Travel time from Koh Rong to Phnom Penh

Hi there, I’d love to hear about your experiences getting back from Koh Rong to Phnom Penh. I saw that by plane it takes 3h30 with a layover in Siem Reap, so no thanks—I was thinking of taking the bus. How much time should I allow between leaving Koh Rong Island by ferry and then the bus, so I can plan my return to France? Or is a taxi an option? Thanks for your tips!

The ferry from Koh Rong to Sihanoukville takes about 1 hour by speedboat, and then Sihanoukville to Phnom Penh is at least 3 hours by bus.

Plan for at least 5 to 6 hours for this trip, including possible delays.

Thanks for your reply! Have a great day
