The 75 km road from Sarajevo to Foča is very scenic.
Foča is a good base to explore nature from. For example, to go rafting on the Tara river, running through the deepest canyon in Europe, or go hiking through Perućica forest, one of the last ancient forest left on the continent, with trees measuring up to 60 meters. Also a challenge is to try to climb the Maglić mountain, right on the border with Montenegro. Maglić ("fog") is the highest peak of BiH, and besides with a guide you probably need two days to reach the peak.
