Sihanoukville is one of the best destinations for scuba diving enthusiasts in Southeast Asia. Although its water is not ideally crystal as in Nha Trang Vietnam or Koh Tao Thai Land, Sihanoukville also boasts great species diversity and colorful coral reef. With mushrooming certified dive shops, you will be assured of value for money and hassle free service, especially with Frogman Diving or Scuba Nation.
The most gorgeous places for scuba diving are marine areas around Koh Rong and koh Rong Samloem islands. The best time to do it is in March- May and avoid the Sihanoukville's rainy season (June – November).
