Road access
To reach the starting point, take the A26 motorway following the signs for “Sempione – Confine di Stato” and leave at the exit signposted for Valle Vigezzo. Trontano is just after the town of Masera.

Description of the itinerary
Two hamlets, one lower Cosa and the other upper Cosasca, make up a town hiding a story in which faith and agricultural life are inextricably intertwined. The town is built around a place of sighting used since Roman times. From the bus stop, proceed along Via Rosmini to the Church, then take Via Marconi until returning to the provincial road. Continue north until you reach Via Bellini, continue on that road to the bridge, where you can see a waterfall (11 min). From this point begins an interesting climb along a path distinguished by steps carved into the rock. When you reach a chapel (8 min), leave the trail going up to the right and take the one that passes through two groups of chalets to the hamlet of Cà Burtulina (15 min) and then the church that is the nucleus of Cosasca. Pass through a group of renovated chalets to reach the shrine of Madonna delle Grucce, dating back to 1648 (6 min). Return to the Church, from where an easy mule track leads to the Church of San Lorenzo al Pozzo (31 min). From the church square, the mule track descends to the right to a chapel (6 min) and, crossing the new dirt road, proceeds to a chapel located on the old mule track that ran from Mergozzo up to the mountain passes of Ossola (10 min). Turning right will take you to the square of the church of Cosa (4 min), whilst a left turn will take you to Quarata where, in addition to the old houses, you can admire the chapel of St. Marta.
