Temple Dress Code: When visiting the temples of Angkor and other sacred sites, modest dress is mandatory. This means covering your shoulders and knees. Always carry a sarong or scarf to ensure you can enter all venues.

Double Currency (Dollar and Riel): Cambodia uses a dual currency system. US dollars are used for almost all transactions (accommodations, restaurants, tickets). The Cambodian Riel (4000 KHR ≈ 1 USD) is mainly used as exchange for amounts less than one dollar. Make sure you bring dollars in good condition and small denominations.

Common scams: Beware of the 'milk powder scam'. Often, women with babies will ask you to buy them a can of powdered milk from a specific store at an inflated price. Then, they return the can to the store and split the money with the owner. It is better to donate to reputable local NGOs if you want to help.

Water and Food: Always drink bottled water and avoid ice in places with dubious reputations. Street food is delicious and generally safe, but choose busy stalls and where you can see the food being cooked to order. It is not necessary to be excessively afraid, but it is necessary to take basic precautions.
