Vertical Challenge offers speleology routes in different caves of the Geopark Orígens for all ages and ability levels. The Forat la Bou is an ideal cave to do with the family. It’s located above the quaint village of Serradell, where uneven erosion on the Oligocene conglomerates has resulted in incredibly unique and beautiful shapes carved in the mountains that surround the valley, such as the locally known “picorres”.
