Going up to the Vallecorsa pass, the climb starts 6 km before the built-up area. First you climb gently and then tackle a steeper stretch followed by a 3 km descent that leads us to overcome the Vallecorsa village. The last 5.60 km of ascent leading to the pass alternate gentle slopes with a more challenging central stretch. From the top of the pass, at 530 m asl, you can admire a beautiful panorama that is an excellent reward for the effort.
