Siem Reap to Phnom Penh by Bus
Giant Ibis covers the 320 km in about 6 hours from its terminal behind the Old Stadium near Khmer Pub Street and arrives at its station on Street 106 (Night Market) in Phnom Penh.[1] Night buses have double and single bunks, a pillow and blanket and an onboard toilet, with no bathroom stops but a 15-minute driver swap in Kampong Thom. Complimentary pickup is currently not available for night departures.[1]
Booking platforms list buses from several companies at about $8 to $20 and journey times of 5 hours to 6 hours 30 minutes (October 2026).[2]
Siem Reap to Phnom Penh by Van
Minivans are an alternative to a large coach. Booking platforms list seats at about $13 to $17 and journey times of 5 hours 30 minutes to 6 hours (October 2026).[2] Vans generally have limited luggage space, so check the requirements if you carry a large suitcase.
Siem Reap to Phnom Penh by Flight
Flying is the quickest option. Air Cambodia and Cambodia Airways operate between Phnom Penh Techo International and Siem Reap Angkor International, and the scheduled time in the air on the Siem Reap airport board for 15 October 2026 was about 1 hour.[3] All Phnom Penh airport operations moved to Techo International Airport on 9 September 2025, so allow time for the transfer between the airport and the city.[4] Fares vary by date, so compare them on the airlines' sites.
Siem Reap to Phnom Penh by Private Transfer
A private vehicle gives you door-to-door service, your own departure time and stops for photos or snacks. Booking platforms list private cars and vans from about $93, with journey times of 5 to 6 hours (October 2026).[2]

Tips for Traveling from Siem Reap to Phnom Penh
- Book in Advance: During peak season and local holidays such as Khmer New Year, buses and flights fill up quickly. Secure your tickets early.
- Pick-up: Some companies offer hotel pickup in Siem Reap, but Giant Ibis does not currently provide it for night departures, so confirm at booking.[1]
- Luggage Safety: Keep your passport, money and electronics in a small daypack that stays with you, not in the luggage compartment under the bus.
- Arrival in Phnom Penh: Giant Ibis arrives at its station on Street 106 (Night Market), and tuk-tuks wait outside.[1] Have your hotel's address ready on a map to show the driver.
