The currency used in Koukounaries is the Euro. There aren’t any ATMs in Koukounaries itself, so you’ll need to take a trip to Skiathos Town if you need to draw out more cash while you’re away. We recommend exchanging plenty of money before you travel to save yourself this hassle, which you can do at Thomas Cook stores or online. If you have some Euros left over, you can just use them on your next European adventure.
