As Gran Canaria is a Spanish island, the currency used here is the Euro. The island is a popular holiday destination, so you won’t have any problems finding ATM machines or foreign exchange facilities, should you ever need them when you’re there. But in order to get the best exchange rate, our advice would be to buy your travel money before you leave the UK. You can do this either online at ThomasCook.com or by popping into your nearest Thomas Cook store. If you still don’t know how much money you want to take away with you, why not check out the Thomas Cook Cash Passport?
