Thailand :: Similans : Elephant Rock

Named after the bulbous looking rock formation to the south of Koh Similan (island number 8), this dive site is one of the best around. Below the surface it offers gigantic stacked boulders and a labyrinth of swimthroughs, arches and caverns. Marine life is abundant and huge schools of yellow goatfish and snappers can be found around the deeper levels

Watch out for thermoclines and currents here. Also keep an eye on the open ocean where you may spot bigger visitors. A lot of the huge rock walls appear quite barren but close inspection can reveal tiny anemone shrimps, crabs and nudibranchs.
