Similan Dive Sites

Koh Bon

Although the granite inlet is isolated to the northwest of the Similan islands, Koh Bon is still considered to be part of the Similan National Park and south of Richelieu Rock. One favorite dive spot is the western ridge of the island, which falls steeply to the deep sea.

Koh Bon is still considered to be part of the Similan National Park and south of Richelieu Rock. A tin dredger called Boonsung sank around 20 years ago. It is located to the west of Bangsak pier, about 7 nautical miles offshore or about 13 nautical miles away from Tap-Lamu pier. It is a favorite destination for day trips that depart from Khao Lak. The wreck lies on serene flat sand at 18 to 20 metres. The wreck is around 10 metres wide and 30 metres long. The average roof level of the wreck is at 13 to 16 metres long. After the tsunami, the wreck has been broken in 5 to 6 parts. All are fully covered with barnacles and sponges, and only a few corals can be seen here. Sometimes you can see the remains of a fish cage near the wreck. There is a small buoy which the day-trip boats use to moor.Although the granite inlet is isolated to the northwest of the Similan islands.

Marine Life

This site is a cleaning station for manta rays, so there is a high chance of finding at least one during a dive, particularly at the western ridge and northeastern outer reef. Koh Bon also has many kinds of sharks and white-tip and black-tip reef sharks. Sometimes grey reef sharks swim by, and nurse sharks can be seen lying under coral heads.

Schools of yellowtail barracuda, fusiliers, trevellies, sweetlips and black and white snappers are all common in the area, as well as octopuses, sea snakes, and nudibranchs. Manta rays have a distinct circling behavior when feeding on plankton. You can experience and see this for yourself unless you chase them or swim too close, which may make them panic and swim away. Chasing them also wastes your air supply and reduces the chances for other divers to encounter these spectacular creatures.

Dive Tip

Because Koh Bon Pinnacle is a deep site with the top at 18 meters, you should be cautious about no decompression time.Divers can swim back to the reef of the main island if the current is not too strong (by setting your compass to the southeast). Be aware that it would take about 10 to 15 minutes to swim in blue water. On the other hand, it is difficult to swim from the reef to the pinnacle because the pinnacle is quite small. The pinnacle is suitable for experienced divers only.
