Hrvatska Kostajnica

A town on the Una river at the Bosnian border, watched over by a medieval fortress. It suffered heavy destruction and depopulation during the 1990s war.

Hrvatska Kostajnica sits in Central Croatia, a part of Croatia with its own character, and the city & town is the reason most people stop.

Mornings are quieter and cooler. Most old towns wake up slowly, so an early coffee is worth the effort.

Practical info

• Entry: look up the current price and opening hours before you go. Both change through the year, and a few spots close completely out of season.
• How to get there: Tap the map above for exact directions. In Croatian towns parking is usually signposted and paid, look for the blue P zones. If you are island hopping, leave buffer time for the ferries.

When to go

The best window for Hrvatska Kostajnica runs May to October. June and September balance warmth and thinner crowds; July and August are busy and hot. Out of season, winter shows a calmer, cheaper Croatia that rewards the inland cities.
