Koh Rong suits a beach trip built on pale sand, warm shallow water and a pace set by the ferry timetable.

We may earn a commission. It never decides our picks.

Koh Rong is an island off Cambodia's southern coast in the Gulf of Thailand, part of Preah Sihanouk province. Go for pale sand, clear shallow water and forested hills that run down to the shore. Most visitors reach it by ferry from Sihanoukville, the mainland port city. Development is concentrated in a few beach areas, and much of the island stays wooded.

The island suits a slow beach trip built around swimming, snorkeling and long meals by the water. Accommodation ranges from simple bungalows to larger resorts, so budget and comfort vary widely. The dry season, roughly November to April, is the usual choice for beach weather. From May to October, heavy showers and rougher seas can disrupt ferry sailings. Koh Rong Samloem, a smaller island nearby, suits a quieter stay.

    Koh Rong FAQ

    How do you get to Koh Rong?

    Take a ferry from the mainland port at Sihanoukville. Sailings depend on sea conditions, so confirm the boat the day before and allow time for the return.

    How many days do you need on Koh Rong?

    Two or more nights gives time for the ferry crossing and a few beach days. A day trip from Sihanoukville leaves only a few hours on the island.

    When is the best time to visit Koh Rong?

    November to April, in the dry season, is the usual choice. May to October brings heavy rain and rougher seas on the crossing.

    Koh Rong or Koh Rong Samloem?

    Koh Rong is larger, with more services and a bigger village. Samloem is smaller and quieter, so choose it for a slow stay.

    Can you visit Koh Rong on a day trip from Sihanoukville?

    It is possible, but the ferry crossing takes a while each way, so a day trip gives only a few hours on the island.

    Do you need cash on Koh Rong?

    Yes. ATMs on the island are few and card payment is limited, so bring enough US dollars or riel for the whole stay.
