FAQs about flying to Phnom Penh
Phnom Penh climate
Phnom Penh is a year-round destination which has a tropical wet and dry climate. Temperatures are hot throughout the year, usually between 22 and 35 degrees Celsius, so perfect for those looking for some sun.
Getting around Phnom Penh
Walking around the centre of Phnom Penh is an enjoyable way to get a feel for the city, but to get around the suburbs, travelling by tuk-tuk or taxi is advisable. You can rent motorbikes at a very cheap rate as well, if you are confident about dodging traffic (and don’t forget to rent a helmet as well). However, a more sedate form of local transport is the fleet of three-wheeled cycle rickshaws.
Getting from the Airport to the City
Phnom Penh International Airport (PNH) is located 10 km from the city. For those getting off flights, there will be taxis gathered directly outside the arrivals terminal, and they should charge a flat rate to get you into the city. For an even cheaper ride, leave the airport and catch a tuk-tuk or one of the many motorcycles that will ferry those with less luggage into town. There is also a city bus that will take you straight to the Central Market. If you decide to hire a car during your visit, to make sure a car is available, you may want to reserve the car once you have booked your flights to Phnom Penh.
