    60 km west of Khao Lak, the Similan Islands are a spectacular chain of nine granite islands.
    Tropical jungle and brilliant white sandy beaches are surrounded by warm, crystal clear water.
    The surrounding Andaman Sea is teeming with colourful marine life and stunning corals.

    Koh Bon & Koh Tachai

    North of the Similan Islands, but part of the same national park, lie Koh Bon and Koh Tachai.
    Have your chance to go diving with Giant Manta Rays at the magnificent Koh Bon,
    Koh Tachai is often a highlight on a Similan Liveaboard with its huge schools of bigger fish.

    Thailand’s best dive site

    Stunning soft corals, huge diversity of marine life and an occasional Whale Shark.

    Richelieu Rock is the furthest North of all the dive sites on the West coast of Thailand.

    So far North in fact, most Similan Islands diving day trip boats cannot get there.

    Don’t worry, Big Blue’s Similan Liveaboard typically does 3 dives there each trip,

    and our Similan Islands diving day trips go to Richelieu Rock 3 times a week!
