How to Get from Sihanoukville to Koh Rong Samloem

Leaving the mainland behind for the quiet shores of Koh Rong Samloem feels like stepping into a slower version of Cambodia. While Sihanoukville is a busy port city, the island is a quiet retreat of white sand and turquoise water. This journey is the final hurdle between the urban noise and a hammock under a palm tree.

The crossing over the Gulf of Thailand is short, but the departure pier depends on your operator, so check your booking confirmation before you head to the port. The sea can be glassy and calm or surprisingly choppy depending on the afternoon winds, so choosing the right vessel for your comfort level is key to starting your island retreat on the right note.

Sihanoukville to Koh Rong Samloem by Ferry

Taking a boat is the only way to reach the island. Booking platforms list speedboats, high speed ferries, and standard ferries at about $13 one way, with crossing times from 40 minutes to 1 hour 30 minutes (October 2026).^[1] Operators include Buva Sea, which runs speedboats from the mainland to Koh Rong Samloem.^[2] The duration depends on the boat type and the number of stops it makes at various piers around the island.

Speedboat and High Speed Ferry Options

Speedboats and high speed ferries are the most popular choices for those eager to sink their toes into the sand quickly, and they are generally the faster boats. They can feel bouncy when hitting the waves at high speeds. If you are prone to seasickness, sitting toward the back of the boat usually provides a smoother ride.

You can compare schedules and book your tickets on GoAsia.cc to have a seat reserved. Booking ahead matters most in the peak season, which Island Speed Ferry puts between December and February within a dry season that runs from November to May.^[3]

Standard Ferry Experience

The standard ferry is the slowest option and the more relaxed one, taking up to about 1 hour 30 minutes to reach the island.^[1] These are often larger vessels that offer more stability on the water. This is a good choice if you are not in a rush and prefer a steadier pace across the sea.

Tips for Traveling from Sihanoukville to Koh Rong Samloem

• Check your arrival pier: Koh Rong Samloem has several landing points, and moving between bays can mean another boat trip. Ensure your boat operator stops at the pier closest to your accommodation.
• Prepare for wet landings: Depending on the tide and the specific pier, you might have to step into shallow water or navigate a narrow wooden jetty. Wear flip-flops and protect your luggage against sea spray.
• Cash is king: There are no ATMs on neighboring Koh Rong,^[3] and you should not count on one on Koh Rong Samloem either. Withdraw enough Cambodian riel or US dollars in Sihanoukville to cover meals, drinks, and activities.
• Mind the weather: The UK Foreign Office notes that tourist boats sometimes operate despite weather warnings, particularly between Sihanoukville and the nearby islands.^[4] If conditions look rough, consider waiting for a later crossing.
• Sun protection: Even on a short boat ride, the sun reflecting off the water is intense. Apply sunscreen before boarding.
