It’s fairly easy to get from Sihanoukville to Koh Rong. You can catch either the fast ferry or slow ferry to the islands off the mainland, which run from Sihanoukville multiple times per day. The slow ferry takes around 2 hours, and the fast boat takes around 40 minutes.
Duration: 40 minutes
Times: 8am, 11am, 3pm
Price: The fast boat costs $20 each for a return ticket, or $25 for an open return ticket.
You must book your return journey on the boat 24 hours in advance to when you want to travel back to the mainland, so if you’re only spending 1 day in Koh Rong, you’ll need to book a seat on the return boat when you get to the island. This can be done at Koh Rong Dive Centre, which is located on the pier.
