★★★★★ Richelieu Rock

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.

★★★★☆ 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

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.

★★★★☆ 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.

★★★★☆ 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.

★★★★☆ 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.

★★★★☆ 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.

★★★★☆ Natai Pier/ท่าเรือหาดนาใต้

Natai Pier, located in Phang Nga just north of Phuket, isn’t a traditional “dive site“ in the typical recreational sense with established dive operators visiting daily. It’s primarily a local fishing pier. Local shore dives or snorkeling occur in the vicinity,

★★★★☆ Boonsung (Wreck)

Boonsung is a zinc dredge that has been underwater for about 30 years and broke into several pieces after the Tsunami. It is a very fishy dive site perfect for beginners and advanced divers. It is recommended to bring a dive light to see into all of the crevices.

★★★★☆ Koh Bon, North Reef

Koh Bon North Reef offers a sloping reef with hard corals transitioning to a sandy bottom (10-30m). This relaxed dive is great for beginners and offers good visibility. While mantas frequent the West Ridge, this side provides ample reef fish, including barracudas and moray eels.

★★★★☆ Koh Bon, North Ridge

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.

★★★★☆ Koh Bon, The Bay

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.

★★★★☆ Breakfast Bend

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.

★★★★☆ Whaleback Rock

Whaleback Rock Bay, Similan Islands, offers a more sheltered dive experience than the pinnacle. It features a sloping reef with sand patches and scattered coral bommies. This area provides calmer conditions, making it suitable for a more relaxed dive or when currents are strong elsewhere.
