The Big Buddha is a must see

10 Amazing Things To Do In Koh Samui

Visit the Big Buddha of Wat Phra Yai Temple 

One of the funny things about Buddhas in Thailand is that almost every city claims they have a “big Buddha.” This will leave you wondering if they are in competition with each other. But, the Big Buddha in Koh Samui is one of the focal points of the island and well worth a visit (and genuinely is a VERY big Buddha). 

It’s a touch of Thai culture on an otherwise westernized (but beautiful) island. What’s really cool about the Big Buddha on Koh Samui is how colorful the stairs and surroundings are with the backdrop of the pure gold Buddha. Built in 1972, this has been one of the star attractions in Koh Samui for a while now. It makes for a great photo opportunity – visiting really is one of the things to do in Koh Samui.

Big Buddha is located at Wat Phra Yai Temple and is best visited either early in the morning when it opens, or just before closing to avoid mass crowds.

TIP: Don’t forget you’ll need to cover your knees and shoulders when visiting this temple.

Entrance is free, which makes it one of the great things to do in Koh Samui if you’re on a budget. 

Rent a moped and drive around the island 

Since Koh Samui is a relatively small island, it’s super easy to explore and that’s exactly what you should do! There are countless beautiful beaches across the island and the best way to explore them all is by renting out a moped and driving – this is definitely one of the things to do in Koh Samui. 

There is a ring road around the island that’s easy to follow and you can do this route in a couple of hours. This includes stops at random viewpoints and beautiful beaches you may discover along the way. The ring road is 51 km long and goes though all the major towns on the island.

PRACTICAL INFORMATION: Moped rental is cheap in Koh Samui and costs around 150-200 Baht per day (that’s $5 to $6 USD).

Hang out at the beach

There is little doubt that one of the top things to do in Koh Samui is hanging at the beach. The island is packed with places where you can spend the day basking in the sun and enjoying the clear waters. 

Among the best beaches in Koh Samui it is worth mentioning Lamai, the second biggest beach on the island; Silver Beach; Maenam Beach and Samrong Beach. Chaweng is the closest beach to the airport and the most crowded, but it still remains very beautiful.

Relax at Grandfather’s & Grandmother Rocks 

I know what you’re thinking … “rocks, really?!” 

But as far as unique spots and rock formations go, this is a really beautiful spot (and a slightly funny genital shape). It is a gorgeous place for a peaceful and beautiful lunch in the sunshine. It’s also possible to relax in the water here too. The rocks also offer amazing views! 

It’s easy to reach this spot on a moped. This may be one of the more random things to do in Koh Samui, but you should definitely keep it on your itinerary.

Experience Koh Samui nightlife

When people think of nightlife in Thailand, they often think of Koh Phangan (for its famous Full Moon Party), Phuket or Pattaya. Don’t overlook the parties of Koh Samui! Koh Samui is home to some of the best nightlife in Thailand. Chaweng beach is the party central of Koh Samui and a great place to start your night. 

If you’re traveling solo and want to meet some other travelers, one of the best things to do in Koh Samui is a bar crawl. A great way to meet others and have fun. 

The island is also home to some really cool beach clubs as well if you prefer to start the fun earlier and enjoy an epic sunset. I suggest Nikki Beach Resort. You’ll see signs for it all over the island and it’s highly rated! 

Go on a hike

The first thing that comes to mind when thinking of islands in Thailand is the amazing beaches, but hiking is actually one of the most fun things to do in Koh Samui and there are several good trails that you can walk – some easy, that go to beautiful waterfalls, and others more challenging leading to viewpoints where you can enjoy breathtaking views. 

The only issue with hiking in Koh Samui is that it is hot and humid, so if you intend to hike make it a point to set out nice and early. I also don’t recommend hiking alone – there are plenty of organized hikes you can join. Enquire with your accommodation. 

Make sure to read my post “Why Hiking Alone Is A Bad Idea.”

Spend a day in Ang Thong Marine Park

One of the best day trips from Koh Samui is to Ang Thong Marine Park – it’s the kind of place where you can relax at gorgeous, pristine beaches; snorkel in crystal clear waters, and simply just relax on the boat. The islands of the marine park are the perfect backdrop for stunning photos. Tours usually go to Emerald Lagoon too. 

These are the best day trips to Ang Thong Marine Park:

The walk to the waterfalls

Discover the beautiful Namuang Waterfall (1 & 2)

Like many of the best spots in Thailand, Koh Samui has some pretty cool waterfalls on offer, with the most famous being Namuang Waterfall. When you go to visit, you’ll discover there are two levels. The first is super easy to access from the carpark and you’ll be there within a couple of minutes. You can swim and chill here for hours under the intense Thai sunshine, or you can take the challenge of reaching falls number 2 – it’s actually one of the most fun things to do in Koh Samui.

This requires a bit of a hike which typically takes around 30 minutes to the top. It’s quite steep and you just need to follow the steps and ropes that lead to the top. You’ll see others on your route, so you can ask them to point you in the right direction if you feel lost.

