Phnom Penh essentials

Visas and arrival

Cambodia’s official e-Visa portal is evisa.gov.kh: look-alike sites charge extra, so type the address yourself. Air travellers are asked to complete an arrival card online before they fly; check the current rule with your airline and your government’s travel advice.

Fees and eligibility change: we print only what the official portal shows on the day you apply.

From the airport

Techo International Airport has handled Phnom Penh’s airline flights since 9 September 2025, replacing the old airport. It lies around 20 kilometres south of the city (ocic.com.kh). Arrange a hotel car, or use the official transport options listed on cambodia-airports.aero.

Dollars and riel

US dollars and Cambodian riel are both used; small change usually comes in riel. The Tuol Sleng museum, for example, takes cash in either currency (tuolsleng.gov.kh). Carry clean, undamaged notes.

When to go

The cooler, dry months from November are the most comfortable for walking; the hottest weeks come before the rains, and the wet season brings heavy afternoon downpours. Plan sightseeing for early morning and late afternoon.

Overland to Thailand

Overland crossings between Cambodia and Thailand are suspended at the time of writing (28 October 2026). Fly between Phnom Penh and Bangkok, and check your government’s travel advice before planning any overland journey.

Customs and etiquette

Cover shoulders and knees at the Royal Palace and in temples, take off your shoes where others do, and never touch a monk or a person’s head. At Tuol Sleng and Choeung Ek, arms and legs must be covered and visitors keep their voices low.

Emergencies

The UK government’s travel advice lists Cambodia’s emergency numbers as police 117, fire 118 and ambulance 119. See our health page for hospitals. Carry travel insurance that covers medical evacuation. In tuk-tuks and on foot, keep bags and phones away from the roadside.
