The normal way to travel from Phnom Penh to Siem Reap is by direct bus or coach. It is inexpensive, runs throughout the day and takes you from city to city without airport transfers. Flying is much faster in the air, while a private car gives you more control over stops and departure time.

Prices and schedules change. Check live schedules, current fares and ticket availability for your travel date.
The normal choice: take a direct coach
The road between Phnom Penh and Siem Reap is straightforward and direct coaches make the trip easy. A current Giant Ibis route guide gives a planning time of about 6 hours for the roughly 320 km journey. Other operators use the same corridor, so the exact departure point and travel time depend on the service you choose.
Most tourist-oriented buses use central offices or dedicated boarding points rather than a single universal bus terminal. Check the boarding address on your ticket and allow extra time for Phnom Penh traffic. In Siem Reap, operators commonly arrive close enough to the central area that a short tuk-tuk or app ride finishes the journey.
For this distance, paying a little more for a comfortable coach is usually money well spent. The road is long enough to notice cramped seating, but short enough that an overnight service rarely offers much advantage.
Phnom Penh to Siem Reap by plane
Nonstop flights operate between Techo International Airport (KTI) and Siem Reap-Angkor International Airport (SAI). Current schedules show a flight time of roughly one hour.
The headline time is only part of the calculation. KTI is outside central Phnom Penh and SAI is well east of Siem Reap, so airport transfers and check-in can remove much of the time saved compared with a coach. Flying becomes more attractive when you have a tight itinerary or a fare that makes sense after baggage and transfers.
Phnom Penh to Siem Reap by private car
A private car normally takes around five to six hours depending on traffic and stops. It is the easiest option for a family or small group that wants hotel pickup, a flexible departure and the ability to stop for food or a break without following a bus schedule.
Prices vary too much by vehicle and pickup arrangement to give a useful fixed quote. Confirm whether tolls, waiting time and hotel drop-off are included before agreeing to the fare.
Which option should you choose?
- Choose the direct coach for the easiest balance of price and convenience.
- Choose the flight if the air schedule saves enough time after airport transfers.
- Choose a private car when door-to-door travel and flexibility matter more than cost.

Normal Things to do in Siem Reap
Siem Reap is built around visitors to Angkor, but the town is worth a little time of its own. The Old Market and riverside area are useful first anchors, with restaurants, cafés and tuk-tuks close at hand. Angkor Wat, Bayon and Ta Prohm are the obvious temple priorities, and starting early makes the heat easier to handle. For accommodation, staying around the Old Market, Wat Bo or the streets between them keeps evenings simple and gives you plenty of food choices without needing transport every time you leave the hotel.

Practical tips
- Keep small US-dollar notes or Cambodian riel for minor expenses, but check the condition of dollar notes before accepting them.
- For Angkor days, agree on the route and price with your driver before leaving town.
- If flying, allow for the transfer time to and from both airports rather than comparing flight time alone.
