The BCA bank is quite prominent in SAL and all over Cape Verde.  You can change all currencies in the BCA bank in Santa Maria and in Espargos the capital. LENEESE (in Santa Maria) SPEAKS VERY GOOD ENGLISH AND IS VERY HELPFUL. Save yourself all the problems by taking EUROS, it is the accepted currency. Everywhere takes EUROS and almost certainly they will give you change in ESCUDOS the local currency.

There is an official rate of €1=110escudos set by the government. ATM's. all banks have them most are in PORTUGUES. Just ask one of the Bank staff and they will come out of the bank and assist you (can you believe that).. All travellers cheques and other currencies carry a commission (quite high) and variable. Finally GET RID OF ALL ESCUDOS before you leave the country, unless you intend to return.

VISA CREDIT CARDS! they are just starting to take visa, not in all places but some, and it is expanding rapidly. If you intend to buy or go there often its easy to open an account. Transferring large amounts of money from the UK is easy.

Do not take Travellers Cheques. You could be charged Eu20 for £150 (2 cheques). You'd be much better getting a cash advance on your Visa card. Load up your account before you leave home, and you won't be charged cash advance.

Best to take Euro cash and change it as you go.

If you are going to the the bank, get there early especially after holidays. It really gets busy. The bank staff are very helpful
