Koh Russei or Bamboo Island (Khmer: កោះបស្សីKoh Russei ) is one of a group of small islands in the Gulf of Thailand located about 10 km off the coast of Sihanoukville city, in southern Cambodia. For many years, Koh Russei was remarkable only as a small naval outpost. However, increasing development and rising tourist numbers in Sihanoukville brought tourism to the island. At the time of writing (2007), several companies offer bungalows for rent and the island has become a popular holiday destination for both visitors and residents of Cambodia.
