Big Blue Diving Khao Lak

★★★★★ Richelieu Rock

★★★★☆ Koh Bon Pinnacle

Not for beginners! Koh Bon Pinnacle starts at 22m and ends at 45m or deeper. Beautiful vegetation with lots of yellow soft corals are here. There are no descent ropes available. Doing a negative entry is an advantage!

★★★★☆ Koh Bon, West Ridge

★★★★☆ Elephant Head Rock

Located in the middle of the sea between islands 7 and 8 in the Similan Islands, this reef dive site stands out in the middle of the sea. It was named after the shape of the rock sticking out of the water, which resembles the head of an elephant. The point is made up of huge layers of granite, dotted with numerous channels and swim-throughs that create a mystical landscape. The tide is good, and you can expect the feeding scene of the crabs, sharks and big fish in the early morning. In the shallow water, you can often find oversized trevally targeting small fish. This is one of the most dynamic dive sites in the Similan Islands.

★★★★☆ 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.

★★★★☆ North Point

As the name suggests, North Point is the northernmost dive site in the Similan Islands, located on the north side of Island 9. The terrain is varied, with massive granite overlaps forming large walls, channels, and swim-throughs.

★★★★☆ Koh Tachai Pinnacle/The Dome

The Dome is a hidden reef point located about 500m south of Tachai Island. A large dome-shaped bedrock shaped like an upturned plate is dotted around a large granite boulder. The top of is at 12 meters and the current can be the strongest in the area depending on the conditions. As a result, there are many large predatory fish such as blue and white trevally, bluefin tuna, barracudas, manta rays, and whale bays.

★★★★☆ 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.
