Koh Rong Samloem is reached by boat from the mainland, so the trip from Kep combines a land leg along the coast to Sihanoukville with a boat to the island. Royal Railway's southern line serves both Kep and Sihanoukville,[1] and booking platforms also sell a combined van and ferry ticket.
Kep to Koh Rong Samloem by Train and Boat
The train listed in October 2026 leaves Kep (Prey Thum station) at 10:50 and reaches Sihanoukville at 13:46. Normal class costs $9 and first class $17.[2] The return train in the same listing leaves Sihanoukville at 14:00.[2]
From Sihanoukville you continue by boat. Buva Sea runs speedboats from the mainland to Koh Rong Samloem.[3] Check the boat departures of your travel day before you rely on a train that arrives at 13:46.
Kep to Koh Rong Samloem by Van and Ferry
Booking platforms sell one van and ferry ticket for the whole trip. They list the journey at about 4 hours 15 minutes to 5 hours 15 minutes and at about $24 to $27 (October 2026).[4] With a combined ticket you do not buy the boat separately, but confirm with the seller where on the island the boat lands.
