Siem Reap receives flights throughout the evening, and connections from Bangkok, Ho Chi Minh City or Kuala Lumpur can land quite late. A late arrival here is a different proposition than it used to be, for one simple reason.
First: the airport moved
The old Siem Reap International Airport (REP) was 6-8 km from town. It closed to commercial flights on 15 October 2023. Flights now use Siem Reap–Angkor International Airport (SAI), about 50 km east of the city — roughly a 45-60 minute drive on the Angkor Highway.
At the old airport, a late landing meant a fifteen-minute ride and you were at your hotel. Now it is an hour. Anything you read about arriving late in Siem Reap that was written before October 2023 is describing a journey that no longer exists.
Airport conditions after dark
The terminal is modern and stays open and staffed for arriving flights. Immigration operates as normal, though queues can be slow if one officer is processing a full flight. ATMs work. SIM card counters may be closed later in the evening, so if you are counting on mobile data for a ride-hailing app, that is a plan with a hole in it — pick up a SIM earlier in your trip or arrange transport in advance.
Transport availability at night
Transport counters in arrivals: Staffed for arriving flights, with rates posted. This is the reliable walk-up option — a fixed price agreed indoors rather than a negotiation in the dark, which matters more when the journey ahead is 50 km rather than 8.
Airport shuttle bus: Runs to a schedule, so check whether it is still operating for your arrival time before you count on it.
Grab / PassApp: Availability drops off at night, and at 50 km from the city it was never dependable to begin with. Response times lengthen and cancellations increase. Do not make this your only plan for a late landing.
Pre-booked transfer: The most reliable choice for a late arrival. Your driver tracks the flight and is there regardless of delays or the hour. Nothing to arrange, nothing to negotiate, and no 50 km problem to solve at midnight.
Tuk-tuks: Not for this journey, and especially not at night. It is a 50 km highway run in an open vehicle.
The drive into town at night
The route is the Angkor Highway, a modern purpose-built road, and it is straightforward after dark. Traffic is minimal at night, so the drive is at the quicker end of the 45-60 minute range.
Siem Reap is a safe town for tourists by regional standards. The concern with a late arrival is not crime — it is the combination of distance, fatigue and reduced transport options. Being stranded at an airport 50 km from your hotel at 1 AM is an inconvenience worth designing out in advance.
If your hotel offers pickup
Many hotels arrange airport pickup and most will accommodate late arrivals if you tell them in advance. Given the new distance, this is worth asking about directly — and worth asking what it costs, which is a real question now in a way it was not when the airport was fifteen minutes away.
Send your hotel your flight details before departure, confirm the driver's name and phone number, and you have a backup if the driver is not immediately visible when you exit.
A note on prices
We do not quote figures for this journey. The airport does not publish its ground-transport fares, and the numbers on travel sites contradict each other — most are the old airport's prices for a much shorter trip. The rates are posted at the transport counters in arrivals; that is the number to trust. Late-night premiums, if any, will be reflected there.
Practical tips for late arrivals
Withdraw cash from the terminal ATM before you exit — small US dollar bills are the most useful. Have your hotel address saved offline and your phone charged. If you did not pre-book, the transport counter in arrivals is your fallback, and a better one than walking outside to see what turns up.
The simple answer
For a late arrival, pre-book your transfer or confirm a hotel pickup before you fly. This is not about safety — Siem Reap is welcoming and straightforward. It is that the airport is now an hour from town, and that is not a variable you want to be improvising with at the end of a long flight.
