Leaving the chaotic charm of Phnom Penh for the white sands of Koh Rong feels like stepping into a different version of Cambodia. While the capital hums with the sound of thousands of motorbikes and the echoes of a complex history, Koh Rong offers a total reset. It is a place where the jungle meets the Gulf of Thailand, and the only schedule you need to follow is the rhythm of the tides. The express highway to the coast has cut the road leg to about 4 hours by bus.[1]
Getting to the island takes two legs: a road trip from the capital to the coastal city of Sihanoukville, followed by a boat crossing of about 45 minutes from Sihanoukville Pier.[2] Many travelers book a combined ticket that covers both legs, which makes the transfer at the pier easier. You can easily browse and book these combined tickets on GoAsia.cc to secure your spot, especially during the busy dry season when boats fill up quickly.
Phnom Penh to Koh Rong by Bus
The bus is a reliable and popular choice for those looking for a balance between price and comfort. Large buses offer more room than minivans, which helps if you have large suitcases or simply prefer a bit more personal space.
When you book a bus option, you are typically choosing between a standard bus plus ferry combination or a dedicated minibus service. On booking platforms, bus and ferry combinations list at about $32 to $46, with a total travel time of 4 hours 30 minutes up to 9 hours (October 2026).[3] Giant Ibis, which runs its own bus to Sihanoukville, gives the road leg as 4 hours via the express highway, with a 30-minute rest stop halfway.[1] The longer totals usually come from a longer wait for the ferry departure in Sihanoukville.
Bus and Ferry Combinations
Choosing the bus and ferry combo is the most seamless way to travel. You depart from Phnom Penh in a large vehicle, arrive at the Sihanoukville pier, and are directed to the next available boat, which takes the guesswork out of navigating the busy port area.
Phnom Penh to Koh Rong by Van
For travelers who want to reach the beach as quickly as possible, the minivan is the preferred mode of transport. These smaller vehicles are often faster at navigating traffic. Larryta, for example, runs a 15-seat minivan to Sihanoukville via the express highway in 3 hours 30 minutes for KHR 60,000.[4] Seats can feel snugger than on a full-sized bus.
Vans on this route are sold as a minivan plus ferry connection. On booking platforms, the whole journey to the island is listed at 4 to 6 hours and about $41 to $48, with departures between 07:30 and 11:00 (October 2026).[3] A morning departure leaves enough daylight to find your bungalow on Koh Rong.

Tips for Traveling from Phnom Penh to Koh Rong
- Book in Advance: Koh Rong is Cambodia's most popular island destination. During weekends and holidays, both the vans and the ferries can sell out. Booking your combined ticket a few days early is highly recommended.
- Know Your Pier: Koh Rong has several beaches and villages, among them Koh Touch, Sok San and Long Set.[5] Check with your accommodation which pier is closest. Direct boats to Sok San run only occasionally; otherwise you change at the main Koh Rong pier and take a shuttle boat.[6]
- Sea Conditions: Tourist boats between Sihanoukville and the nearby islands sometimes sail despite weather warnings, and accidents have happened with overloaded or poorly maintained boats.[7] If you are prone to seasickness, consider taking medication before boarding.
- Cash is King: There are no ATMs on the island, so carry enough US dollars from the mainland.[2] Smaller businesses and bars are often cash only.
- Sun Protection: The sun on the open water is intense. Keep your sunscreen and a hat in your carry-on bag.
