Who is it for?
Best for
- Beach resetters — Long Set's 6 km of white sand still feels early
- Plankton chasers: moonless-night swims glow for real
- Hammock-budget travellers before the islands gentrify further
Skip if
- You need reliable AC, ATMs and clinics — infrastructure is 'island basic'
- Wet season (Jun–Sep): ferries thin out, some resorts shut
01Overview
Twenty-eight beaches on an island still mostly forest. Koh Touch does the hostel-bar thing; walk twenty minutes and you're alone with squeaking white sand. At night, plankton light the shallows blue-green wherever you move your hands.
02Don't miss
- Long Set (4K) Beach — seven kilometres, often seven people
- Night swim with bioluminescent plankton (moonless nights best)
- Sister island Koh Rong Samloem's Lazy Beach for total shutdown

11Questions we actually get
Koh Rong or Koh Rong Samloem?
Rong for beaches + some life, Samloem for total switch-off; ferries connect them.
When for plankton?
Any dark night away from lights — schedule around the new moon.
Day trip possible?
Technically, but the ferry timings eat it; two nights is the honest minimum.
