Greece uses the euro. Island hopping and ferry connections mean you should not rely on one remote ATM on a quiet island without a cash buffer.
Islands and mainland
Athens and Thessaloniki behave like any major euro city. On smaller islands, seasonal demand can strain ATMs in peak weeks โ land with some euros already in your wallet.
Tavernas and tips
Service charges vary; rounding up or leaving small change is common. Keep low denominations for beach clubs and boat day trips.
Buy before you fly
Compare euro rates via our main comparison. Sterling-to-euro airport purchases are convenient but usually expensive for large amounts.
