There is not a single dish including chestnuts that cannot be found at the Chestnut Festival in Kostajnica. In addition to trying various dishes made of baked and boiled chestnuts and sweets made of delicious chestnut puree, all visitors are invited to take part in the chestnut harvest. This is an opportunity to take a walk through chestnut woods, spend some time in good company, sing a song or two and do all other things guaranteeing a good atmosphere.
