Barranc Fondo Route
A walk along the Barranc Fondo ravine follows the River Mezquín as it cuts through wide expanses of farmland. Although the visit to this natural space can be started at different points, we have chosen a stretch starting in Torrevelilla that takes you to the neighbouring village of Belmonte de San José. It coincides with the route of the scenic trail PR-TE 13.
