Arriving on Koh Tao feels like stepping into one of those places you’ve seen on the postcards but never quite believed could look that good in real life. The small island in Southern Thailand has Crystal clear waters, quiet bays tucked between jungle-covered hills, and just enough development to make things easy without ruining the vibe.
During my time on the island, I spent most days doing exactly what you’d expect, beach hopping, snorkelling, jumping off big boulders into the water, and trying to find the next spot that somehow topped the last one.
The island might be small, but the variety of beaches is what makes it stand out. And if you know where to go, you can easily avoid the busier areas and find stretches of sand that feel almost untouched.
To help you plan your time properly, I’ve put together a list of the best quiet beaches in Koh Tao that are actually worth your time.
Whilst the island has plenty of other things to do, I can spend hours exploring the waters and all the life it has. So if you’re like me this list will keep you occupied for your whole time on Koh Tao.
These beaches are mostly based around the southern and eastern shores of Koh Tao. Here you’ll find some of the island’s quietest spots and some of the best places to stay in Koh Tao. If you’re planning on exploring them and staying away from the busier areas, it’s worth booking your accommodation on this side of the island.
These are some of the best quiet beaches in Koh Tao if you’re looking to avoid the crowds and experience a more relaxed side of the island.

Map of Quiet Koh Tao Beaches
Haad Sai Daeng
Haad Sai Daeng is one of Koh Tao’s quieter beaches that somehow still flies under the radar.
The beach itself is small and slightly more rugged, with a mix of sand and rock, but that’s exactly what gives it its charm. It feels more raw and untouched compared to some of the more polished bays on the island.
Where it really stands out is the snorkelling. The water here is incredibly clear, and because it’s less busy than nearby bays, it often feels like you’ve got the whole place to yourself. There’s a good chance of spotting turtles around this area, especially if you head out a little further from shore.
There are a couple of low-key resorts and restaurants nearby, but overall it keeps a very relaxed, quiet atmosphere.
Best for: quiet snorkelling & fewer crowds
Tanote Bay
On the east coast of Koh Tao, Tanote Bay offers something a little different. It feels more rugged and less polished than the west side, but that’s part of the appeal.
The bay is known for its deep, clear water and snorkelling, with a variety of marine life just offshore. One of the standout features here is the large rock just off the beach that people climb up and jump from — not for everyone, but if you’re into that sort of thing, it’s a fun addition.
The climb up tot he top is via a precarious rope but if you fancy it there’s about a 6m jump off the other side into the crystal clear waters teaming with sea life.
Because it’s on the east side, the sea conditions can be a bit more variable, but on a calm day it’s one of the best places to spend a few hours.
It’s also noticeably quieter than the more popular beaches, which gives it a more laid-back, slightly off-the-beaten-path feel.
Best for: snorkelling & jumping spots
Ao Leuk Bay
Ao Leuk is probably the closest thing Koh Tao has to a “perfect” all-round beach. It’s got everything — soft sand, clear shallow water, and some of the best snorkelling on the island.
The bay is sheltered, which keeps the water calm and ideal for swimming. It’s also one of the best spots for beginner snorkellers, as you don’t need to go far from shore to see plenty of fish and coral.
Despite being one of the most beautiful beaches in Koh Tao, it never feels overcrowded. There are a couple of small restaurants and places to rent snorkelling gear, but it still keeps that natural, relaxed vibe.
If you only have time to visit a few beaches on the island, Ao Leuk should definitely be one of them.
Best for: swimming & beginner snorkelling
Sai Nuan Beach
Sai Nuan is one of those places that feels like a proper hidden gem. Made up of two small beaches connected by a short coastal path, it’s tucked away on the south-west side of the island and doesn’t see nearly as many visitors.
Getting here takes a bit more effort, but that’s what keeps it so peaceful. Once you arrive, you’ll find calm water, soft sand and a quiet atmosphere that’s hard to beat.
