Jelen OK Fest returns to Tjentište, in the heart of Sutjeska National Park. From July 17 to 19, 2026, one of the region's most recognisable festivals stages three days of music in a mountain setting, with a line-up that blends rock, electronica and international names.

For years OK Fest has been a festival with a character of its own - not just because of the music, but because of its location among the mountains and forests of Sutjeska. Among those announced for the 2026 edition are Skunk Anansie, The Wailers, Joss Stone, Senidah, Zoster, Gobline and many more, with a dedicated electronic programme featuring regional and international DJs.

The mix of mountain setting, camping and a varied line-up sets OK Fest apart from urban festivals. For many visitors from across the region, this is one of those summer gatherings you don't miss, drawing crowds from all over the former Yugoslavia.

Tickets are sold through entrio.hr. The event takes place at Tjentište, in Bosnia and Herzegovina, for readers planning a summer trip.
