The Sasso Gordona is a 1,410-metre mountain that closes the Val d’Intelvi to the south, on the border with Switzerland: modest in height but slender in profile, it offers a 360-degree view and one of the most complete visits to the remains of the Cadorna Line.
History
The defensive system that in Lombardy and Piedmont is called the “Cadorna Line” (its official name is Occupazione Avanzata Frontiera Nord) was built between 1911 and 1916 to stop a possible attack from Germany through Swiss territory: hundreds of kilometres of cart roads, tunnels and positions along the western Prealps, dug by thousands of men in difficult conditions. It was never used in war, because not a shot was ever fired from the line; in the following decades its roads instead served mountain communities. On the slopes of the Gordona you meet trenches dug into the rock, walkable tunnels, shelters and positions for machine guns or light cannon, along the Sentiero Storico Linea Cadorna, where a few panels explain the fortifications. The mountain’s name, according to Wikipedia, comes from the Celtic gur, “sharp”, and dun, “summit”: “sharp mountain”.
What to see
The rock is Moltrasio limestone, and the summit, with a steel cross about four metres high dating from the 1930s, can be recognised from much of the plain. From the Prabello hut (1,210 m), at the foot of the mountain, you can choose: climb to the top, or follow the southern circuit, a path that passes among the fortifications and rejoins the main route near Monte Fontanella. The hut is a refreshment point on the walk and a good viewpoint over the Val d’Intelvi. From the summit the eye ranges over Lake Como, Switzerland and the whole Alpine arc.
Getting there
By car you climb from Argegno towards San Fedele and Lanzo, then through Erbonne and Casasco, to a narrow road that leads to Pian dell’Alpe: the last three kilometres call for experience of mountain roads. From the car park you walk about half an hour to the end of the road and climb a pasture towards the east, then follow the wood along the Italian-Swiss border to a very visible boundary stone; the Prabello hut is reached in about fifty minutes from the car. Beyond the hut you climb the west shoulder: after some huts the path becomes more demanding, with a rock step passed using hands or a chain, then the first First World War tunnels and a second shoulder fitted with chains, and finally the ridge line with the cross. The climbing stretch takes about 1 hour 40 and 450 metres of ascent; the Region’s Rifugi di Lombardia portal rates the route Escursionistico EE (for experienced hikers). With snow or in autumn crampons are needed. You descend eastwards with a short chain-aided ridge, following a trench to the mule track that comes from the Bisbino and then, with the signs for Pian dell’Alpe and the Alta Via dei Monti Lariani, in about half an hour you are back at the hut. Times, difficulty and trail conditions change with the season and should be checked before setting out (CAI, hut managers, weather forecast).
Practical information
- Height: 1,410 metres (OpenStreetMap, Wikidata, Wikipedia). Wikipedia and the hiking guides place the summit in the municipality of Schignano; according to OpenStreetMap it falls in Cerano d’Intelvi, where the Prabello hut also stands: the top is close to the boundary between the two.
- The Prabello hut is on the route of the Via dei Monti Lariani; Wikipedia notes that the route passes under the mountain’s north side.
