Looking for an unforgettable adventure in Koh Samui? You’re in the right place. I’ve explored this Thai party island from coast to coast, and the island’s waterfalls are some of my favorite attractions.

Hidden within the lush jungles, these natural wonders offer more than just a cool dip. They provide a thrilling journey, a peaceful retreat, and most importantly, a unique perspective on the island’s beauty.

From the refreshing pools of Hin Lad Waterfall to the exhilarating trek of Na Nuang Waterfall 2, every waterfall experience in Koh Samui is different. And that’s precisely what makes them so special.

That is why I’ve decided to write this article to share my experience with these Koh Samui waterfalls, offer tips, and highlight why they should be on every traveler’s Koh Samui itinerary!

What Are The Best Waterfalls In Koh Samui?

1. Na Muang 1 Waterfalls

Na Muang 1 Waterfall

Located in the heart of Koh Samui, Na Muang 1 Waterfall is undoubtedly one of the most popular waterfalls on the island. This magnificent waterfall cascades into a large pool of water, making it perfect for swimming and cooling off on a hot day.

On any given day, you are probably going to run into a few tourists and locals cooling down in its big and refreshing pool.

Perhaps one of the reasons why it is so popular is how easy it is to get to. Unlike other waterfalls that require a long and often strenuous trek, Na Muang 1 Waterfall is a 2-minute walk from the carpark, which is accessible by car or motorbike.

This makes it a popular destination for families with young children. There is even a rock a few feet high where you can jump off into the pool!

This is definitely the best waterfall in Koh Samui for swimming and relaxing, but note that it can be crowded. There is no entrance fee, but you’ll need to pay for parking.

2. Na Muang 2 Waterfalls

If you are looking for more of a waterfall hike, then head to Na Muang 2 Waterfall. Na Muang 2 Waterfall is situated approximately 1 km from the carpark through a lush jungle path. The trek is not too strenuous, but it can get quite slippery after rain.

After 1 km, you’ll reach the bottom of Na Muang 2 Waterfall. Because of the hike, it is a lot more quiet compared to Waterfall 1. We had the waterfall completely to ourselves when we visited.

Similar to Na Muang 1 Waterfall, there is a small pool where you can swim in and cool off, but the gem of Na Muang 2 Waterfall is not the pool, but the small rock pool above it.

Not only can you get some of the best views of Koh Samui, but the rock pool is quite private, and it is a nice place to relax there with some friends or your partner.

Unfortunately, the rock pool is about a 30-minute hike up. It is quite strenuous, especially in the brutal Thai heat and humidity. But trust me when I say this, it is definitely worth the effort!

3. Hin Lad Waterfall

Located in the southwest part of Koh Samui, Hin Lad Waterfall is probably the second most popular waterfall after Na Nuang.

Getting to the waterfall takes quite a bit of effort. First visitors must park at the Hin Lad Temple, then from there, it is a 1.2-km hike through the thick jungle. For me personally, this only added to the experience! Who doesn’t like hiking through the jungle to find a beautiful waterfall?

Because of the hike, the waterfall is often quiet, and it is big pool is great for relaxing. The waterfall isn’t very high, but it is still impressive, and the surrounding trees make it feel like a hidden oasis.

There are cafes along the way which makes it great for taking breaks and enjoying some refreshments.

When you are visiting Hin Lad Waterfall, I recommend spending some time at the temple as well and soaking up the peaceful and spiritual atmosphere.

4. Wang Sao Thong Waterfall

If you are looking for a hidden waterfall in Koh Samui, Wang Sao Thong is the one. Located just about 10 minutes off the road, reaching this waterfall requires hiking through dense jungle and through many steep inclines.

Because of this, I highly recommend you to wear proper shoes and not just flip flops!

At the end of your hike, you’ll end up at a small waterfall with a nice pool for swimming. This isn’t something that’ll wow you compared to other waterfalls in Koh Samui, but it is a nice and secluded spot in nature that not many people know about.

Because it is a small waterfall, when you visit matters a lot. We highly recommend that you visit during Koh Samui’s rainy season, or just after a few days of rain. Otherwise, you might find the water quite murky and not very pleasant to swim in!

There is a small fee for parking your scooter or car at the start of the hike, but otherwise, it is completely free!

5. Khun Si Waterfall

Khun Si Waterfall is one of my favorite waterfalls in Koh Samui because it combines a beautiful viewpoint with a somewhat decent waterfall.

The trek from the viewpoint to the water only takes about 15 minutes, but don’t underestimate it. The hiking route goes steeply up and down and can be quite challenging, especially after rain.

There are various points where the water cascades downwards, creating numerous small pools where you can take a dip. The main one is sizable, and that is where more visitors get up to.

What I really like about this waterfall is that I can go see the waterfall during the day, then head back to the viewpoint for a drink from the refreshment stand and catch the sunset!

Note: DO NOT follow the path on Google Maps or you’ll go through a much treacherous path with aggressive dogs. ALWAYS start and end your hike at the Khun Si Viewpoint!

6. Ton Ruea Waterfall

Ton Ruea Waterfall, sometimes also known as the Secret Falls, is a series of 2 waterfalls located in the jungles of northern Koh Samui.

It is one of the waterfalls that is a hit or miss depending on how much water there is. During the rainy season, you’ll most likely experience a very powerful waterfall, but close to a small trickle during the dry season.

The reason why Ton Ruea Waterfall isn’t one of my top favorites is because you can’t swim in it. But it does make up for it by having the Tree Bridge Zipline, a really cool suspension bridge, and a nice cafe with a view.

However, mosquitos are especially rampant here for some reason, so don’t forget some insect repellent.

7. Namtok Zong Raue

If you are looking for a peaceful escape into the lush jungle and fruit plantations of Koh Samui, then a visit to Namtok Zong Raue is perfect.

Also known as Song Rua Waterfall, this waterfall certainly isn’t going to “wow” you, but its small modest fall and swimming pool are as close to a natural private oasis as it gets.

There are several levels to the waterfall. We recommend getting to at least the second level because it usually has a bit more water there. Unlike the other waterfalls, most of the route to Namtok Zong Raue is quite well-managed and paved. This makes it perfect for those in Koh Samui with small kids.

After parking your scooter or car, it is only a 10-minute walk to the waterfalls!

This is one of the Koh Samui waterfalls that we recommend visiting after a good day of rain. Also, be sure to bring some snacks and refreshments as there are no cafes or vendors nearby.
