    Beacon Reef

    Beacon Reef is the main reef of Koh Similan parallel to the island’s beach. It features an abrupt drop off with a clashing variety of hard corals from 35 m almost to the surface. This site has most diversity of vigorous hard corals in the Similan Islands, for more that 300 species. The rich marine life includes myriad nudibranches, devil firefish and scorpionfish. The devil fire fish claims one of the most beautiful fish in the sea. One of the puzzling species on this reef is the bigeyefish that gradually cruises the flats of the reef or stay under the coral ledges. The fish has an ability to change color from red to silver, changing its color to fit its mood.

    The currents and the surface conditions are calm and easy, giving divers an overwhelming yet peaceful dive.
