The warm clear waters of The Gulf of Thailand and its abundant marine life gives you an ideal opportunity to take the plunge and explore the underwater world that surrounds these islands.  Whether you are a certified diver or a complete novice, there is a range of dive tours and courses, which encompass all the major dive site destinations around Koh Samui - Koh Tao, the Angthong Marine Park and the famous Sail Rock are all on the itinerary.

Large schools of tropical fish, reef sharks and the awe-inspiring whale shark, combined with good visibility will delight underwater photographers and marine naturalists. The most famous dive site Koh Tao, also known as turtle island, is a haven for divers all over the world, it is located only 27Km North of Koh Phangan, and is easily reached from Koh Samui. All diving companies in Samui are fully PADI certified.

Diving Around Samui and Tao

On Koh Samui and Koh Tao you will find some of the best diving sites in the Southeast Asia region. The largest concentration of diving operators are found at; Sairee Beach (Koh Tao), Bophut Beach and Chaweng Beach (Koh Samui). You can also go on a daily dive trip to Angthong National Marine Park and popular Sail Rock. Whale sharks can be spotted here. The water is rich in colorful corals and has an impressive fish life. There are also a few operators and schools found at Koh Phangan.

Try to find a school with experienced instructors. You will find most of these on the PADI websites.

If you are a beginner or advanced doesn't matter. If you are diligent and have plenty of time, you can study intensively and receive one of these diving qualifications: Scuba Diver, Adventure Diver, Advanced Diver, Divemaster, or Rescue Diver.

If you don't have that much time, join a short-term course to get the basics. You can rent all equipment you'll need, or buy some of it at the school or in scuba diving shops.

The climate is good for scuba diving, but it might be a little windy in October, November and December so the visibility is not always good then.


Snorkeling here can be excellent when the visibility is good. You will find all the equipment at the diving schools, or (if you looking for something basic) in a super market. We would definitely recommend you to pay a few baht extra for better quality and safer equipment. A mask made of silicon is often a little more expensive than one made of rubber or plastic, but it will normally last much longer.

Book your snorkeling trip in any diving school or at one of the travel agencies found on the islands. We recommend you to try a snorkeling trip to Angthong National Marine Park or a weekend (or more) on the beautiful island of Koh Tao.
