11. Slavonski Brod
Located in Slavonia in the northeast of Croatia, Slavonski Brod is a pleasant enough if the unspectacular city to visit although it has a nice promenade along the Sava River. The highlight of any trip to the city is the impressive Brod Fortress which is in excellent condition and is very interesting to walk around. Try and visit during mid-June when the city hosts the Brodsko Kolo Festival – a local folk festival which highlights some of the traditions of the region.
