One of Thailands Best Dive FacilitiesOur Koh Tao Dive School

One of the best Dive Centers in Thailand

As one of the more well-established Koh Tao dive centers in Thailand with dive centers on Koh Tao and in Khao Lak, Big Blue Diving has gained an excellent reputation over our 30 years of operation. Reputedly one of the ‘bigger’ Koh Tao Dive centers’, because we have 3 dive boats compared to most dive shops on Koh Tao who have one, (or worse shared boat space). Big Blue Diving is also the main base of operation for Big Blue Pro, an SSI Platinum Instructor Training Center; Big Blue Tech, the largest TDI training center in Asia, and Big Blue Conservation, our award winning Marine Conservation department led by our own in house Marine Biologists. We also come highly recommended at Big Blue Diving Khao Lak as we enter our 20th year operating luxury 4D/4N Liveaboard trips to the Similan & Surin Islands on board MV Blue Dolphin.
