- Visa
- Most EU, US, UK, Canadian, and Australian travelers need a tourist visa for Cambodia. The official e-Visa costs USD 30, is single-entry, and allows a 30-day stay; visa on arrival is still available at Techo International Airport in Phnom Penh, Siem Reap-Angkor, and Sihanoukville. Submit the Cambodia e-Arrival card at arrival.gov.kh within 7 days before flying.
- Currency
- Cambodia runs on two currencies at once: the official one is the riel, but US dollars are used for hotels, transport, tours, and plenty of restaurant bills. Bring clean, untorn USD notes, because damaged bills are often refused, and expect small change in riel at roughly 4,100 KHR to 1 USD. Cards work in better hotels and upscale restaurants, but cash still does the real work.
- Getting There
- Most long-haul travelers reach Cambodia with one stop in Bangkok, Singapore, Kuala Lumpur, Ho Chi Minh City, Hanoi, Seoul, or Guangzhou. The main international gateways are Techo International Airport for Phnom Penh, Siem Reap-Angkor for the temples, and Sihanoukville for the coast and islands. Cambodia is easy to reach by air; it is not a country you plan around international rail.
- Getting Around
- Buses and minivans still carry most travelers between Phnom Penh, Siem Reap, Battambang, Kampot, and Kep, while domestic flights save time on longer hops to Sihanoukville and back. Royal Railway is slow but useful on the Phnom Penh to Kampot to Sihanoukville line and on the route toward Battambang. Ferries from Sihanoukville are the standard way to reach Koh Rong.
- Climate
- Cambodia has two real seasons, not four. Dry season runs from November to April, with the most comfortable weather from November to January; wet season runs from May to October, when heavy afternoon rain turns the countryside bright green and the Tonle Sap swells dramatically. March and April are the hardest months for heat, often pushing 38 to 40C.
- Connectivity
- Mobile data is easy to get in Phnom Penh, Siem Reap, Kampot, and other main traveler hubs, and hotel or cafe Wi-Fi is usually good enough for route planning and calls. Card payments are still patchy, but QR payments are common among locals through ABA and other Cambodian banking apps. Short-stay visitors should treat cash as the default and data as easy.
- Safety
- Cambodia is manageable for independent travelers, but road safety is the thing to take seriously. Night buses, overloaded minivans, and casual scooter rentals cause more trouble than petty crime, especially outside the main cities. Keep an eye on official border advisories, carry small bills, and use reputable transport between towns.
Carry clean dollars
Bring small USD notes in good condition. Torn, stained, or heavily creased bills are often rejected, even when the amount is low.
Use rail selectively
Royal Railway is good when you want a slow daylight ride between Phnom Penh, Kampot, and Sihanoukville, or toward Battambang. It is not the fastest option, so check schedules before building a whole day around it.
Book peak season early
Reserve Siem Reap and Phnom Penh stays early if you are traveling between December and January. Angkor season fills the better mid-range hotels first, and the late-booking bargains shrink fast.
Pay for the better bus
Spend a little more on reputable operators for intercity routes, especially after dark. The cheapest minivan is often where Cambodia's road-safety problem becomes your problem.
Tip with context
Restaurants do not require tipping, but rounding up or leaving 5 to 10 percent for good service is normal if no service charge is already on the bill. Guides and private drivers expect tips more than cafe staff do.
Download before islands
Mobile data is easy in cities, less predictable once you are on boats or beaches. Download tickets, maps, and hotel details before leaving Sihanoukville for Koh Rong.
Respect temple etiquette
Dress modestly for temples and active religious sites: shoulders covered, shorts below the knee if you can manage it. Cambodia is relaxed in plenty of ways, but monks and shrine spaces still run on visible respect.
