Koh Rong travel guide

Seven kilometres of Long Beach, glowing plankton and jungle trails

In short

Koh Rong is a large, forested island off Sihanoukville with 43 km of beaches, a party village at Koh Touch and the quiet sweep of Long Beach. Come between December and April for dry weather and calm crossings. Stay three or four nights. Prices are low, and Cambodia issues e-Visas and visas on arrival.

Koh Rong lies about 25 km off Sihanoukville in the Gulf of Thailand and is Cambodia's second-largest island. Of its 61 km of coastline, some 43 km is sand, and the interior is mostly forested hills within the Koh Rong Marine National Park.

Getting there

Boats from Sihanoukville

Every visitor arrives by sea from Sihanoukville, since Koh Rong has no airport or bridge. Fly into Sihanouk International, 17 km from the piers, or bus down the expressway from Phnom Penh in about three hours. Fast boats cross several times a day, slow wooden ferries take about two hours, and most land at Koh Touch.

Fast boat
Several daily departures from Sihanoukville, far quicker than the old ferries
Slow ferry
About 2 hours, with wooden benches, an open roof deck and a basic toilet
Sihanouk International (KOS)
Taxi for the 17 km to the Sihanoukville piers
From Phnom Penh
Bus to Sihanoukville in about 2.5 to 3 hours on the expressway
  • Boarding is often across a single plank, so pack light and keep one hand free.
  • Carry water, a hat and sunscreen, because not every boat sells drinks and the roof deck has no shade.
  • Check that your boat company will drop you at your own beach; rival operators do not always carry each other's guests.
  • Some boats continue to Coconut Beach or Sok San; confirm your stop when booking.

Know before you go

What makes Koh Rong worth the trip, and what catches visitors out.

Why travelers love it

  • Long Beach at sunset, seven kilometres of pale sand with the sun dropping straight into the sea.
  • Night swimming on a dark beach, where every kick lights up the plankton.
  • Snorkelling off the shore and on boat trips to the reefs around the island.
  • A jungle walk between beaches on the trails behind Koh Touch.
  • A cheap Khmer dinner in Koh Touch village before the bars start up.

Good to know

  • Bring cash from the mainland, as card payments and ATMs are limited away from Koh Touch.
  • Simple bungalows may run on generators for part of the day and use stream water that can look brown.
  • Crossings get cancelled in rough weather, so leave a spare day before any flight.
  • Carry water and snacks on the boat, since not all of them sell any.

Weather in Koh Rong, month by month

Month-by-month climate figures for Koh Rong are being researched.

Pier night in Koh Touch, sunset below Sok San

Two nights on Koh Rong work well. Take a morning boat from Sihanoukville to Koh Touch, swim by the pier and eat at a Khmer canteen a lane back from the sand, then look for glowing plankton on a dark beach. On day two, cross by road or boat taxi to Long Beach and walk to Sok San village.

On day two, cross to Long Beach on the west coast, by road or by boat taxi, and walk as much of its seven kilometres as you like. Sok San village sits at the northern end, with a small lagoon behind it and, in the wet season, a waterfall about five minutes into the forest. Stay for sunset, which drops straight into the sea on this side of the island.

Give the last morning to the water: a snorkelling trip to the nearby reefs, or a guided walk on the jungle trails between beaches. Leave the afternoon free before the boat back, and keep a spare day before any flight in case a crossing is cancelled.

Koh Touch canteens, evening seafood grills and resort meals

The best-value food on Koh Rong comes from the Khmer canteens in Koh Touch village, a lane or two back from the beach, where rice dishes, noodle soups and fresh-fish stir-fries cost a fraction of resort prices. In the evening, shore places grill fish, squid and prawns. On the far beaches, ask whether your resort includes meals.

Every bungalow resort runs its own restaurant, pricier but calmer. On the far beaches it may be the only kitchen for kilometres, so ask before booking whether meals are included and what hours the kitchen keeps. Simpler places often run on a generator mainly in the evening, which limits cold drinks during the day.

Drinking happens in Koh Touch. Most restaurants serve local beer and cocktails, a few sell buckets, and nearly everything shuts around midnight, leaving one or two bars open late. The all-night parties on Police Beach take place on set nights each week and only get going after midnight, with boats or a short walk back to the village at sunrise.

Choosing between Koh Touch, Long Beach, Sok San and Coconut Beach

Most visitors see three or four of Koh Rong's 23 white-sand beaches. Koh Touch, by the pier, is busy and handy; Police Beach, a short walk west, is loud on party nights; and Long Beach, seven kilometres of pale sand on the west coast, made a 2026 list of the world's top ten beaches.

For real quiet, sleep at the Sok San end of Long Beach or on a bay served directly by boat, such as Coconut Beach. Confirm before booking that your boat stops there, and expect basic power and showers fed by mountain streams, sometimes with a brownish tint.

The east coast is different again. Doeum D'keuw is a fishing village partly built over the water, and Prek Svay further north is the last settlement on that shore. Neither is set up for tourists, which is the appeal: arrive by boat taxi, walk through politely and buy a drink or a meal while you are there.
