Money: The official currency is Nuevo Sol (PEN) divided into 100 céntimos. Visa is the most widely accepted credit card, but all major international credit cards, including Diners Club and MasterCard, are accepted in many, but not all, establishments. Outside Lima facilities may be more limited. Travellers cheques may also be difficult to exchange in small towns and villages, and travellers are advised to have cash on hand. US Dollars are the easiest currency to exchange and plenty of restaurants, hotels and shops in the main cities accept dollars for payment. Casas de cambio (exchange bureaux) often give better rates than hotels and banks and can be found in any town on the tourist circuit. ATMs are available in the main cities.
