Updated: 30 October, 2024

What to do in Koh Samui: must-visit spots, top beaches, dining recommendations, transportation tips, and more!

Situated in the Gulf of Thailand, Koh Samui might be overshadowed by its more famous sister islands among tourists.

Koh Tao, with its rich marine life, is a diver's paradise, and Koh Phangan is renowned for its zen atmosphere, offering yoga, meditation, and the famous Full Moon Party.

However, Koh Samui is the most significant island and the first to be populated. In the 1980s, it was already receiving tourists, even before Koh Tao was inhabited.

It's also the only one with an airport offering direct flights from Bangkok, Phuket, Chiang Mai, and various international destinations.

Koh Samui is an island of great appeal, featuring crystal-clear beaches where you can chill-out and water activities, abundant natural areas, and a wide array of excellent restaurants and nightlife.

Although it has a diverse range of luxury resorts and boutique hotels that attract family and affluent tourists, there are accommodations for every budget.

In this article I tell you the best things to do in Koh Samui

What to do in Koh Samui?

1.- Big Buddha

The Big Buddha is the island's most iconic spot, featuring an impressive 12-meter tall Buddha sculpture and ranking among the top things to do in Koh Samui.

Located in the northwest area of the island at Wat Phra Yai, it offers a beautiful panoramic view of the sea, perfect for catching sunsets.

If you're lucky, you might even witness a low-flying plane passing by the area. Entrance to the temple is free.

2.- Wat Plai Laem

This is a temple complex located just over a kilometer from Big Buddha, and the entrance is free.

It's quite an interesting place with remarkable sculptures, the main and most striking one being a large statue with 18 arms representing Guanyin, the goddess of Mercy and Compassion.

Another noteworthy sculpture is the one known as the "Chinese Buddha," the chubby, smiling figure. Adding to the beauty of the place, the main temple and these impressive statues are situated over the lake.

The lake is home to some turtles and enormous carp that you can feed; there are machines selling fish food for 10 bahts. According to the Thais, feeding the fish brings good luck.

You can explore this site with a guide, with this tour of Koh Samui to visit the most iconic places. 😍

3.- Bophut Fisherman's Village

This fisherman's village is a place that's definitely worth a visit for its food stalls. As you might expect, one of the main ingredients is fish and seafood that's incredibly fresh.

If you head to the pier area early in the morning or late in the afternoon, you can see the fishermen arriving with the day's catch.

The market is perfect for a delicious and reasonably priced dinner.

Although Koh Samui has some very good restaurants, for me, this was the best culinary experience on the island, especially at the night market right in front of the fisherman's market.

4.- Na Mueang 1 and 2 Waterfalls

In Koh Samui, you'll find several waterfalls offering a chance for a short hike and a refreshing dip.

Among them, Namtok Na Mueang, where "namtok" means "waterfall," stands out for its purple-hued rocks.

Located on the east side of the island, the park entrance is free.

Na Mueang 1, the larger and more accessible waterfall, is reachable by motorcycle with a short 100-meter walk.

On the other hand, Na Mueang 2 requires about a half-hour walk on a trail, slightly slippery in the rainy season but manageable with moderate fitness.

Although smaller, Na Mueang 2 is equally beautiful, and it tends to be less crowded.

Keep in mind that during the dry season, the waterfalls may not be as spectacular, and there's a chance they might be dry.

What to take to visit the waterfalls?

If you decide to visit, pack your swimsuit for a refreshing dip. Consider bringing water shoes like this one in the link, it will also come in handy because the rocks can be slippery.

It's also a good idea to have some snacks and water with you.

A great way to explore is by joining this private tour of Koh Samui, covering the Big Buddha and waterfalls, and it comes at a reasonable price.

5.- Overlap Stone Viewpoint

This viewpoint offers breathtaking views of the eastern part of the island and is just a 5-minute motorbike ride from Lamai Beach.

The Overlap Stone is a massive rock standing vertically on the edge of the viewpoint.

The small bridge leading to the rock is also quite beautiful but not suitable for those with a fear of heights.

You can check it out in the video listed below; it's the second one.

How to get there?

The climb is quite steep, and you'll need a powerful scooter, especially if there are two of you.

