In the future, you'll be flying right to Koh Rong Samloem International Airport. (or Koh Rong Airport)  But not quite yet.

Fast boats and slow boats go out to the island most days.  On occasion, you'll have to wait a day or two to go out to the island, (or come back).  This is mostly in the months between July and November.

All the bungalows on Koh Rong Samloem Island have their own preferred boat trips.  Usually $15 for a round trip.

Also, private boats can take you out, and the Sun Tours boat sometimes goes to the island for a $30 a day party trip.