TIP: Remember that the heat can be intense, so you’ll need to bring plenty of water (but there is a small shop at the base of Namuang waterfall 2).

When you reach the top you’ll be rewarded with two beautiful pools which overlook the jungle. Now it’s time to relax and enjoy the amazing views. 

TIP: I suggest you start this hike earlier in the day, so you don’t get caught in the intense heat and you’re also more likely to have the spot all to yourself (at least for a bit!) 

PRACTICAL INFORMATION: Entrance to the waterfalls is free, but you do pay for parking. This ranges from 20 Baht to 60 Baht ($0.60 to $1.80 USD)  depending on whether you have a moped or a car.

If you don’t feel confident visiting Namuang waterfall on your own, then you can opt for a tour. You’ll see them advertised throughout the island. Alternatively, you can book a guided tour online. These are some good options:

Other waterfalls on the island you can visit include Hin Lat Waterfall and Tarnim & Magic Garden.

Take a day trip to Koh Tao

There is plenty to do in Koh Samui, but in case you want to explore one of the nearby islands, you may want to go on an easy day trip to Koh Tao, thought to be a fantastic place for snorkeling, diving and other water sports. Should you want to book a guided trip to Koh Tao, you can do so here or here

Learn how to cook Thai food

Mastering the art of Thai food may take a long time, but a cooking class is definitely one of the most fun things to do in Koh Samui and you will surely find several ones to suit your needs. Cooking classes usually begin with a trip to a local market to get fresh ingredients, and at the end you will be eating what you prepared. It’s a fun way to get to know a bit more of the local way of life and culture through food. 

This cooking class comes highly recommended – it runs in the morning, in time for lunch time, and in the evening, for dinner.

Practical Information To Plan Your Trip To Koh Samui

Where to stay in Koh Samui

Among the best things to do in Koh Samui there is relaxing at a fabulous hotel. The island has no shortage of places to stay for all budgets and tastes. This is a brief selection:

Getting to Koh Samui

As said at the beginning of this post, Koh Samui has its own airport with easy connections to Bangkok, so it is very easy to reach. You can also get there from the nearby islands and even from Bangkok by boat. You can get your boat transfer from Bangkok here. For a quick and easy airport transfer directly to your hotel, you can click here.  

Getting around Koh Samui 

To get between all the amazing attractions of Koh Samui, you have four main options, highlighted below.

Moped

As mentioned before, the best way to get around the island and to see all the awesome Koh Samui attractions is to rent a moped. You can rent one for around 150-200 Thai Baht daily (but if you’re renting for a longer period of time you can usually negotiate a great deal!). Don’t drive without a helmet and do not drink and drive either. If you’re not confident on a moped, then don’t worry, there are other ways to get around the island. 

Ride the Songthaew

This is basically like an open air minibus form of transportation. It’s a pick-up truck that has two back benches that typically fit around 8-10 adults (prepared to be squeezed when it’s busy). They usually have luggage racks on the top too so they’re a good budget option for transport to the airport or ferry terminal.

Songthaews are available all around the ring route of the island, so you can hop on and off as you wish. To indicate you want to get off, just ring the bell! It’s best to negotiate a price before you go on, but it’s always very cheap. 

Rent a car

If you don’t feel confident on a moped, but like to drive, then you can rent a car typically for a great price on the island. Again, since the roads are pretty self explanatory, driving shouldn’t be any more or less complicated than a moped. 

Taxis

Taxis are also available all over Koh Samui. These are a good option in the evenings if you plan on catching the sunset with a few cocktails. You can negotiate a deal with the taxi driver, but being foreign, it’s natural you’re going to be charged a little bit extra.

When to visit Koh Samui

Koh Samui is best visited between December and April – that’s when you will get the best weather, with sunny days that will mostly be dry. It’s definitely cheaper to visit in the shoulder season, in September and October. May and June are sunny with occasional showers. 

How long do I need in Koh Samui?

I spent 3 nights on Koh Samui and felt this was a perfect amount of time to really get a taste of what the island has to offer. If you are looking for a holiday style visit, then you could easily spend a week or more relaxing on the various beaches whilst sipping on cocktails, but if you’re just island hopping the Thai islands in general, then 3 nights is a great amount. 

For 3 nights, I would suggest an itinerary like this:

  • Day 1: Visit Big Buddha then stop at some of the beautiful beaches for sunset (perhaps Samrong Beach) 
  • Day 2: Chase the beautiful waterfalls of Koh Samui 
  • Day 3: Check out the beach clubs then sample the epic nightlife 
  • Final day: Relax your sore head on some more of the beautiful beaches before your departure

After your visit to Koh Samui, you’re in a great position to visit the nearby islands of Koh Phangan and Koh Tao. The former is famous for its parties, but is actually quite beautiful and quiet outside of the party scene, and Koh Tao is famous for its snorkeling opportunities.
