Koh Tao in Brief
The tiny gem of Koh Tao or Turtle Island is just 21 square kilometers, yet it is the beating heart of diving in the Gulf of Thailand and home to an incredible 20 diving schools and more than 100 professional instructors. Koh Tao's proximity to "under- water classrooms" makes it ideal for beginners. There are dive sites just one kilometer from the island where you can see pelagics, large schools of great barracudas, big-eyed jacks, tuna and giant travellys. There are also clown fish, shark whales and swordfish.

Koh Tao's is also a departure point for trips to the Mu Koh Ang Thong National Marine Park, and its coral makes it great for snorkeling as well as diving. Many international diving agencies are represented on this small island, including PADI, SSI, IANTD, BSAC & NAUI. All course levels are available from beginner to professional, including special courses like UW- photography and technical diving (nitrox) for the more adventurous, so if you just fancy a few days of fun diving or wish to go on with your underwater career, it's all here.

Actually Koh Tao has become the leading area in Thailand for Instructor Development Centers (IDC). IDC's are held at the larger dive resorts or shops with courses running every two months .Equipment quality has also improved with shops using the latest models including Scubapro, Suunto, US Divers, Technisub and Seac Sub. There are repair shops for divers traveling with their own equipment and who may need a service. There is also a selection of retail centers for those who wish to purchase some scuba gear. Safety has been much increased with the nearest decompression chamber located in Samui only 90 minutes away by speedboat and a heliport is now operational on the south side of the island.