Another option is to do it like I did and walk up. ✌😅

The road is paved but requires good physical condition because it's very steep. Bring water as you'll need it. After that, accessing the overhanging rock is easy.

If you go up with a scooter, before reaching the viewpoint, there are signs warning that it's dangerous to go further. They make you park and charge 20 bahts (0.52 euros / 0.57 USD) for parking.

Then, there's a good stretch of uphill walking. However, it's just an excuse for charging, as locals continue on the road with their scooters or cars, and the path is not that bad.

Price for Overlap Stone

The viewpoint is next to an abandoned building, and there's always someone there charging 20 bahts for access. Many tourists complain, and I even saw someone leave without paying, and, of course, without being able to enjoy the views.

It's clear that these people aren't the owners of the place, but considering the small fee and the effort it took to climb up, I preferred to pay and enjoy the wonderful views, which are well worth it.

6.- Best Beaches in Koh Samui and Snorkelling

Koh Samui boasts a diverse range of beaches for unwinding, and you might find some nearly deserted. My personal favorites are on the island's east side, and here they are:

1. Lamai beach: The second busiest beach on the island and one of the most popular, and rightfully so—it's stunning. A long stretch of fine sand and crystal-clear water.
2. Chaweng beach: Located next to the main town on the island, offering everything from water activities to restaurants. While certain areas can be crowded, with 7 km of beach, it's not difficult to find quieter spots.
3. Bo Phut beach: Situated in the northern part, near the Fisherman’s Village, it's a beautiful beach with crystal-clear water, ideal for relaxation.
4. Cristal beach: A smaller beach that, in my opinion, ranks among the best in Koh Samui.
5. Coral beach: Smaller than the typical island beaches, it features an interesting coral reef on the right side of the beach.

🤿 Snorkeling in Kok Samui

During my first visit to Koh Samui, I headed to Coral Beach based on recommendations for the best snorkeling spot on the island.

However, it left me somewhat unimpressed, perhaps because I was living in Koh Tao at the time.

While it's considered the top snorkeling location on the island with some coral and fish, other areas around the island may have even less to offer underwater.

A more rewarding option is to explore the Ang Thong Marine Park, as mentioned below.

7.- Pig Island

To the south of Koh Samui, there are two tiny islands, with the smaller known as Koh Mat Sum or Pig Island due to its adorable pig inhabitants.

The beach is stunning and absolutely worth visiting. You can reach it through budget-friendly excursions like the one I took, which includes lunch, pick-up at the hotel, transportation and kayaking.

This excursion is quite popular, and it also takes you to another beautiful spot, Coral Island.

8.- Grandfather and Grandmother Rock (Hin Ta Hin Yai)

One of the most unique visits to Koh Samui is Hin Ta Hin Yai, which are rocks in the shape of male and female genitalia.

Located near Lamai Beach, it's a picturesque spot by the sea that's definitely worth a visit if you're in the area.

Locals often believe that these Grandfather and Grandmother Rocks bring good luck in matters of fertility, making it a popular stop for those looking to start a family.

Check out this playlist for views of the rocks, Overlap Stone, a Koh Samui beach, and a fire show.

9.- Sunset in Koh Samui

For a stunning sunset in Koh Samui, head to the west side of the island—it's less crowded and has a more authentic feel.

Another fantastic option is the beachside bars at BoPhut, offering a great atmosphere and an ideal spot to witness the breathtaking Koh Samui sunset. 😍

10. Nightlife

Koh Samui's nightlife is vibrant and diverse. Here are some suggestions for your evenings:

• Fire Shows: Head to the beachfront bars in Chaweng for a lively night out. Enjoy a drink while watching captivating fire performances. You can also catch similar shows on Lamai Beach.
• Ladyboys Cabaret: If you're a fan of cabaret shows, explore the bars around Chaweng offering entertaining ladyboy performances. Paris Follies Cabaret is a well-known spot with fabulous costumes. Check out their Facebook page for more details.

11.- Excursion to Ang Thong

One of the must-see spots in Ko Samui is the Ang Thong National Marine Park.

This park, comprised of several islands, offers some of the most breathtaking scenery you can find.

Since there are no regular ferry services to the park, your best bet is to charter a private boat. This allows you the flexibility to explore the islands at your own pace and stay overnight in the Ang Thong Marine National Park.

