Siem Reap lies on the other side of the country from Sihanoukville, so choosing the right transport can decide whether you arrive exhausted or ready to explore. The options range from budget night buses that save a night of accommodation to a direct flight.
You can book tickets for this route on GoAsia.cc to secure your seat before you leave the beach.
Sihanoukville to Siem Reap by Flight
For those who value time over budget, flying is the most efficient option. Air Cambodia flight K6130 from Sihanoukville was scheduled to depart at 13:20 and land at Siem Reap Angkor International Airport (SAI) at 14:30 on 15 October 2026, a scheduled flight time of 1 hour 10 minutes.[1] Sihanoukville's airport is called Sihanoukville International Airport (KOS).[2] Fares vary by date, so compare them on the airline's site.
Flying skips the long hours on Cambodia's roads, but the airport sits outside Siem Reap, so allow time and money for the transfer into town.
Sihanoukville to Siem Reap by Bus
The bus is the quintessential way to cross Cambodia for backpackers and budget-conscious travellers. Giant Ibis lists a night bus from Sihanoukville at 19:00 and from Siem Reap to Sihanoukville at 22:00.[3] The journey takes 11 hours. Night buses have double and single bunks, a pillow and blanket and an onboard toilet, and they make brief stops for the drivers to swap. The bus leaves from the Giant Ibis ticket office on Phe Street next to the Autonomous Port and arrives at the terminal behind the Old Stadium near Khmer Pub Street.[4]
Booking platforms list buses from other companies at about $14 to $48 and journey times of 8 hours to 15 hours for some multi-leg journeys (October 2026).[5]
Combined Ferry and Bus Services
If you come from an island such as Koh Rong or Koh Rong Sanloem, some booking platforms sell a Ferry + Bus ticket from about $14 (October 2026).[5] These services line up your boat arrival with a bus departure, but be prepared for a very long day of travel.
Sihanoukville to Siem Reap by Van
Booking platforms list vans and minivans at about $27 to $30, with journey times of 7 hours 45 minutes to 9 hours 30 minutes (October 2026).[5] Vans can feel cramped when every seat is taken, but they are a good choice for daytime travel.
Sihanoukville to Siem Reap by Private Transfer
A private transfer is the most comfortable way to make the trip if you are travelling as a group or want door-to-door convenience. Booking platforms list private vehicles from about $162, with larger vans and minibuses costing more, and journey times of 7 to 9 hours (October 2026).[5] A private driver lets you schedule your own breaks and avoid crowded bus stations, which suits families and travellers with a lot of luggage.

Tips for Traveling from Sihanoukville to Siem Reap
- Book the Sleeper Early: Night buses are popular and can sell out a few days ahead, especially in the dry season.
- Prepare for the AC: Buses and vans can be heavily air-conditioned, so keep a light jacket or sarong in your carry-on bag.
- Snacks and Water: Giant Ibis night buses make no bathroom stops, so use the facilities before you board and bring your own water and snacks.[4]
- Road Conditions: Traffic and road works can add hours to a long journey. Avoid booking tight connections or tours on the afternoon you arrive by road.
