In 2026, Croatia is firmly integrated into the Eurozone, and card payments are the primary method for most transactions in cities like Zagreb, Split, and Dubrovnik. Contactless technology is ubiquitous in hotels, major restaurants, and supermarkets. However, you should still carry a small amount of Euro cash for specific "offline" scenarios. Small souvenir stalls, local bakeries (pekara), and rural transport on the islands often remain cash-only. Additionally, while tipping on a card is becoming more common, cash is still the preferred way to show appreciation at local cafes. If you venture into smaller coastal villages or remote mountain regions, you may find that the "cash is king" mentality persists. A good rule of thumb for 2026 is to use a travel-focused credit card with no foreign transaction fees for 90% of your spending, while keeping about €50 in small bills tucked away for local markets or the occasional "cash-only" gelateria.
