Money: Currency exchange rates
The situation regarding Cuban currency is always changing. At the moment, you can use US dollars, the Euro and the Canadian Dollar in major hotels or around the city. There are two currencies used locally: The Convertible Peso known as the CUC, is legal tender for tourists and Cubans. Secondly, there is Cuban National pesos used by the Cuban people but are also legal for use by tourists. Tourists are allowed to exchange their CUCs for Cuban National pesos at official CADECAS.
As for shopping, it is important to realize the United States maintains a broad embargo against Cuba, and most commercial imports from Cuba are prohibited by law.
