The Sp 106 della Baucca begins just on the northern outskirts of Città di Castello and leads to Pietralunga. 15 km of constant ascent with gradually more challenging slopes up to peaks of 14%. It climbs over 700 m near the loc. Perrubbio, but to get to Pietralunga you still have to go up ... watch out for the 🐗🐗 crossing the road!
