The currency in Lesbos is the Euro, as it is in the rest of Greece too. It’s possible to withdraw money and pay with your card on the island, but to avoid unnecessary charges, we advise that you exchange your travel money at home before you travel. For the best rates on your foreign currency, pop in to your nearest Thomas Cook store. Alternatively, buy your currency online via ThomasCook.com. However, if you don’t know how much money you want to take with you on holiday, it’s well worth having a look at the Thomas Cook Cash Passport.
