🇹🇭 Elephant Head Rock (Hin Pousar)

Similan Islands, Phang Nga, Thailand

The signature Similan dive — a chaos of house-sized granite boulders between Islands 7 and 8, stacked into arches, tunnels and canyons you swim through rather than over.

Hin Pousar between Similan 7 and 8: the rocks above water (OpenStreetMap outline) ringed by 5 m shallows, the boulder maze with its swim-throughs, boulder groups at 20–25 m and 25–35 m around it; positions are approximate. The swim-through depths (a wide one from 26 m, one from 20 m up to 16 m) come from IDC Phuket and DiveZone; their exact places in the maze are not known and are marked roughly. Currents can be strong and change direction between the boulders.

Hin Pousar, between Similan Islands 7 and 8. Above water a single rock breaks the surface in a shape that reads, with some goodwill, as a half-submerged elephant. Below it, the site is the best example anywhere of what Similan granite does: enormous rounded boulders piled on each other by nothing more than weathering and gravity, leaving a three-dimensional maze of swim-throughs, tunnels, arches and vertical canyons.

It runs to 50 m at the deepest, though 30 m covers everything worth seeing. Currents can be strong and they change direction between the boulder stacks, which is part of the difficulty and most of the fun.

Dived 25 November 2013 to 30 m — the deepest Thai dive in the log.
