Big Blue Diving Khao Lak

Big Blue Diving has been offering diving in Thailand for over 20 years and in Khao Lak since 2003.
Khao Lak is the perfect departure point for The Similan and Surin Islands. 
The clear waters of the Andaman sea typically provide great visibility, and a huge diversity of marine life.

Our Similan Liveaboard and Similan day trips offer diving at both the Simian and Surin islands including the amazing Koh Bon, Koh Tachai and Richelieu Rock wildly regarded as Thailand’s best dive site.
