Just like the rest of Greece, the currency in Corfu is the Euro. You’ll find plenty of ATMs throughout the main towns on the island, but it’s useful to have a small amount of cash before you leave, so you don’t spend the first few hours of your holiday looking for a bank or ATM.
A mix of cash and card gives you a little extra security and convenience. You’ll find your debit or credit card is accepted in many places, but cash is often preferred and helps keep things simple for independent businesses. It’s worth investigating what your bank charges for transactions abroad too, as these fees can mount up and give you a nasty shock at the end of your holiday.
