Why go
Koh Rong Samloem is smaller, calmer and greener than its big neighbour. Most visitors arrive at Saracen Bay, a crescent of soft white sand about three kilometres long on the east coast, where the water is so clear and shallow that you can see your feet when you are up to your shoulders. Low bungalow resorts are tucked behind the trees, and in the evening the bay goes almost silent.
On the other side of the island, Lazy Beach and Sunset Beach face west across the open gulf. They are quiet and a little remote, reached by forest trails or boat, and they live up to their names. In the north, M’Pai Bay is a real fishing village with wooden houses, children playing in the shallows and a few guesthouses.
It is the island for doing very little: swimming, snorkelling, walking forest paths between beaches, reading in a hammock and watching the sky change colour.
The story
Until the early 2000s Koh Rong Samloem was mostly forest, with a few fishing families and a lighthouse. Its name is usually spelled several ways, Samloem, Sanloem or Saloem, a sign of how recently it entered travellers’ maps. Small resorts opened one by one in Saracen Bay, most of them built from wood and thatch, and electricity long came from generators that switched off at night.
The island is part of a wider marine area where conservation groups have worked with local communities to protect seagrass beds and coral reefs. Seagrass meadows here shelter seahorses, juvenile fish and, more rarely, turtles, and in 2016 the waters around the Koh Rong archipelago were declared Cambodia’s first large marine fisheries management area.
M’Pai Bay village shows another side of island life. Families here have fished these waters for generations, and squid boats with strings of lamps head out in the evening. Some households now run guesthouses or cafés, but the rhythm is still set by the sea.
As on Koh Rong, bioluminescent plankton lights up the water on dark nights, and the quiet of Saracen Bay makes it one of the best places to see it.

Getting there
Speed ferries from Sihanoukville stop at Saracen Bay, often on the same runs as the Koh Rong boats; some also call at M’Pai Bay. The crossing takes roughly 30–60 minutes. Many resorts send a boat or a staff member to meet the ferry; tell them your arrival time. Check current timetables and book ahead in high season.
On the island there are no real roads. You walk on trails through the forest or take a water taxi between bays.