Alternatively, you can opt for a guided tour, which is convenient and also more budget-friendly.

The tour package includes speedy boat transportation, lunch, and snorkeling gear.

During the tour, you'll make stops for snorkeling, witness the stunning emerald lagoon, and ascend to a viewpoint boasting breathtaking panoramic views of all the islands.

There's also a more economical option with a slower boat.

I suggest taking the speedboat, as I did, because it allows you more time to enjoy the marine park. You can check availability and make a reservation below.

12.- Sailing trip in Koh Samui

If you love being on the water, renting a boat in Koh Samui is a fantastic way to explore the beautiful surroundings.

For boat rentals in Thailand, I recommend using this platform, which partners with reputable companies offering well-maintained boats.

If you're traveling with family or a group, the cost per person is quite reasonable—I've even found it for less than 250 euros / 272 USD.

It's a great deal for a luxurious experience in the Gulf of Thailand.

• Quad Safari: Dive into Koh Samui's lush jungle landscapes, complete with waterfalls and streams, on an exhilarating quad safari. Book your Koh Samui quad safari here.
• Jet Ski Rental: Experience the thrill of jet skiing, a fun and exciting water activity. Consider taking a jet ski tour around Koh Samui for an unforgettable adventure.

14. Koh Tao and Koh Nang Yuan

If you're heading to Koh Samui, make sure to spend a day exploring Koh Tao, known for its rich marine life—a diver's and snorkeler's paradise

In Koh Tao, you can swim alongside giant turtles and harmless reef sharks, along with other equally fascinating species.

Right next to Koh Tao is another small island, Koh Nang Yuan, which might not ring a bell by name, but you've probably seen pictures like the one below from its viewpoint—one of Thailand's most iconic postcards.

Additionally, one of its beaches is teeming with corals and fish, known as the Japanese Garden.

To visit Koh Tao, you can take a ferry and stay for several days.

Alternatively, a convenient option is to join this full-day speedboat excursion to Koh Tao and Koh Nang Yuan , including multiple snorkeling stops, a visit to Koh Nang Yuan, and a delicious lunch.

Where to Eat in Koh Samui?

If you're a food lover looking to dive into the incredible world of Thai cuisine, Koh Samui is the place to be.

The island has a variety of restaurants to fit every budget.

What makes the food scene even more exciting is the lively community from the Isan region in northeastern Thailand, known for its amazing dishes.

And let's not forget the influence of the Burmese, who are a significant part of Thailand's workforce. They bring mouthwatering dishes to the tables of the Gulf of Thailand islands.

Below, I've put together a list of some of the best restaurants in Koh Samui, ranging from budget-friendly to moderately priced.

I've left out the pricier options—after all, high-end restaurants are expected to be good, and Koh Samui has plenty of those. 😉

Best Affordable Eateries in Koh Samui:

• Fisherman's Village Night Market, Bophut: This gem offers delectable Thai treats at great prices. It's not as crowded as Chaweng's night market, maintaining that authentic feel.
• Lamai Night Plaza: A quaint and authentic night market with a family-friendly vibe, offering reasonably priced dishes.
• Super Chef Restaurant: With a primarily Thai menu and a touch of Asian and international flavors, this spot is a must-try. Don't miss out on their fresh seafood at affordable prices.
• Bao Bao Cafe & Asian Eatery: Serving tasty Asian fusion at a reasonable cost, especially their mouthwatering baos. They've got options for both vegetarians and vegans.
• Malee Kitchen Samui: A mid-range restaurant with exquisite cuisine; their curries and pad thai are among the stars on the menu.
• Cafe 69: My personal favorite on the island, offering beautifully presented Thai dishes with even better flavors. It's a mid-priced spot with vegetarian and vegan options.
• Treehouse Silent Beach Restaurant: Delicious Thai menu, great service, and the beachfront location make it perfect for a special dinner at a moderate price.

Places to Avoid in Koh Samui

If you can, I'd suggest staying away from attractions involving animals.

In Koh Samui, the treatment of elephants is pretty rough, and it's even worse for tigers, which are drugged for people to take photos with them.

Remember, if an animal is doing something it wouldn't do in the wild, it's not a good sign. To make them perform, they often endure a lot of punishment or, worse, they are drugged.

