.

• Location: Big Buddha Beach, off Route 4171, Bophut
• Hours: Open all day, every day
• Cost: Free

4) Indulge in a Thai Massage

Thai massage is an ancient healing practice that is revered all around Thailand.

Though the massage isn’t as relaxing as traditional massages, it is supposed to rejuvenate the body and feel amazing afterwards.

Trained Thai masseuses bend and twist your body into odd positions during a massage, and this gets the blood flowing and soothes as well as strengthens your muscles.

There are plenty of spas all over Koh Samui, so check them out if you feel like treating yourself.

5) Try Stand Up Paddleboarding

With ocean scenery as stunning as Koh Samui, do your best to spend as much time in the water as possible.

For a relaxing and laid-back yet active day in Koh Samui try stand up paddleboarding. (You can book your SUP experience here.)

Paddleboards are heavy and sturdy, so they are easy to balance on even if it’s your first time.

This is a great way to soak in the views and spend quality time with the ocean, and it is a family-friendly activity as well.

Try paddling at sunrise or sunset to beat the heat and see the sky’s natural colours dancing above the water.

BONUS – Booking ahead of time ensures you won’t miss out on the tour, and get the best price too! And just for NOMADasaurus readers, if you use the Klook discount code “NOMADS10” on the website when checking out, you’ll get $10 off your first booking!

6) Laze Away on one of Koh Samui’s Beautiful Beaches

You simply can’t visit Koh Samui without visiting a few of the island’s picturesque beaches.

Chaweng Beach is the most popular place on the island, with tons of Koh Samui attractions and nightlife surrounding the beach.

So if you’re wondering what to do in Koh Samui, hit Chaweng Beach first, then figure the rest out from there.

Lamai Beach is the second most popular beach, and but it is less crowded and much more relaxing than Chaweng Beach.

Coral Cove Beach is lovely for snorkelling and is hidden in a small bay behind a hotel.

Choeng Mon Beach is located on the north of the island near the Big Buddha, and there are lots of nice hotels and beach bars up here.

Lipa Noi Beach is the most kid-friendly of Koh Samui’s beaches, as it has shallow, clear water and barely any coral or rocks.

Pretty much every beach here has velvety white sand and coconut palm trees providing shade, and the water is clear and refreshing everywhere too.

So pick any beach on Koh Samui and you’ll feel like you’re in paradise.

7) Explore the Secret Buddha Garden

The Secret Buddha Garden is one of the most interesting Koh Samui attractions.

Back in 1976, a local farmer named Nim Thongsuk began creating a garden by setting up statues around his land.

Years later, the statues of Buddhas, other deities, animals and random creatures have taken over and the lush jungle gardens provide a nice background to all the artwork.

Spend an hour strolling through the peaceful green forest and admiring all the interesting statues; there is a sense of mystery here at the Secret Buddha Garden that is intriguing.

Some adventure tours around Koh Samui stop at the Secret Buddha Garden as part of their itinerary, though you can also drive on your own.

Even though it is called the SECRET Buddha Garden, this beautiful place has become one of the most famous Koh Samui attractions.

8) Taste Local Food at the Chaweng Night Market

The temple is famous for its statue of Guanyin, the Goddess of Mercy and Compassion.

Bathed in white and sporting 18 arms, the Guanyin statue towers over the temple grounds and the surrounding lake.

Wat Plai Laem is close to the Big Buddha, so you can easily stop by both during your Koh Samui sightseeing.

10) Hike to the Hilltop Temple, Khao Hua Jook Chedi

For a bit of exercise and panoramic views, visit Koh Samui’s hilltop temple known as Khao Hua Jook Chedi.

You’ll have to drive or take a taxi to Khao Hua Jook Chedi as there is no public transport running directly to this attraction.

The mountain on which the temple lies is called Chom Daow Mountain, and there is a shimmering gold pagoda as well as statues and Buddhist artworks in the temple complex.

These two waterfalls are some of the best natural sights in Koh Samui.

And it has a wide natural pool that is perfect for swimming (especially during the rainy season).

Getting to Waterfall Two requires a little climbing, so wear sturdy, waterproof shoes.

12) See the Mysterious Hin Ta and Hin Yai Rocks

Of all the things to do in Koh Samui, this is probably the oddest.

Set on a rocky beach on the island’s southeast coast, the Hin Ta and Hin Yai Rocks are famous because they resemble male and female genitalia.

They are also called the Grandfather’s and Grandmother’s Rocks, and there are a few local myths about how the rocks came to be.

Whether you are interested in the stories behind the landmarks or not, the nearby beaches are beautiful so it is worth stopping at Hin Ta and Hin Yai Rocks.

13) Check out the Guan Yu Shrine

Symbolic of the Chinese culture that has spread throughout Thailand, the Guan Yu Shrine is a powerful landmark in Koh Samui.

There is a 16-meter high statue of Guan Yu, the Chinese God of War and a symbol of courage, loyalty, and bravery.

You probably won’t find too many other tourists here, so you can enjoy a little bit of peace and quiet while reading about the shrine’s history.

If you want to continue your education about Chinese culture after visiting the statue, there are some local Chinese restaurants out front.

