About this itinerary

The Similan & Surin Islands are widely regarded as one of Thailand’s premier liveaboard diving regions. Named after the Malay word sembilan, meaning “nine”, the Similan Islands form a chain of granite islands within a protected marine national park that also includes Koh Bon and Koh Tachai. Further north, the remote Surin Islands and Richelieu Rock add healthy reefs and rich marine life to the itinerary. Above water, verdant landscapes, dramatic granite boulders, and white sandy beaches create a striking setting, while below the surface, clear waters reveal vibrant coral reefs, schooling fish, and pelagic encounters that place the Similan and Surin Islands among the top dive destinations in Thailand and Southeast Asia
