ATMs & Cards in Gran Canaria
Using card in Gran Canaria is easy, too. It’s such an established holiday hotspot that there are plenty of ATMs, and we recommend taking a mix of cash and card for convenience and security. If you are planning to use your regular debit or credit card check what fees there are for transactions abroad, these can really mount up over your holiday and leave you with a nasty bill at the end.
