It is also the entrance for both domestic and international departures. First floor is reserved for departing return flights.

Getting to the City from Phnom Penh International Airport (PNH)

You can choose to take either a public taxi at the airport or a private taxi if you book it ahead of time.

Why visit Phnom Penh?

Phnom Penh’s vibrant, busy streets and colourful homes will keep your senses busy as you begin to explore. Since the city is located near the meeting point of the Mekong and Tonlé Sap Rivers, a walk along the Sisowath Quay is a good start. This promenade offers a relaxing environment by the river with three kilometres of vendors, hotels, restaurants, cafes and shops to enjoy. Then visit the Phsar Thmei, a central market located inside a bright yellow, Art Deco building, to purchase local food and goods.
See more examples of beautiful classic architecture in the Khmer-style by visiting the Royal Palace, which is near the banks of a river and surrounded by neatly shaped gardens. The palace is also home to the famous, 5,000-tile Silver Pagoda, also known as the Temple of Emerald-Crystal Buddha. See glimpses of Phnom Penh’s French colonial past in the architecture of the General Post Office and the Commissariat.

Don't Forget Before you Fly

British nationals need a visa to travel to Phnom Penh. However, you can apply for an e-Visa online beforehand or pay a small fee for one upon arrival at PNH. If you decide on the latter option, be sure to take a passport photograph with you. The visa is valid for 30 days, starting with your date of entry. Make sure your passport is stamped and keep the departure form, as you’ll need it to leave the country. It’s advisable to have some Cambodian riel with you when you arrive, although you can also use an ATM to withdraw some cash as well.
