Whether you are a professional diver or an amateur snorkeler, these waters are some of the finest in the world.

Koh Nang Yuan, Thailand

You are in Thailand and you love to snorkel.  Koh Nang Yuan is the place for you.  From Bangkok, fly to Champion. 

Board a high speed catamaran to three little teardrops of land connected by a massive sandbar known as Nanyuan. 

The traditional long tail boat is a cheaper way to get to your destination, and is only a 15 minute adventure to Nang.  

You will immediately want to take pictures of the sand and sea, and send them home. Your friends and family won’t believe the beauty of this paradise. 

The topography is exquisite, including the mountains, white sparkling beaches, and warm waters that invite you to view the colourful fish and corals.

only 200 Baht roundtrip

Since you traveled practically around the world to get here, you might as well stay at the Nanyuan Resort, which is the only one on the island. 

Most of the visitors will be Asian, and it is a little costly. But, you are worth it!  

Most of the locals arrive at mid morning, and stay well into the afternoon, because it is so inviting and perfect for couples and families. 

You, however, will be staying for a longer time, so you have the option of experiencing this paradise early and late. 

Here is a video of snorkelling in Koh Nang Yuan’s waters to show you how beautiful they are.

The island is privately owned, and completely eco friendly. For example, no plastic allowed. 

The beach of Koh Nang Yuan is the main attraction, and what is under the water is even better.

Most people say that Koh Nang Yuan is one of the best snorkelling locations in all of Thailand’s waters. 

The soft and hard coral reefs surround the island, and schools of parrotfish and angelfish are there to greet you.


The island has the perfect elevation to provide great lagoon shelter to keep things calm for snorkelling, and the water is crystal clear as well. 

The banana-shaped long boats will take you to some off island snorkelling if you wish. 

Twin Peak and Japanese Gardens are great shallow locations to try. Bring your own gear, or the resort has just what you need, if you prefer to travel light.

Here is yet another video showing snorkelling in Koh Nang Yuang, in Thailand.

Remember that this is an eco island paradise, and touching the coral is not acceptable. 

Yes, they have hiking to the highest peak for great 360 views, and zip lining over the turquoise sea. But you are here to snorkel.

Hotels and Accommodation in Koh Nang Yuan

Currently there is only one resort on the island, Koh Nang Yuan Island Dive Resort.

This resort restaurant is also the only place where you can buy food.  It is worth mentioning that the food there is pricier than in an average Thai restaurant.

All bungalows in the resort come equipped with a refrigerator and some of bungalows with video,or living room.

Of course, you can also stay in the nearby island of Ko Tao. Some of the best places to stay in this island are Dusit Buncha resort, The Place, and Koh Tao Cabana.

On to the next spot…

Koh Rong, Cambodia

How to get there?


Koh Rong is the second largest island of Cambodia.  The island is located in the province of Koh Kong. 

That should be easy to remember. It is in the Gulf of Thailand, about 25 km off the Sihanoukville’s coast. 

There are 43 kilometres of pristine “drop dead” gorgeous beaches. The dense tropical forests cover most of the 78 square kilometres interior.   

Hotels and Accommodation in Koh Rong

Koh Rong is not famous for its pristine white sandy beaches, warm crystal clear ocean waters, and a hot tropical climate, but also for its great accommodation.

Amazing ocean views, private pools, and great food are just some of the things you can find in Koh Rong’s hotels.

Some of the best places where you can stay in Koh Rong are Sweet Dreams Koh Rong, Palm Beach Bungalow resort, Soksan Beach resort, and The Royal Sands hotel.

You can’t go “Rong”?

The world is discovering very quickly how beautiful Koh Rong is, but there is still time for you to enjoy the snorkelling in a very peaceful, uncrowded setting. 

There are 7 bays to explore, weather permitting. This is a picture postcard place for some who want to share this gem with few people, and little development. 

On the other hand, it can be a party destination extraordinaire, so there are others who would say, “the more the merrier.”  

Should it be developed or kept a secret? That is the question. 

From bed bugs to palaces?

There are places to stay, if you’re not too fussy.  You can live in the villages with the locals, or rent something more commercial, if you like such a “Song Saa”.

If you’re going there to snorkel, you have come to the right place. It is only a 45 minute speed boat ride from mainland Sihanoukville.

There are lots of snorkelling tours to sign up with, but it isn’t really necessary. You can snorkel at the best locations without much help at all. 

Here are some suggestions for wonderful snorkelling experiences

The Dive Shop … Snorkel close to the Dive Shop. They will rent you the equipment. Just jump in the water right there. Seahorses, Diamond fish, and Needlefish are waiting to impress you.

Monkey Island South … Just south of Monkey Island, near the village pier, is a superb snorkeling spot. Yellow boxfish, Rabbitfish, Blue Spotted Ribbontail rays, goatfish, and if you’re lucky, groupers. They all live at this location.

Long Beach West … This is a real gem of a find for the persistent snorkeller. 

This next video shows some exquisite Cambodian snorkelling…wow!

If you want to take advantage of Koh Rong’s perfect beaches, diving, snorkelling, and phosphorescent night swimming, go now, or forever hold your peace.

Moving on…

Phu Quoc, Vietnam … Bai Sao Beach

Phu Quoc is Vietnam’s largest island. 

It has a beach called Bai Sao, and many say, that it is the best snorkelling beach in all of Asia. 

The sand is soft, white powder, and the waters are perfect for underwater swimming.  Head to the north part of the beach where a snorkeler’s paradise lies just a few steps into the water.  Look out for the rocks in the water. 

The water is shallow and very calm, so it is perfect for people of all ages and swimming abilities. Most snorkelling destinations have to be experienced by boat, but not at Bai Sao…. and by the way, it’s free!

Check out this video …

Here are a few specific directions on how to get to this secret gem of a beach, that is very under-developed …

From Ham Ninh Village, travel north on the road for 7 km towards Bai Thom Village and the Da Chong Pier.  Bad Sao isn’t far from here. 

Snorkelling at its best!

Hotels and Accommodation in Phu Quoc

What makes Phu Quoc such a great tourist destination is the fact that it offers not only crystal clear waters, beautiful beaches, and great snorkeling spots but also a range of activities, attractions, and accommodation.

Some of the best places to stay in Phu Quoc are Fusion Resort, VinOasis, Sol Beach House, and Green Bay Phu Quoc resort and spa.
