The currency in Katelios is the Euro. As this resort is located in a quiet fishing village, there are minimal foreign exchange facilities and ATMs in the area. We suggest that you buy your travel money before you leave the UK. You can buy Greek currency cheaper online at ThomasCook.com or from any Thomas Cook branch; find your nearest store here. You’ll find a better deal this way than waiting to buy your travel money at the airport. If you’re not sure how much money you want to take away with you, then why not check out the Thomas Cook Cash Passport?
