Cambodia Currency
The local currency is the Riel. However, US$ are widely accepted and easily exchanged across the country. In Phnom Penh and other towns most goods and services are priced  in dollars and there is a little need to buy riel.  In remote rural areas prices are quoted in riel
(except accommodation). In western districts, particularly Poipet,  Pailin and Koh Kong the  Thai Baht is widely used. Traveler's cheque's in US$ can be changed at most banks in 
Phnom Penh  and major tourist destinations. Credit card facilities are limited to some major  hotels. It is best to carry US$ in cash in small denominations.