There’s a small beach bar/restaurant where you can grab food and drinks, but aside from that, it’s all about switching off and enjoying the surroundings.
It’s the kind of place you come to for a few hours and end up staying most of the day.
Best for: seclusion & chilled vibes
June Juea Bay
June Juea Bay is one of the quietest beaches on Koh Tao, and it really feels like you’ve stepped away from everything else on the island.
Tucked away on the south-west coast, it’s a small, peaceful bay with clear water, a mix of sand and rocks, and hardly any foot traffic compared to the more well-known spots. It’s the kind of place where you can sit for a while and not hear much more than the water and the odd longtail boat passing by.
There are only a couple of places to stay and eat here, which helps keep the atmosphere slow and relaxed. It’s not the kind of beach you come to for activities — it’s more about switching off and enjoying the setting.
Snorkelling can be decent around the rocks, especially on calm days, but the real draw is just how quiet it is.
If you’re looking to escape the busier parts of Koh Tao entirely, this is one of the best places to do it.
Best for: total peace & off-the-beaten-path feel
Chalok Baan Kao
Located in the south of Koh Tao, Chalok Baan Kao has a completely different feel to the busier parts of the island. It’s quieter, more local, and a bit more spread out.
The beach itself is long and peaceful, with calm water and fewer crowds. It’s a popular area for longer stays, especially if you’re diving or just want a slower pace.
You won’t find the same level of nightlife here, but that’s exactly the point. Instead, you get relaxed beach bars, local restaurants and a more authentic feel to the island.
It’s also a great base if you want to explore the quieter southern beaches nearby.
Best for: laid-back stays & local feel
Bonus: Laem Thian (For the Adventurous)
Laem Thian isn’t your typical beach, and it’s definitely not for everyone. But if you’re looking for somewhere that feels completely untouched, this is about as remote as Koh Tao gets.
Getting here is part of the experience. It takes around an hour to hike through the jungle from the Sairee side, with a mix of steep sections, dirt tracks and no real signage along the way.
It’s not overly technical, but it’s enough effort that most people don’t bother, which is exactly why it stays so quiet.
When you arrive, you’re met with a small bay, clear water, and the remains of an old abandoned resort slowly being taken over by the jungle. The buildings are crumbling, overgrown, and give the whole place a slightly surreal, almost eerie feel.
That said, this is where a bit of caution is needed.
The old structures aren’t maintained, with broken concrete, exposed edges, and areas that aren’t safe to walk through. There can also be broken glass and debris around parts of the site, so it’s not somewhere to wander around carelessly.
If you do make the effort to get here though, the payoff is huge. You’ll likely have the place almost entirely to yourself, with calm water, great snorkelling, and a side of Koh Tao that feels completely different from the rest of the island.
It’s less about the beach itself and more about the overall experience.
How to get to Laem Thian:
You can walk through the jungle from the eastern end of Sairee starting at Tarna Resort. The locals will tell you how to get there if it isn’t clear. There is a path pretty much the whole way which will take you past some farmers then into dense jungle but the path will always be visible.
Tanote Bay is also very close so you could kayak from there slightly north to Laem Thian.
Best for: adventure & complete isolation (with caution)
Which of Koh Tao’s Quiet Beaches Will You Choose?
What makes Koh Tao special isn’t just that it has beautiful beaches — it’s that you can still find ones that feel quiet and untouched, even as the island’s popularity has grown.
You can spend one day snorkelling with turtles, the next discovering somewhere more hidden like Haad Sai Daeng, and the next completely switching off at Sai Nuan.
Because the island is so small, it’s easy to explore multiple beaches during your stay, and I’d definitely recommend doing that rather than sticking to just one.
If you’ve got the time, rent a scooter or hop in a taxi and spend a few days beach hopping around the island. That’s when Koh Tao really starts to stand out.
And chances are, your favourite beach will end up being one you didn’t even plan to visit.
