Island Hopping: Ferryhopper Bookings & Cash Realities on Remote Islands

Greece accepts digital card payments in Athens and major tourist islands like Santorini or Mykonos. However, when traveling by ferry (booked via the Ferryhopper app) to smaller Aegean islands, cash Euro is highly preferred. Family-run tavernas and taxi drivers on remote islands may not accept credit cards. Always keep a sufficient amount of cash. Switch your mobile data profile to the eSIM upon landing and enable Data Roaming to maintain connections.
