Booking Tip
Sihanoukville to Siem Reap by Flight
Flying from Sihanoukville to Siem Reap is the fastest way to travel, but there is only one direct flight per day. Still, it’s a great option if you want to avoid spending at least 7 hours on the road.
The total travel time, including transfers to and from the airports, is around 2h 30m - 3h 40m. Fares start from 494,000 KHR ($125).
Step 1: Sihanoukville city centre to Sihanoukville Airport
Sihanoukville International Airport (KOS) is located about 25 km from the city centre. There’s no public transport available, so you have two main options for getting to the airport: a private air-conditioned transfer or an open-air tuk-tuk.
If you prefer a more comfortable and faster ride, go for a private transfer. You can take a regular taxi, book a ride through Grab or PassApp, or reserve a car online via BookAway or Camboticket. Prices range from 100,000 KHR ($25) to 120,000 KHR ($30).
Tuk-tuks are a cheaper alternative and offer a more local experience. Fares usually range between 48,000 KHR ($12) and 80,000 KHR ($20). You can find them on the street, but booking through the Grab app often gives you a better rate.
Step 2: Sihanoukville to Siem Reap by Flight
Air Cambodia operates one direct flight daily from Sihanoukville to Siem Reap, with fares starting from 414,000 KHR ($105).
The flight itself takes a little over an hour.
Step 3: Siem Reap Airport to Siem Reap city centre
Siem Reap–Angkor International Airport (SAI) is located about 45 km east of the city centre. Since replacing the old airport in 2023, it now takes longer to reach town — around 45 minutes to 1.5 hours, depending on traffic and your transport choice.
You have three main options to get into the city: airport shuttle bus (1 hour), tuk-tuk (1 to 1.5 hours), and taxi (45 minutes to 1 hour).
The cheapest option is the airport shuttle bus, with fares from 32,000 KHR ($8.00). It drops you off along 7 Makara Street, about 2 km from the Tourist centre. From there, take a tuk-tuk or taxi to your hotel.
Tuk-tuk fares start from 60,000 KHR ($15). They’re not the fastest or most comfortable, especially in bad weather, but they offer a fun local experience. Ride-hailing apps like Grab or PassApp usually offer better rates than negotiating on the spot.
Private transfers are the most comfortable and fastest option, though they’re also the most expensive. You can choose between airport taxis, ride-hailing apps like Grab and PassApp, or pre-booked cars through BookAway. Prices range from 100,000 KHR ($25) to 181,000 KHR ($45).
TIP: If you decide to travel by plane, please consider including a carbon compensation fee to reduce your impact on the environment.
