The itinerary is almost entirely on dirt paths, with some crossings of busy roads, where you need to pay close attention.
Starting from Gallarate near the Mulino Cajello, follow the Strona path (250m) that climbs Mount Diviso (310m) and then descend from the opposite slope and plunge into the Fontanili Oasis, part of the Ticino park where there is a picnic area. From here we proceed through woods of oaks, chestnut trees and Scotch pines to the Oratory of the SS. Cosma and Damiano (12th century) 380m. Going on, you cross the Strona torrent, which from here onwards skirts the path, stopped by the hiker to observe some mills now in ruins, but rich in history.
You pass next to Canale Strona and then reach a lookout point overlooking the Ticino valley. Finally we cross the pineta del Vigano and we reach the river at the bridge of Porto della Torre (Somma Lombardo), dam and hydroelectric plant, along a steep descent. The walk ends near the mouth of the Strona.
*The itinerary is also suitable for mountain biking.
