Similan islands scuba diving liveaboard

Liveaboards in Thailand are one of the best ways to explore the Andaman Sea, with the Similan Islands ranking as one of the top ten scuba diving and snorkeling destinations in the world. The Similan and Surin Islands National Park includes the nine islands of the Similan archipelago, as well as the outlying Koh Bon and Koh Tachai Islands, and dive sites around the five islands in the Surin chain. This area offers some of the best diving in Thailand.

​

Each island and dive site caters to all interests and skill levels. The diverse underwater world attracts divers from around the world. New divers can enjoy calm, sandy bays with excellent visibility, while experienced divers and underwater photography enthusiasts will appreciate the variety of topography and abundant macro marine life.

​

Shallow tropical coral reefs, towering pinnacles, and expansive coral gardens provide a breeding ground for numerous fish species and Hawksbill turtles. Wall dives and ridges host passing schools of manta rays, and those seeking shark encounters can spot several species.

​

Richelieu Rock, the highlight of our Similan Islands liveaboard itinerary, is a collection of pinnacles forming a crescent just north of the Surin Islands. Richelieu Rock deserves multiple dives as it's too vast to explore in just one or two. The underwater attractions here are diverse, from tiny macro life to the chance to encounter the largest fish in the sea, the whale shark, which is commonly seen in this area.
