Richelieu Rock is one of the most popular dive sites in Surin Islands National Park. It is a limestone reef that rises almost vertically from a depth of 35 meters, and appears only at low tide, about 1 meter above the surface.
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.
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.
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.
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!
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.
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 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.
Huge, bizarre boulders underwater that make it look like a city. You can easily find stream shadows if you want to. It leads a mouring-line down to 18m.
Totally shallow dive site if you stay on the island. Afterwards it is a steep sloping reef down to 30m depth. There can be a current. The shallow area is good for snorkeling, training courses, and night dives.
A soothing dive site on the east side of islands 5 and 6 in the Similan Islands. This site is a rolling reef slope along the edge of the island from a shallow depth of 5-6m to around 25m.
This is a reef dive at the southern tip of Similan Island 5. There may be some current, making this a drift dive. This dive goes between rocks and also come to a small overhang.
Princess Bay is an easy bay dive. The reef edge is very beautiful. This site is good for beginners, courses, and snorkelers. This is a slightly sloping reef with a max depth of approx. 20m.
A topographic dive site on the west side of Island 7 in the Similan Islands. It is centered around three huge rocks that are the highlight of the dive with coral slopes on either side. Soft corals, such as sea fans and sea hawks, are growing in the wall and in the deep area off the rocky coast. These areas are home to hard corals such as Hanaya rhinoceros and a wide variety of other creatures.
Located at the north end of the 7th island in the Similan Islands, this dive site is along the northern apex of an elongated island from north to south. Visibility is clear and the granite boulders, eroded by the tidal currents, form several steps from the bottom.
