The short answer is Cards are widely useful, but carrying some euros is sensible for small purchases, transport, tips, rural stops, and situations where a terminal is unavailable.
Why this question matters
Payment is usually easy in cities and established tourist businesses, while island and small-village logistics can be more variable.
Quick planning answer
Use cards for planned spending and a modest cash reserve for the parts of the route that are less predictable.
What to check before booking
- Carry a backup card and small cash
- Use official ATMs and check fees
- Keep cash for buses, ferries, and small tavernas when needed
A practical way to decide
1. Start with the part of the trip that is least flexible: the flight, ferry, remote activity, school holiday, or fixed event. 2. Compare the full door-to-door route, including check-in, luggage, walking, waiting, and the final connection. 3. Keep one fallback that protects your sleep, safety, budget, or most important experience.
