How to Get from Koh Rong to Trat
Contents

Koh Rong's white sand and clear water sit at one end of this trip, Trat, the gateway to Koh Chang and Koh Kood, at the other. In between lies the Thai border, and right now the land border between Cambodia and Thailand is closed. The old overland route through Koh Kong does not work.

Koh Rong to Trat: the border situation

Land borders and crossings between Cambodia and Thailand continue to be suspended, including the crossing at Cham Yeam and Hat Lek, which used to link Koh Kong with Trat. The UK Foreign Office advises against all but essential travel to within 20 km of the land border with Thailand.[1] Until the crossing reopens, travel between Cambodia and Thailand by air and continue to Trat from the Thai side.

Leaving Koh Rong

The first step is the boat to Sihanoukville on the mainland. The crossing takes 45 minutes.[2] Boats leave Koh Rong twice a day.[3] From Sihanoukville, Giant Ibis runs buses to Phnom Penh at 13:30 and 19:00,[4] and Phnom Penh is where most travellers pick up a flight to Thailand.

Book the boat so that you reach Sihanoukville in time for the bus, and keep a buffer if you have a flight the next morning.
