Zenica Summer Fest in Zenica
A free, roughly ten-night open-air concert series filling Kamberovica Polje field in Zenica each August, with one evening moving to Vranduk's medieval fortress for a dedicated rock night. Draws mostly regional and family crowds rather than international festival tourists, with daytime children's activities alongside the nightly main-stage program.
Kamberovica Polje, an open field on Zenica's edge, hosts free nightly concerts for about ten days each August, and the run has grown into one of the largest open-air music programs in Bosnia and Herzegovina.
