The Una Regatta
The International Tourist Una Regatta is a multi-day descent of the Una in boats, kayaks and rafts, from Martin Brod via Bihać to Bosanska Krupa. It takes place every July and is one of the longest-running tourist events in Bosnia and Herzegovina. You do not need to be an experienced paddler to enjoy it: many visitors simply watch from the banks.
The 52nd edition, held from 22 to 25 July 2026, gives an idea of the format: an opening ceremony at the Lučica camp near Martin Brod, then a stage from Martin Brod via Kulen Vakuf to Štrbački buk, a stage from Štrbački buk via Ripač to Bihać, and a final stage from Bihać to Bosanska Krupa. Around 300 people took part in the first stage. In Bihać the fleet is traditionally welcomed at Beton, the swimming spot in the town centre.
Dates for 2027 have not been officially published yet. Plan for the second half of July and watch for announcements from Una National Park and the City of Bihać.
Bihać Summer festival and other events
The Bihaćko ljeto (Bihać Summer) performing arts festival runs every summer. Its 28th edition, from 19 June to 5 July 2026, had nine plays, three concerts, an exhibition and a book launch, with theatres from Mostar, Sarajevo, Belgrade and Zagreb. Most plays cost 10 KM; children’s shows, concerts and the exhibition were free. KM, the convertible mark, is the local currency.
Gradska otoka, the town island, is the summer hub: it has hosted Bihać Summer Fest and the regatta reception. The 2027 programme has not been announced.
Rafting and swimming
Summer is the main rafting season. Tours, camps and gentle sections for beginners and families are covered on our Una rafting page and in the rafting FAQ.
In town you can swim at Beton, Amerikančevo, Hatinac, Brvice and Plandište, all within walking distance of the centre; see the swimming FAQ. Inside Una National Park swimming is only allowed at marked spots.
Evenings by the river
When the heat drops, life moves to the riverbanks: a walk through the town park and along Gradska otoka, dinner by the water or a drink on a terrace. See our guides to restaurants and nightlife.
Practical tips
- Book early: regatta week and August weekends are the most requested dates.
- Heat: Bosnia’s Federal Hydrometeorological Institute recorded July 2025 in Bihać about 1.4 °C above the long-term average. If you sleep badly in heat, choose air conditioning or a house by the river.
- Go early: visit Štrbački buk and Martin Brod in the morning, before the heat and larger groups.
- Insects: bring repellent for evenings by the river.
- Cold water: even in August, get into the Una slowly.
- Border: if you arrive via Croatia, see border and documents and weather and seasons.
