This short stage, but with a significant elevation gain, leads to the heart of the Park at the shelter located at the foot of the highest peaks in the area, particularly Monte Cervati, which stands at 1,899 meters. After an initial flat section that runs alongside the plain where the village of Sanza is situated, the path turns sharply north and enters the Vallone Secco, which is followed in its entirety, ascending until it reaches the welcoming shelter at an altitude of 1,597 meters where you can spend the night.
