Money in Peru
For travellers from North America or Western Europe, Peru is a very inexpensive country to visit because of the very favorable exchange rates. At the time of writing, the exchange rate for USD was $1 to 2.81 Peruvian soles. The currency is the Nuevo Sol (s/), which comes in coins of 5, 10, 20, and 50 cents, 1, 2, and 5 soles with bills of 10, 20, 50, 100, and occasionally a 200 soles bill.
USDs are not widely accepted, however, most tours are sold in USD and many tourist shops or restaurants will accept them. It is important to often keep small bills of soles with you, as many places, especially outside of city centers, do not have adequate change. In tourist centers Mastercard and Visa are usually accepted, however at small stores and outside of urban areas most transactions are done in cash. There are many ATMs around cities, and in popular tourist areas many are guarded at night to ensure you have a safe transaction.
