Shark Fin Reef

Similan Islands dive site

Location: 3 km off the east coast of Koh Payan (Similan Island #3)

Depth: 8-35 m

Type: Sloping hard coral reef and boulders.

Level: Suitable for all levels of diver

Description: 

Shark Fin Reef is often the last dive of a Similan liveaboard trip (the other popular last dive is Boulder City,  it’s basically part of the same submerged rocky ridge) because of it’s southerly location in the Similan Islands chain.

At low tide the rocks break the surface of the water to resemble a shark fin. It is also a good site for spotting larger pelagic fish. Bumphead parrotfish, Napolean Wrasse and Leopard sharks are all here and manta rays pass by too.

Shark Fin reef is like two different dive sites and could be dived more than once. On the northeastern side is a sloping reef of hard corals and on the south west the boulders drop off into deeper water. Swim-through’s make natural passage ways from one side to the other.

The northeastern reef has the more prolific marine life. Look out for smaller stuff in the sand rumble between the coral patches. Leaf fish are seen here as are blue ribbon eels. Nudibranchs are numerous and a good divemaster will be able to point many out to you.

How to dive the Similan Islands

You can dive the Similan Islands by day trip from Phuket or Khao Lak, or by liveaboard. Liveaboards are ideal given the size of the area, the variety of dive sites, and the distance from the mainland.

A typical Similan liveaboard itinerary is 4 days 4 nights and also includes Koh Bon, Koh Tachai and Richelieu Rock. Shorter 2d1n or 3d2n trips are also available.

If you don’t mind longish transfers then Similan diving day trips with 2 dives run five days per week from Phuket.

The Similan Islands diving season is from 15 October to 15 May.
