Lak Siam (Koh Rok)
Lak Siam is described as a long sloping reef covering almost the whole east coast of Koh Rok Noi and is called one of the best sites at the Koh Rok islands. The shallows hold large fire-coral gardens, and further down the slope there are bubble corals, giant barrel sponges and big gorgonian sea fans.
