Diving Khaolak to Locals wreck

Near Khaolak are several former and modern remains.

  • Boonsong wreck : This wreck rests in 45 minutes of navigation opposite the village of Bangsak.
    The former boat of tin mines, it flowed in 1984 in a depth of 18m.
    Considered too dangerous because too much near the surface, Thai Marine was called to blow up the boat and reduce her height by the collapse of bridges, to establish the wreck which we know today, 10 meters in height and scattered on more than 80 m.
    Over the years, hard and soft corals developed on the hull, which so became an artificial cliff, attracting naturally the big shoals of fish. The wreck of Boonsong establishes the only “reef” in the middle of a huge sandy surface, and a big variety of shellfish and fishes settled in it – sea horses – angelfishes – barracudas …
  • Condreco wreck : This wreck rests on its side, in a 20 meter depth, a few hundred meters away from the beach Thai Muang.
    Also used for the transport of tin, Condreco made wreck in September, 2000.
    In excellent state and covered with soft corals, we find a large number of moray leopard there, and any sorts of ptéroïs – lion fish and scorpion fishes. It is also possible to observe ghost pipe fish.

These two remains are made in dive in the half-day.
