The mount Martica dominates the western slope of the Valganna, with the remains of discovered artillery stakes, built within the Northern Frontier. The route starts from the clearing beside the SS233 where it is possible to park ( Saint Gemolo farmhouse) following the signs for the now abandoned Valvassera Mine. The path proceeds up to a picnic area located a few meters from the river, adventurous people can discover the little-known Valvassera Falls, reachable only by a short walk in the river bed.
