Hiking
A very short stage characterized by a descent leads to the road pass of Colle di Nava. The route faithfully follows the watershed between Val d'Arroscia to the south and Val Tanaro to the north, passing by Bocchino di Semola and Colla di San Bernardo before reaching the pass. We are in a strategically important area from a military perspective where, starting from the 19th century, a complex line of fortifications was built, including the Central Fort located in the village.
