Cambodia: main airports
Cambodia has three international airports: Techo International Airport in Phnom Penh, the capital, Siem Reap-Angkor Airport, gateway to the Angkor temple complex, and Sihanoukville Airport, on the Gulf of Thailand coast.
Cambodia: recommended activities
Cambodia: visa and entry requirements
Most nationalities (European Union, United Kingdom, United States, Canada, Australia) can get an e-visa online in advance or a visa on arrival at the airport, both generally valid for 30 days. The visa on arrival must be paid in cash, in pristine US dollar banknotes (not creased or old ones, which are often refused). The passport must have at least 6 months of remaining validity and a blank page.
Cambodia: safety
Cambodia is generally safe for tourists in the main areas (Phnom Penh, Siem Reap, Angkor), with the usual precautions against petty theft and motorbike bag-snatching in crowded areas. Traffic requires attention, especially when crossing roads in large cities. In remote rural areas, landmine remnants from the war period persist: never leave marked paths off well-trodden tourist routes.
Cambodia: health situation
A yellow fever certificate is required only for those arriving from a country at risk of transmission. Routine vaccinations plus hepatitis A and typhoid are generally recommended. Dengue risk is present year-round: mosquito protection is recommended. Drink only sealed bottled water. Phnom Penh's private health facilities are adequate for common emergencies; for complex cases, transfer to Bangkok is common: insurance with possible evacuation is advisable.
Cambodia: currency, payments and connectivity
The US dollar is effectively the main currency for larger purchases (hotels, restaurants, tours), while the Cambodian riel (KHR, about 4,000 per dollar) is used for the rest: bring dollars in $10 and $20 denominations and some riel for small purchases. The riel is not exchangeable outside Cambodia. Credit cards are increasingly accepted but cash remains preferred in most situations. Grab (the Asian equivalent of Uber) operates in Phnom Penh and Siem Reap. For connectivity, the operators Cellcard, Smart and Metfone sell prepaid tourist SIM cards. For driving, an International Driving Permit (IDP) is generally also required, although most visitors rely on tuk-tuks and local drivers.
