Khao Lak, Thailand
Our Similan Liveaboard itinerary is carefully designed to showcase the very best of the Similan and Surin National Parks, with our extended five-day expeditions offering an unparalleled diving experience across Thailand’s most pristine marine reserves. With 18 incredible dives over five days and five nights, you’ll have time to truly explore the diversity of these legendary dive sites. Our extended itinerary means we can venture beyond the usual highlights to discover hidden gems and lesser-visited sites that most operators simply don’t have time to reach.
We dedicate our first two full days to the Similan Islands themselves, starting with the spectacular southern sites including the rarely visited Boulder City and dramatic Shark Fin Reef. Day two focuses on the northern Similan classics – the sites that made these islands world-famous amongst divers. After thoroughly exploring the Similans, we head north to the renowned Koh Bon for encounters with manta rays and reef sharks, before continuing to Koh Tachai’s pristine hard coral gardens and diverse marine life.
We spend day four in the Surin National Park, culminating with multiple dives at the world-famous Richelieu Rock – consistently rated amongst the world’s top dive sites for its incredible biodiversity and macro life. Our final morning at Koh Bon offers last chances for those magical manta ray encounters before we cruise back to Khao Lak, giving you maximum underwater time right until the end.
This extended format allows us to dive at a relaxed pace, spend quality time at each location, and explore sites that shorter trips simply can’t accommodate – making it the ultimate Andaman Sea diving experience.
