koh rong
Jungle island with long white beaches and glowing plankton at night.
- Best time
- November to April is dry, with calm seas. The rainy season, from about May to October, brings rougher crossings and fewer people.
- How long
- 2–3 days
- Getting there
- Fly KL to Phnom Penh (about 2 hours), then about 3 hours by road on the expressway to Sihanoukville. From there, speedboats reach Koh Rong in about an hour. Sihanoukville also has its own airport.

Cambodia's second-largest island, about 25 km off Sihanoukville, inside a marine national park. Much of it is still jungle and most of the coast is beach, from the bars and guesthouses of Koh Touch to the long, empty sweep of Long Beach. At night, the plankton in the water glows as you swim.
Things to do
- Long BeachSeveral kilometres of white sand on the west coast, often close to empty.Map ↗
- Koh TouchThe main village by the pier, with guesthouses, bars and places to eat.Map ↗
- Glowing planktonWade into the sea after dark, away from the lights, and the water sparkles as you move.Map ↗
- Jungle trailsPaths link some of the beaches through the forest. Go with a guide or a good offline map.Map ↗
- Snorkelling tripsDay boats head out to reefs and quieter bays around the island.Map ↗
Good to know
- Bring enough cash. ATMs are limited, and power can be patchy at smaller places.
- The plankton shows best on dark, moonless nights.
- Boat schedules change with the weather, so don't plan a tight connection back to the airport.
Last checked October 2026. Things change, so check opening times, fees and transport before you go.
