Cambodia travel guide

Getting there

International flights arrive at Phnom Penh and at Siem Reap's newer Angkor airport, both well connected to regional hubs. Land borders link Cambodia with Thailand, Vietnam and Laos, but check the latest status, as crossings can close at short notice.

Best time to visit: Nov–Mar – dry season with cooler temperatures.

Tougher months: March–April for intense heat, or September–October when the heaviest rains can flood rural roads.

Typical daily budget: about US$25–40 for a backpacker and US$60–120 mid-range, per person.

Money and safety

Currency: Cambodian riel (KHR). Currency and plug checker.

Tipping: Not required, but small tips for guides and drivers are appreciated.

Emergency numbers: 117 police · 118 fire · 119 ambulance.

• US dollars are used alongside the Cambodian riel; prices are often in dollars, with change under a dollar given in riel.
• ATMs are widespread in towns and dispense dollars, but torn or worn notes may be refused, so check your change.
• Bag snatching from passing motorbikes happens in Phnom Penh – hold phones and bags on the side away from the road.
• Never stray off marked paths in remote rural areas, as landmines and unexploded ordnance remain in some regions.
