Kravice waterfalls, Bosnia and Herzegovina. I crawled behind the overgrown vegetation of one of the falls and the walls were covered with iridescent butterflies. Maybe the most beautiful thing I've ever seen.
Sutjeska National Park. Sutjeska is one of Bosnia and Herzegovina's oldest parks. It is famous for the Partisan victory over the Germans in WWII and there are large stone monuments commemorating the event. The park itself is 17,500 hectares of magnificent and untouched wilderness.
