How to Get from Koh Kong to Sihanoukville

Leaving the quiet riverside charm of Koh Kong for the bustling coastal energy of Sihanoukville marks a transition from Cambodia's wild western frontier to its most developed seaside hub. This journey skirts the southern edge of the Cardamom Mountains, offering glimpses of dense jungle and rural villages that feel worlds away from the high-rise casinos and beach resorts awaiting you at the finish line.

While the distance is not immense, choosing the right transport is a balance between your budget and your desire for door-to-door comfort. Whether you are heading to Sihanoukville to catch a ferry to the islands of Koh Rong or simply to explore the changing face of the Cambodian coast, the route from Koh Kong is a straightforward but essential link in any southern Cambodian itinerary.

Koh Kong to Sihanoukville by Bus

For most independent travelers, the bus is the standard way to navigate this route. It is affordable and offers a chance to see the Cambodian countryside through large windows. Booking platforms list two types of vehicles: smaller Coaster minibuses and larger 36-seater coaches, at about $12 to $16 per seat and 5 hours 15 minutes to 5 hours 30 minutes (October 2026).^[1]

Coaster and Seater Buses

The Coaster is a mid-sized vehicle, while the 36-seater offers a bit more interior space.^[1] Most of these buses have air conditioning, though the strength of the cooling can vary, so it is wise to have a light layer handy. You can book your seats for these bus services on GoAsia.cc to have a spot reserved, especially during the busier dry season when coastal routes see an uptick in travelers.

Koh Kong to Sihanoukville by Private Transfer

If you are traveling in a group or simply value the privacy and speed of a dedicated vehicle, a private transfer is the premium choice for this trip. This option removes the need to navigate to a bus station and allows for a direct journey from your hotel in Koh Kong to your specific destination in Sihanoukville.

SUV and Van Options

Booking platforms list private transfers in two sizes: an SUV for up to four people at about $129, and a 7-seat van at about $220 for the entire trip, for example for dive gear or surfboards (October 2026).^[1] The listed duration is about 4 hours 10 minutes, more than an hour less than the bus.^[1] You also have the flexibility to ask your driver to stop for a coffee break or a photo opportunity along the way.
