Koh Rong is a stunning and virtually undeveloped island about 25 km off the Cambodian coast, close to the beach resort town of Sihanoukville. It is best known for its beautiful beaches, which make up about 43 km of the 61 km coastline, with about 23 distinct beaches of varying lengths. While the sand on most is pristine white, a few have other tints, including a light rose. Famously, the beaches glow on moonless nights thanks to bioluminescent plankton, which are only visible in places with such low light pollution.
Koh Rong has four neighbouring islands, most of which are tiny and uninhabited, but the 9.5-km-long Koh Rong Sanloem has many fantastic beaches of its own, as well as a couple of local villages and a choice of great resorts. If you are planning on staying on either of these outstanding islands, the following information will be extremely useful.
