The route starts in Porto Ceresio and follows the border trail to the hamlet of Cà del Monte. Just above the village, a characteristic wayside shrine marks the point where the route continues across the border into Switzerland.

After passing through the locality of Serpiano, the trail begins to gain elevation until reaching Sant'Umberto, in the Cassina area. From here, the final uphill section leads to the summit of Monte San Giorgio.

A hike on Monte Orsa allows you to appreciate a natural view with numerous glimpses of Lake Lugano, as well as numerous witnesses of the famous Cadorna Line. Monte Orsa offers unforgettable and extremely interesting trekking : starting from the town of Viggiù, at a certain point the roadway becomes a path and on a bend we find a yellow sign indicating the ascent on foot to Monte Orsa (about 45 minutes).

For history, war, and hiking enthusiasts, this route offers the possibility to see practically intact military works of the Cadorna line, breathtaking views and hardwood forests . The well-marked route starts from the town of Viggiù (461m/1512 feet), where you can follow the tourist signs of the Cadorna line. Proceed towards the Colle Sant’Elena and continue until you meet the Monte Pravello’s signs. After the votive chapel it’s possible to park at the beginning of the Sentiero degli alpini.
