Long and wonderful tour developing in its first stretch on the large and woody northern slope of Mt. Colma, then along the ridge, densely covered with chestnut tree woodlands at first, and then opening in beautiful views.
Very recommended itinerary, especially if you are carrying out the traverse to Capanne di Marcarolo with itinerary C1, completing in this way the whole route of the left watershed of Valle del Piota, marking the Park borders.
