Getting local currency
You can purchase Cuban Convertible Pesos at the airport or in banks or money exchanges (cadecas). US dollars are not accepted so you need to take cash in sterling. Euros are also accepted but the rate may not be as favourable.There are some ATM machines which supposedly accept debit cards but they are not always reliable. You can also get cash with a credit or debit card (not issued by a US bank). You can change surplus money back to convertible currencies at the airport at the end of your trip.
