Siem Reap to Koh Rong: Best Routes and Connections

How to travel from Siem Reap to Koh Rong, including road, flight and ferry connections through the coast.

There is no single direct journey

You need to combine inland travel with a ferry from the coast.

Fastest practical route

A flight plus onward transfer can save time when schedules work.

Overland route

Bus or minivan travel is cheaper but turns the move into a long travel day.

Protect the ferry connection

Leave margin between arrival on the coast and your boat departure.

My advice

Treat this as a full relocation day rather than trying to squeeze major sightseeing around it.
