Three Trees

This point is located northeast of the 9th island in the Similan Islands. It is named after the three large trees that are used to mark the entry, from a shallow depth of about 5 meters to a reef slope of about 18 meters, beyond which there is a pure white sandy area dotted with isolated roots. Offshore, there are beautiful rocky areas with schools of soft corals, where you can see large fish. Because the tide splits on the island, the tide is clear and you can enjoy drift dives when the tide is strong.

Christmas Point

Christmas Point is located on the western corner of Island 9 in the Similan Islands. It is named after the root of the thornbeam (English name: Christmas tree worm) that grows in clusters. Intricate rock formations eroded by tidal currents create channels and swim-throughs that provide dynamic terrain. Be careful out in the deep area along the rocks, as the tide is fast in some conditions.
