Trail F4, from Val Fondillo to the pass
The path that climbs from Val Fondillo to the pass, in the Valle Fredda beech forest: cool in summer, scenic in autumn.
The route
What to expect
The F4 connects the Val Fondillo to the Forca d'Acero pass, crossing the Valle Fredda. It's a hiking trail (E) and requires a good level of fitness.
The shade of the forest makes it a great summer trail for walkers and runners. In autumn, the beech forest turns colorful and the path changes appearance.
