There are more than a dozen islands off the coast of Sihanoukville for tourists to hop around. Most of them are yet to be developed for an overnight stay with the exception of Sihanoukville Islands such as Bamboo Island or Koh Russei in Khmer. Many guesthouses, restaurants, and cafes on Ochheuteal and Serendipity beaches offer trips and packages to these islands. To travel to these islands, you can depart from Sihanoukville by boat or from Kep Beach.
These are Sihanoukville Islands
Koh Russei (Russie Island)- Also known as Koh Russey or Bamboo Island is a green, gilt-edged crescent, resting on emerald or blue water. This is the island one always longed for, the archetype from your wildest dreams. Koh Russei is really a jewel of a beach with fine pink or ochre sand and a deep and mysterious forest. For those loving the sun falling into the sea whilst surrounded by jungle sounds, Koh Russei is the place.
Koh Rong (Rong Island)- It is situated west of the Sihanoukville coast. It offers the fantastic strand of beach on its southwest, stretching about 5 kilometers (3 mi). It has fresh water resources on the island and a bustling fishing community on the southeast with basic supplies including fresh water, fish, and crab.
Koh Rong Samlon (Rong Samlon Island) – It is a bit smaller than Koh Rong and situated on its south. Beautiful beaches are on the east coast, where a large heart-shaped bay with some shellfish cultivation is located and on the north shoreline facing Koh Rong. The marine life around Koh Rong Samloem is very diverse and offers some amazing diving.
Koh Tang – It is located quite far from the main shoreline of Sihanoukville. Going there requires trippers to stay overnight on board. It offers interesting diving spots most of which are not frequently explored. The island is home to a military outpost and travelers should expect to be boarded by military personnel when out on the island.
