Christmas Point

Christmas Point on Similan Island No. 9 features a dramatic underwater landscape of massive granite boulders forming pinnacles, arches, swim-throughs and a complex labyrinth of channels. It is one of the Similans' most popular, iconic dive sites, with scattered staghorn and pore coral gardens, colorful soft corals and giant gorgonians on the rock walls. Marine life highlights include schooling fish, large pelagics that follow the currents, and resting reef sharks in the deeper sand channels. This is a boat-only, open-water drift dive with descents typically from a line to about 20-25 m and a one-direction route around the point. The reef drops steeply to 30-40 m and parts extend beyond 30 m, with sand channels descending to about 60 m; swim-throughs and a notable archway occur around 24 m and tunnels are common at 18-25 m. Visibility is generally good, often 20-30 m or more, and water temperatures run about 27-29 °C. Strong tidal currents, usually flowing southwest-northeast or vice versa, are common, so divers should have good buoyancy control, plan descent and drift, and perform a safety stop after ascent.