Best Season to Visit Koh Samui

The best months to travel to Koh Samui are from January to April, during the dry season.

While there are occasional rainy days from May to September, it's usually short-lived, making these months still suitable for travel.

If you're planning a trip to Thailand in July or August, this area of the country is a solid option. That's why I included it in this Thailand Road Trip: 14 and 21 Days Itinerary.

October and November are the least ideal months for a visit to Koh Samui due to the stronger monsoon in that region of Thailand. Check the table below for annual precipitation details.

Temperatures on this island are pretty steady, peaking from April to June, with May taking the crown as the hottest month.

As for the minimum temperature, it usually hovers around 25 degrees on average. If you fancy nights with just the right coolness for a good sleep, I'd recommend January to March as the prime months.

Take a glance at the table below for a breakdown of the average annual maximum and minimum temperatures:

How to get to Koh Samui?

From Bangkok, Chiang Mai and Phuket

The quickest way to reach Koh Samui from Bangkok, Chiang Mai, or other key locations in the country is by taking a flight, although it might not always be the most budget-friendly option.

Koh Samui has its own international airport, and it's worth noting that flights to this airport can be on the pricier side due to it being privately owned by Bangkok Airways.

So, if you're looking to save time and prefer the convenience of air travel, I suggest booking your flights in advance. While it doesn't guarantee rock-bottom prices, it should secure you a more reasonable fare.

From Surat Thani, Koh Phanghan, Koh Tao and Chumphon

Another way to get to Koh Samui is by taking ferries and speedboats that connect with other islands and the mainland. On one side, it links up with Chumphon, and on the other, with Surat Thani.

To explore all transportation options, I recommend this website where you can check the prices and book all transportation (flights, train, bus, ferry).

How to get from Koh Samui airport?

If you're flying into Koh Samui for your vacation, here are your options to get to your hotel:

• Taxi: Like at any airport, you can hop in a taxi, but be aware that taxi fares in Koh Samui are on the higher side.
• Transfer:For a hassle-free and budget-friendly choice, consider booking this transfer from Koh Samui airport to the hotel. They'll be there at the airport with a sign bearing your name.

How to get around Koh Samui?

Koh Samui is Thailand's third-largest island, but it's still relatively small, covering an area of 228.7 km².

Driving

When it comes to getting around, you've got a few options, but personally, I'd recommend snagging a scooter or a car. It's budget-friendly and gives you the freedom to explore at your own pace.

If you're thinking about renting a car in Thailand, check out this searcher, where I've found cars to rent in Koh Samui for under 20 euros / 22 USD a day.

Renting a scooter is a breeze; you'll find rental spots all over the place.

👍 Friend's tip: If you're going for a scooter, it's smart to compare prices. They can vary quite a bit from one spot to another. And you may be interested in this guide on How to Rent and Drive a Scooter in Thailand.

Songthaew and Taxis

You can also hop on the affordable shared trucks, known as songthaews, though they might not cover all parts of the island.

The other alternative is taxis and you will have to negotiate the price. If you dare and travel alone you can go with a motorcycle taxi which is much cheaper.

Bicycle

If you enjoy challenges and want to break a little sweat, a great alternative is renting a bike.

I rented an electric bike (I cheated a bit, haha) from E-Revolution, you can find them on Google Maps.

They have excellent electric bikes that ride really well. The 24-hour rental cost me 250 bahts (6.52 euros / 7.11 USD), including a helmet and a chain. They also offer regular bikes that are more budget-friendly.

Where to Stay in Koh Samui?

Koh Samui tends to cater to those with a bit more spending power, standing out for its luxurious resorts. The interesting part? Many of them are surprisingly more affordable than hotels in Europe or the US.

But fear not, Koh Samui has a range of accommodations to suit all tastes and wallets. Here's a rundown of the top picks for hotels in Koh Samui:

• Luxury: Look no further than Centara Reserve Samui for the crème de la crème of resorts on the island. It flaunts exquisite design in rooms and outdoor spaces, generous pools, and direct beach access.

How Many Days to Spend in Koh Samui?

Koh Samui is a decent-sized island with lots of activities and interesting spots to explore, so I'd recommend setting aside at least 4 days.

But if you're short on time, here are some itinerary ideas for 1, 2, and 3 days on Koh Samui:
