Yes, Cambodia operates on a highly unique dual-currency economy utilizing both the US Dollar (USD) and the Cambodian Riel (KHR) interchangeably everywhere.

ATMs dispense US Dollars, and major prices (hotels, tours, large restaurant bills) are quoted in USD. However, change for anything under $1 or $5 is almost always given back to you in Cambodian Riel. Important Note: Ensure any US dollar bills you bring are crisp and completely untorn; merchants and banks will strictly reject bills with even tiny rips, marks, or deep creases.

Yes, conquering the Angkor temples requires preparation, including purchasing an official Angkor Pass (available for 1, 3, or 7 days). Because the archaeological park is massive, hire a dedicated tuk-tuk driver for the day through your hotel.

Dress Code: As this is an active, highly sacred religious site, the dress code is strictly enforced. Shoulders and knees must be covered for both men and women. Guards will deny entry to visitors wearing tank tops or short shorts, even if you try to wrap a scarf around yourself.

The most efficient way to travel around is by traditional *remorque* (a carriage pulled by a motorbike) or the modern three-wheeled auto-rickshaw, which remain the primary modes of transport in Cambodian cities. To completely avoid the hassle of street haggling over fares, immediately download ride-hailing apps like PassApp or Grab to your smartphone. They provide fixed, incredibly cheap fares for tuk-tuks directly from your phone.

Yes, Cambodia is generally very safe for tourists. Violent crime against travelers is extremely rare. However, like in many global destinations, visitors should be mindful of petty theft, such as bag snatching, particularly in busy areas of Phnom Penh and crowded markets.

Yes, the vast majority of foreign nationals require a visa to enter Cambodia. You can easily obtain a 30-day tourist e-Visa online prior to arrival, or get a Visa on Arrival at major airports and land border crossings. Ensure your passport is valid for at least six months.

No, it is highly recommended to avoid drinking tap water anywhere in Cambodia. Always use sealed bottled water or filtered water for drinking and brushing your teeth. Ice in established restaurants and hotels is generally produced commercially from purified water and is safe.

Yes, the US Dollar is used concurrently with the Cambodian Riel throughout the country. Most restaurants, hotels, and tour operators will quote prices in USD. However, smaller change (under $1 or $5) is almost always given back in local Riel.

The most popular and cost-effective way to travel between major hubs like Phnom Penh, Siem Reap, and Sihanoukville is by VIP sleeper bus or private minivan. Domestic flights are also available and save significant travel time if you are on a tight schedule.
