Kep to Siem Reap by Flight via Phnom Penh
You can get from Kep to Siem Reap by combining a bus and a flight.
First, take a bus from Kep to Phnom Penh. Once you arrive in the Capital, head to Phnom Penh Airport and catch a flight to Siem Reap.
Keep in mind that the new airports in both Phnom Penh and Siem Reap are located far from the city centre. Because of this, you won’t save much time compared to travelling overland. This option is also more expensive.
Check the details below to see if this option works for you.
Step 1: Kep to Phnom Penh by Bus
Book a minibus ride online from Kep to Phnom Penh for 43,000 KHR ($11). From the bus station, take a taxi to the new Phnom Penh Airport (Techo International Airport).
The new airport is located quite far from the city centre, so make sure to add at least an extra hour to your travel time. See our page on Phnom Penh International Airport for more details.

Step 2: Phnom Penh to Siem Reap by Flight
Flights from Phnom Penh to Siem Reap cost around 373,000 KHR ($93), and the flight takes just 55 minutes.
Air Cambodia operates two direct flights daily on this route.
Step 3: Siem Reap Airport to the 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.
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, you can take a tuk-tuk or taxi to your hotel.
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).
There are also tuk-tuks from the airport, but they’re slower and not ideal in bad weather. You can read more about all the transport options on our Siem Reap airport page.

Some travellers prefer to make the trip at night to save on a night’s accommodation.
