Bon Island, about 50 km west of Khao Lak, is an uplifted limestone island about 20 km north of the Similan Islands. This is a long and narrow ridge point on the west side of the island.

Nice shallow area for diving with a slightly sloping reef. You can swim from the North Ridge over the West Ridge and into the bay. Currents are usually weak to moderate.

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!

Breakfast Bend is a very elongated reef. It is slightly sloping with a max depth of 35m. The upper part is full of hard corals, then from 16/18m there is more sand with isolated coral blocks that are beautifully covered in glassfish.

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.

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.

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.

An easy dive site on Island 8. You can dive in or out of the bay through a channel. You can only dive with little current, otherwise, you can only dive one way as a drift dive. In the shallow area it is very rocky then gets sandy in the deeper depths.

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.
