Big Blue Diving Khao Lak

Group-postcard

Big Blue Diving has been offering diving in Thailand for nearly 20 years and in Khao Lak since 2003. Khao Lak is the perfect departure point for Similan Islands diving trips. The clear waters of the Andaman sea typically provide much better visibility, and a greater diversity of marine life, than the East coast of Thailand. Our Similan Liveaboard and Similan Islands diving day trips both offer diving at the amazing Richelieu Rock; Thailand’s best dive site.

Where Are We?

Big Blue Diving has offices in Khao Lak and Bang Niang, as well as the Big Blue Diving Resort on Koh Tao. We pride ourselves on high quality service that brings our guests back to dive with us year after year. Our Similan Liveaboard, the MV Hallelujah, offers luxury Thailand diving trips at competitive prices. Similan Islands diving day trips on the Blue Dolphin offer the most convenient opportunity for diving the Similans, Koh Bon, Koh Tachai and Richelieu Rock.

    The Similan Islands

    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.

    Richelieu Rock

    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!

      "Clear, warm waters”
      My husband and I went with Big Blue on a
      day trip to Islands 8 and 9. As a snorkeler
      and a diver we both had a great day.
      The dive masters were professional
      and enthusiastic. Their boat is modern
      and spacious. They were punctual to pick
      us up and friendly throughout the day.
