Where to go snorkelling in Thailand

by Mihai Pinzariu on September 25, 2019

Thailand offers a range of exceptional beaches and islands to explore while snorkeling, all crawling with huge schools of fish and colourful coral life. The beaches are amongst the best in the world, and while most are popular with tourists, you can still find a few secluded spots to explore the underwater world in solitude.

The waters around Thailand are truly like an aquarium, and you can easily reach most of the best snorkeling sites straight from shore. Whether you’re a beginner or advanced snorkeler, you’ll be able to see the best of Thailand’s sea life along many of its beaches. There are so many places to go it might be a struggle knowing which are the best, so here’s where you should go snorkeling in Thailand.

Fish in Thailand:

  • Batfish, Chevron Barracudas, Blue-Spotted Stingrays, Clownfish, Clown Triggerfish, Emperor Angelfish, Harlequin Sweetlips, Leopard Sharks, Lionfish, Manta Rays, Moorish Idols, Moray Eels, Pink Anemone Fish, Seahorses, Titan Triggerfish, Turtles, Whale Sharks, Yellow Boxfish, and more.

Corals in Thailand:

  • Branching Corals, Crown of Thorns Starfish, Elkhorn Coral, Encrusting Corals, Finger Corals, Fire Corals, Foliose Corals, Indica Nudibranchs, Mushroom Corals, Polka Dot Nudibranchs, Red Anemones, Table Corals, and more.

Best places to snorkel in Maui

Ao Niang Bay

Where: Koh Kradan
Details: This is Thailand’s best snorkeling destination for people who want to explore nature away from the tourist crowd. Koh Kradan is one of the quietest islands in Thailand, full of luscious untouched landscapes, crystal clear secluded beaches, and a spectacular reef to explore. Ao Niang Bay is the best spot for snorkeling, an 800-metre long beach with loads of vibrant marine and coral life to explore right off the shore. This island is part of Hat Chao Mai National Park, so the reefs are healthy and protected.


  • The best place to enter the water is next to the Ao Niang Resort restaurant. Once you enter there’ll be a channel you can swim or walk through to the drop-off. From there you’ll find excellent snorkeling for 200 metres to the right and 800 metres to the left. Enjoy!


  • Bathrooms and small kiosk on-site.

Aow Leuk Beach

Where: Koh Tao
Details: A beautiful white sandy beach with sparkling blue waters, this is one of Koh Tao’s best snorkel spots if only for the view alone. There are coral reefs on either side of the bay with access right off the beach, and you don’t have to go far to feel like you’re in an aquarium. With views of Shark Island in the background, you can snorkel amongst triggerfish, baby sharks, clownfish, and a variety of other marine life.


  • The water here is calm and the reef starts in the shallows, making this the perfect spot for novice snorkelers and children.
  • If you come at the right time of year, you can spot baby blacktip reef sharks swimming in the shallows, with the adults trailing further out about 500 metres from shore.


  • Bathrooms, food & drink, and snorkel hire available on-site.

Koh Larn

Where: Pattaya
Details: This beautiful island has turquoise waters, numerous beaches, and an abundance of coral reefs to explore. Dubbed as ‘Coral Island’, you can bet there that there’s some exceptional snorkeling to be had here. With a huge fish population as well as colourful hard and soft coral life, you’ll be swimming amongst rabbit fish, butterfly fish, angelfish, stingrays, clownfish, and it’s your best bet for spotting a tawny nurse shark or blue spotted ray in this area.


  • You can reach Koh Larn by catching a 1 hour ferry from Pattaya. It’s also a popular destination for snorkeling tours.
  • The best snorkeling beach on Koh Larn is Naul Beach, where you can explore the marine life in shallow waters. Look out for the coral garden full of seahorses!


  • All the beaches on the island will have bathrooms and showers on-site.

Koh Lipe

Where: Tarutao National Marine Park
Details: This island paradise offers some of Thailand’s best snorkeling. With calm, warm waters surrounded by more than 30 islands and hundreds of incredible reefs to discover, this is a prime snorkeling destination with tonnes of sites to explore. The whole area is rich in diverse, colourful marine life, including fish, bioluminescent plankton, turtles, and an abundance of beautiful coral life.


  • You can snorkel straight off the shores of Koh Lipe, or hire a kayak and explore one of the many beautiful surrounding islands, just a 5-10 minute ride away.
  • Some of the best spots to snorkel in Koh Lipe are Sunrise Beach, Sunset Beach, and Pattaya Beach, where you can easily swim to other small surrounding islands in deep waters populated with marine life.

Koh Nang Yuan

Where: Koh Tao
Details: These three islands are connected to Koh Tao by a beautiful white sandbar, and are a must visit when in Thailand. With a shallow, protected coral reef lining the islands you can enjoy snorkeling in crystal clear waters with hard and soft coral, lots of sea life, and some of Thailand’s best waters. Besides the picture perfect setting, you can also feast your eyes (and GoPro) on clownfish, anemones, butterfly fish, clams, parrotfish, and more.


  • This is a popular spot for diving and snorkeling tours (due to its sheer beauty), but it does mean that the corals are damaged in some places.
  • There is an admission fee of 100 bahts for adults (50 baht for children) to enter the snorkel site.
    You’ll also need to take a boat to reach the island or organize a snorkeling excursion. For more detailed information on this snorkel site, click here.

