Leaving the white sands of Koh Rong for the ancient spires of Angkor Wat is a trip from Cambodia's barefoot island life to its historical heart. The journey spans the length of the country, from the turquoise waters of the Gulf of Thailand through the hub of Sihanoukville to the dusty, vibrant streets of Siem Reap.
The route combines a boat crossing with a long overland drive. The island has no bridge to the mainland, so every trip starts with a ferry or speedboat to Sihanoukville, a crossing of about 45 minutes.[1] From there you continue by van or bus. Booking a combined ticket on GoAsia.cc helps align the ferry arrival with your onward departure.
Koh Rong to Siem Reap by Van
The van is the most efficient way to bridge the coast and the temple city. These services are typically sold as a combined ticket, with the ferry from Koh Rong timed to meet a waiting van at Sihanoukville. On booking platforms, tickets cost about $32 to $49 (October 2026) and the total journey takes from about 8 hours 45 minutes to 10 hours, depending on road conditions and stops.[2] Space can be tight when the van is full. It is the best balance of speed and price if you want to reach your Siem Reap hotel before late evening.
Koh Rong to Siem Reap by Ferry and Bus
If you want more legroom or prefer to travel overnight, a ferry plus bus ticket is a solid alternative. Booking platforms list these at about $36 to $46 (October 2026), with total journeys of about 9 to 13 hours 15 minutes.[2] Giant Ibis runs an overnight sleeper bus between Sihanoukville and Siem Reap.[3]
Daytime Bus Services
Daytime buses let you watch the countryside roll by, with local villages and palm-fringed landscapes passing the window. They are often large coaches with reclining seats, a steadier ride than a van, and they usually have more luggage space.
Overnight Sleeper Options
If you want to save a night of accommodation, ferry plus sleeper tickets are listed on booking platforms.[2] You arrive in Siem Reap in the early hours, ready for a sunrise over the temples.
Koh Rong to Siem Reap by Ferry Package
When a booking platform shows a "Ferry" option for the whole route, it is a multi-modal package: the boat ride followed by one or two van transfers, for example a change of vehicle in a hub such as Phnom Penh. These packages cost about $39 to $51 (October 2026) and take from about 9 to 15 hours.[2] The advantage is that one operator manages the whole chain, so a late ferry does not leave you stranded.

Tips for Traveling from Koh Rong to Siem Reap
- Book in Advance: This is one of the most popular long-distance routes in Cambodia. In the peak dry season, vans and sleeper buses can fill up days ahead.
- Keep Valuables Close: Large bags go in the hold or the back of the van. Keep your passport, electronics and cash in a small daypack at your feet or on your lap.
- Prepare for the Ferry: The boat ride can be choppy. If you are prone to seasickness, take medication before boarding at the pier.
- Snacks and Water: Rest stops can be unpredictable. Carry enough water and a few snacks for a long day.
- Arrival in Siem Reap: Expect a swarm of tuk-tuk drivers on arrival. Have your hotel name and address written down or saved offline.
