From turquoise water and barefoot island days on Koh Rong Samloem to the neon sprawl of Bangkok is a classic backpacker run across the Gulf of Thailand. It is a full day and night of travel.
Because Koh Rong Samloem is an island, the journey starts on the water: the ferry to Sihanoukville takes about 45 minutes, with departures from Koh Rong Sanloem at 11:00 and 14:15.[1] Operators bundle the boat, vans and the border bus into one ticket. You can compare and book on GoAsia.cc.

At the border you get off with your luggage, clear Cambodian exit immigration, walk across and enter Thailand on foot.

The Ferry + Minivan + Sleeper + Minivan ticket costs about $66 on booking platforms (October 2026) and also takes about 20 hours.

Tips for Traveling from Koh Rong Samloem to Bangkok
- Visa: Check the Thai entry rules for your nationality before you travel.
- Pack essentials: Keep a daypack with snacks, water, a power bank and a light jacket or sarong, because the air conditioning on sleeper buses and minivans runs cold.
- Island departure: Koh Rong Samloem has several piers, including Saracen Bay and M'Pai Bay. Confirm which pier your boat leaves from.
- At the border: Stay with your group and follow the transport coordinator, who often hands out a sticker or tag so you board the right bus on the Thai side.
- Book ahead: The route involves several transfers and few daily departures, so book a few days ahead in high season.
