Considered one of the more challenging dive sites with occasionally strong currents, this is one of two spectacular places in the world where you can dive hazard free with bull sharks! Depth is up to about 36 meters and is laden with the most impressive array of sea life from giant groupers to black corals, huge anemone gardens to yellow box fishes. The four fascinating submerged pinnacles will present big pelagic fishes such as barracuda, mackerel and trevallies. Adult and juvenile bat fishes will escort you around the pinnacles. The abundant microscopic food amongst the corals attract schools of fish with possible sightings of whale sharks.


15 km north of Koh Phangan, a block emerges from the sea, and ranges down to 40 meters. The main attraction of this dive site is a naturally formed 15-metre high underwater dive wall or chimney. Divers can ascend from 18 meters up the chimney wall to the surface, making this a unique diving experience. Visibility is usually excellent at around 30 meters. The structure itself is pocked with small holes, which are ideal homes for white-eyed and yellow margin moray eels, as well as large sea anemones. Sightings of reef sharks and manta rays are also common, as are large schools of tuna, jacks, trevallies and barracudas. Even here, whale sharks can be seen occasionally.


The Southwest Pinnacle consists of three rock formations, which range from 4 – 30 meters below the surface, representing a series of short wall dives. At the top of the pinnacles are blankets of underwater plant life in a stunning array of rainbow colors. Between the rocks are many bushy black coral sea whips and gorgonian sea fans. Leopard sharks are often encountered and it is even possible to meet the occasional whale shark. Giant groupers are common here, as are scribbled file fish, masked porcupine fish, yellowtail, barracuda and snapper.