• Location: 190/1 Moo 1, Tambon Maret, Koh Samui, Surat Thani 84310

14) Attend a Ladyboy Cabaret

One of the best things to do in Koh Samui, or anywhere in Thailand, is going to a ladyboy cabaret.

Koh Samui’s best location for watching a dazzling ladyboy performance is the Paris Follies Cabaret in Chaweng Beach.

There are three shows every night here, and different dances and songs from all over the world are incorporated into the sets.

So for a night full of song, dance, and charisma, go to the Paris Follies Cabaret and prepare to be entertained by Koh Samui’s best ladyboys.

16) Hike the Elephant Rock near Lamai Beach

Those looking for active things to do in Koh Samui can head to the Elephant Rock, located between Chaweng and Lamai Beach.

This massive rock formation is named “Elephant Rock” simply because it looks like a giant boulder the same size as an Asian Elephant.

You can climb Elephant Rock to get a great aerial view of the surrounding ocean and beaches.

This is a nice outdoorsy activity to do while hanging out near Chaweng or Lamai Beach; just make sure you wear sturdy hiking shoes.

17) Watch a Muay Thai Boxing Match

Muay Thai is a major part of Thai culture that travellers should try to experience in Thailand.

Koh Samui’s best place to watch a Muay Thai boxing match is Chaweng Boxing Stadium, which is also the oldest stadium on the island.

Here you can observe the talented local athletes as they engage in combat, the techniques and tricks of which evolved from the ancient fighting methods of the Siamese Empire.

Chaweng Boxing Stadium even has a program where they take youths off the streets and train them to fight Muay Thai in a safe and secure place.

So fighters you may watch during a match can range from young kids to professional adults, male or female.

This boxing stadium stays true to local traditions and still makes the fights engaging and exciting for tourists.

• Hours: Fights every Tuesday and Friday starting at 9 pm

18) Take a Thai Cooking Class

The food is definitely one of the highlights of travelling through Thailand.

Thai food is so full of flavour and fresh ingredients, and every meal feels like an adventure for your taste buds.

The local cuisine differs slightly depending on which region of Thailand you are in.

So if you’re a true foodie you may want to take a few different Thai cooking classes throughout the country.

Koh Samui has lots of cooking schools that offer full-day tours cooking classes, most of which include a tour of the local market followed by guided instructions for making classic dishes.

This one though is the highest rated, so make sure you book it ahead of time.

The food you prepare yourself may be some of the best you eat in Thailand.

So dedicate at least one day in Koh Samui to a fun Thai cooking class.

19) Marvel at Laem Sor Pagoda

Another one of Koh Samui’s best landmarks, Laem Sor Pagoda is located on a quiet beach far from the popular tourist areas.

Down in the southwest corner of the island, the Laem Sor Pagoda stands tall as part of the Wat Laem Sor temple complex.

The Pagoda appears to be fully coated in gold, though it is actually tiny yellow tiles that give it that glowing appearance.

Near the pagoda is a small forest with a lake and picnic benches, as well as another Pagoda called Khao Chedi, located atop a hill that offers panoramic views.

So there are a few things to do down in this corner of the island, and this area makes a nice escape from the more crowded, touristy parts of Koh Samui.

• Hours: Open all day, every day

20) Go Diving or Snorkeling

The Gulf of Thailand is known for some of the best snorkelling and diving in Southeast Asia.

The waters are crystal clear and the wildlife is colourful and active.

Koh Samui has a few nice snorkelling spots, but the best locations for snorkelling or diving are next to other nearby islands like Koh Tao and Koh Phangan.

Your best option is to book a day tour through a local tourism company, so they can take you around the best snorkelling spots by speedboat.

Koh Tao and Koh Nangyuan are two popular sights for snorkelling or scuba diving, and they can easily be reached by speedboat from Koh Samui.

Experienced certified divers can explore the waters deeply and swim down through coral reefs.

Whereas other travellers can opt for snorkelling, which doesn’t require any certifications and is a bit easier.

Whether scuba diving or snorkelling near the surface, you are sure to spot some exotic fish and sea creatures while exploring the oceans.

Tropical islands offer some of the most majestic sunsets.

Nothing says makes a vacation memorable like watching the sky change colours as the sun slowly slips behind the horizon, with the waves crashing and the palm trees swaying in the breeze.

Some of the best beaches to go watch the sunset are Lipa Noi Beach, Taling Ngam Beach or Nathon Town Beach.

They are all located on the island’s west coast so they face the setting sun.

This side of the island is also far less touristy than the east side, so you’ll most likely have the beach to yourself except for a few locals.

On a similar note, head to any beach on the east side of the island for a spectacular sunrise view!

22) Try a Fruit Carving Class

If you’ve ever been to any sort of fancy hotel or restaurant in Thailand, you may have seen incredible art displays made entirely out of fruit.

The art of fruit carving is a traditional Thai skill that originated in the decoration of events for the Thai royal family.

Fruit carving is more accessible these days, but it is still considered a respectable skill.

You can take a fruit carving class at the Intercontinental where professionals will teach you how to carve beautiful designs into fruit and vegetables.

This is a very hands-on experience, and you are sure to learn a lot about this traditional form of Thai art.
