Sihanoukville Scuba Diving


The waters off of Sihanoukville and the nearby islands offer some good scuba diving opportunities.


Coral encrusted rocky reefs surround many of the local islands, supporting abundant hard and soft corals, sponges, anemones and an assortment of fish life including sting rays, moray eels, dolphins and even whales. Experienced divers report that the variety and concentration of marine life along the reefs is impressive.


Good dive sites can be found within a two hour boat trip of town, making for an easy day trip, but the very best sites are 4-6 hours out.

The local waters are warm (consistently between 27-31C) and though visibility can be quite variable, especially during the monsoon season. In the diving season from October to June visibility ranges from 10-25 meters on good days, even at nearby islands such as Koh Rong Samloem - better at more distant sites such as Koh Tang. Most of the dive sites are comparatively shallow (around 15 meters) and gentle currents around the islands allow drift diving over the reefs and outcroppings.

Koh Tang, Koh Prins, Poulou Wai
Some of the best diving in the area lay 4-8 hours southwest, around Koh Tang, Koh Prins and Poulo Wai. The area has rocky reefs, depths of 15-40m and much better visibility than reefs closer to shore, ranging from 10-30m, usually around 15m. Koh Prins has two shipwrecks to the northwest at 30-40m. Koh Tang is a favorite diver’s destination. The island played a major role in the 'Mayaguez Incident' and still shows the scarring of the May 1975 battle between American and Khmer Rouge forces. The surrounding waters offer several reefs and outcroppings displaying a particularly colorful variety of hard and soft corals, an abundance of other marine life, and consistently good visibility.