Maya Bay

Where: Ko Phi Phi
Details: If you’ve ever watched the movie The Beach, you’ve wanted to visit this jaw-droppingly beautiful setting. A strip of white sandy beach enclosed by towering green cliffs on three sides, Maya Bay is protected from the open ocean and almost entirely covered in coral reef. You’re surrounded by jungle and crystal clear waters filled with hundreds of colourful fish, but it’s worth noting that a lot of the coral life here has been damaged due to excessive tourism.

  • Information:
    Maya Bay is accessible only by boat. It’s one of Thailand’s most popular tourist destinations so you’ll find plenty of guided snorkeling tours and boat excursions to take you. Most of the snorkeling will happen off your boat, and the tours generally come with meals and refreshments.
  • If you want to avoid the crowds then you can organise for a private boat to take you to the island – try and arrive before 9 and after 5 for the quietest periods. There is also an admission tax of 200 baht per person for landing on the beach.
  • This is one of Thailand’s most beautiful landscapes, but be aware that you’ll be sharing the water with hundreds – if not thousands – of other snorkelers.

What customers are saying about us…

“Awesome set.

Loved the complete set. I even used the waterproof phone pouch to take photos and videos underwater. It made my Fiji experience so much better than using the free snorkel set that hurt your face after 2hours and leaving a sun/mask mark. The ninja leaves no marks and gives great vision under water in comparison. It did take some getting used to but it definitely paid off! Only frustration is that the tightening straps are quite basic; they should be much simpler to loosen and tighten both in and out of water.” – Jock

The Ninja Shark Snorkel mask is awesome!

We bought these snorkel masks as we were going on a tropical holiday which included snorkelling tours and we both hated breathing through traditional plastic snorkels shoved in our mouths. My partner in particular did not want to snorkel because of this. These snorkel masks are FANTASTIC and were GAME CHANGERS. We did several lots of snorkelling on our holiday and every time, we were able to lie in the water, breathe normally and focus on looking underwater without worrying about breathing. Even if you dive underwater with these masks, the valve blocks water from coming into your snorkel mask. I bought the premium Equaliser Pro with the ability to pinch your nose if diving and my partner bought the basic model. Both are fantastic products - comfortable, easy to wear and highly recommended. You need to fit it tightly but it's really comfortable in the water and doesn't leak. Even when you come up you don't need to take it off, just keep breathing normally. I loved snorkelling with this product and even my anti-snorkelling partner really enjoyed it and felt this mask was a game changer.

Bloody love this!

Never snorkelled in my life. Petrified of putting my head under water. But now my neck is bad - if I don't alter the way I swim - then no more swimming for me. This has opened 'a whole new world' - (haha -that songs stuck in your head now) - to me. I'm just using my ninja gear in my gym outdoor pool atm. My legs are getting so strong - and my lungs too - as I'm doing some great breathing. I have huge surgery coming up soon - and i believe this is allowing me to get to a great level of fitness - in preparation. Honestly - i can't go on enough about this product enough. My friend bought a cheaper version. She's given it away already... say no more 🤿🤿🤿

Great design

This is the best snorkel mask I’ve ever had. Very comfortable on face, easy to breathe. I am not a good swimmer, it makes me feel safe and enjoy snorkelling without distraction. Thank you ninjiashark.

Got one of these for me and my 7 year old daughter for Xmas. We’ve used them twice already and love them!! So much easier to breathe, can see so much and just makes the whole snorkelling experience better! Would highly recommend!

Mermaid M. (Townsville, AU)

While travelling in Timor leste l met a fellow snorkeller. We snorkelled for 10 days together the food was shit but the water was stunning. The friend was using Ninja Shark fins and mask mine were steaming up, letting in water and heavy. On arriving back in Australia l ordered straight away.
I was a little bit anxious on receiving my order as the mask was quite different to my old one and the fins were short and adjustable ( l wanted them to be my size ! ) well to my luck the weather was beautiful ( yes mid winter in Mackay ) and perfect for boating so off we scooted to Cockermouth ( don't laugh it's a real place ) jumping in and WOW I'm now a mermaid 🧜‍♀️ the mask and fins felt like part of me. I actually cried as not only was the equipment allowing me to explore as l wanted but the reef was STUNNING. So lm indepted to Ninja Shark for making me the mermaid l always aspired to be 🧜‍♀️

Took it to Tahiti

I wasn’t quite sure about getting a full face mask but bought mine (Electra package) before a trip to Tahiti which we got home from yesterday - absolutely LOVED it!!! I’ll be getting one for my wife before our next trip to a similar destination. BTW I make LOTS of crazy videos with lots of toys.

Super quality & fit

So happy we got Ninja shark, perfect for Great barrier reef snorkel day.

Ninja Shark Kids Mask

We recently brought the Ninja Shark Kids 3-11 Mask + Fins + Bag package for our 7 year old who absolutely loves it! Will be buying three more for the rest of the family. 😊

Even better than expected!

I saw the kids full face snorkel masks online, and thought they looked pretty cool. I ordered two for Christmas, for my 3 and 6 year olds. Wow, did they have a great time with them!

I wasn't sure how the 3 year old would go with it, but he was comfortable in it almost immediately, and spent hours swimming around and seeing a whole new world of underwater scenery.

They were easy to fit, zero issues with them staying on. No leaks or fog.

They can't wait to get back to the water!

Highly recommend this product :)
