Currency: Cuban Convertible peso (CUC).
Due to the recent regulations established in Cuba related with the
circulation of the USD in cash, from date November 8th 2004, all
payments in cash should be done in CUC (Cuban Convertible peso).
US Dollars in cash won't be accepted as a payment for any service
(hotels, restaurants, taxis, shops, cinemas ect) in the island.
The CUC (Cuban Convertible peso) can be acquired in any Exchange
Houses available in the country or in the Banks.
When leaving the country, the remaining CUC can be changed in the
Exchange Houses available at the Airport. Any other currency in
cash, can be changed to CUC considering the current exchange rate
Cuban pesos, or moneda nacional, can be used at local venta libre
stores, cafeterias and street stands, cinemas, and many other
businesses away from popular tourist destinations. Cadeca, with
kiosks throughout Cuba, changes currency at fair rates.
Credit cards or traveller checks issued by US companies are not
accepted. A Visa or MasterCard (or two) issued by a non-US bank
is the way to go.
