Leaving behind the white sands and turquoise waters of Koh Rong for the bustling mainland of Sihanoukville marks the transition from island bliss back to Cambodia's fast-developing coastal hub. While the island feels worlds away from the noise of construction and casinos, the journey back is a short but vital link for travelers heading toward Phnom Penh, Kampot, or the airport. The stretch of water between the island and the mainland can be a calm, scenic glide or a choppy adventure depending on the afternoon winds, making your choice of vessel more than just a matter of price.
The route is served exclusively by water transport, with several operators competing to offer the most reliable service. Because Koh Rong has multiple piers, such as Koh Touch and Saracen Bay, it is essential to know exactly where your boat departs from to avoid a last-minute scramble across the island. Booking your tickets through GoAsia.cc ensures you have a confirmed seat on your preferred departure, which is especially important during the high season when the most popular afternoon crossings often sell out.
Koh Rong to Sihanoukville by Ferry
The ferry is the lifeline between the island and the mainland, offering a range of speeds and comfort levels. Prices for this journey typically fall between $15 and $17, depending on the operator and the specific type of vessel you choose. The duration of the trip varies significantly, taking anywhere from 30 minutes on the most direct routes to 90 minutes if the boat makes multiple stops at different piers or neighboring Koh Rong Sanloem before heading to Sihanoukville.
High Speed Ferry
The high speed ferry is the gold standard for this route. These vessels are generally larger catamarans or modern monohulls that provide a more stable ride in rougher seas. If you are prone to seasickness, this is your best bet. The cabins are usually enclosed and air conditioned, providing a cool reprieve from the tropical heat. You can expect to pay around $17 for this service. It is a highly efficient way to travel, especially for those with tight connections for flights or buses in Sihanoukville.
Standard Ferry and Speedboat
Standard ferries and speedboats offer more frequent departure windows throughout the day. The speedboats are smaller and sit lower in the water, which means you will feel the waves more intensely, but they are incredibly fast on calm days. These options range from $15 to $17. While the speedboats are quick, they lack the amenities of the larger high speed ferries, often featuring open-air seating or basic covered areas. If you enjoy the wind in your hair and a more visceral connection to the Gulf of Thailand, these smaller boats are an excellent choice for a quick dash back to the coast.

Tips for Traveling from Koh Rong to Sihanoukville
- Check your pier: Koh Rong is a large island with several distinct areas. Ensure your boat departs from the pier closest to your accommodation, as moving between beaches can require an expensive private longtail boat ride.
- Arrive early: Plan to be at the pier at least 30 minutes before departure. The boarding process can be informal, and boats sometimes depart a few minutes early if all booked passengers are accounted for.
- Protect your luggage: While crew members are generally careful, luggage is often stacked on the deck or in the bow. If it is raining or the sea is choppy, use a rain cover or a dry bag for your electronics.
- Afternoon winds: The sea tends to be calmer in the morning. If you are a nervous sailor, try to book one of the earlier departures before the afternoon chop picks up.
- Onward travel: Sihanoukville is a major transport hub. Once you arrive at the pier (usually the Autonomous Port or GTVC pier), there will be plenty of tuk-tuks and taxis ready to take you to the bus station or the airport. Agree on a price before getting in.
