Route description This unusual via ferrata was built by Saas Valley mountain guides but lies on Italian (Piedmont) soil, linking Rifugio Andolla with the Almagellerhütte as part of a two-day crossing from Gondo to the Saas Valley. Despite its name, no lake is found near the route itself; it references the distant Lago Maggiore, visible from the Sonnigpass on clear days. The via ferrata is only a moderately difficult highlight within a much larger alpine journey through the wild, little-visited Zwischbergental and Almageller valley. Good weather, solid mountain experience, and up-to-date route conditions matter more here than raw climbing strength.

From Zwischbergen, follow the trail over the Passo d'Andolla to Rifugio Andolla (4-5 hrs). From there, a well-marked path gains height steadily through the Alpi di Andolla; at a junction (2458 m) keep right toward the Bivacco Varese, ascending stony meadow slopes to the start of the Mittelrücken east ridge and the always-open bivouac. From Bivacco Varese, follow a faint trail steeply up to the start of the via ferrata (approx. 2880 m, about 2½ hrs from Rifugio Andolla).

The route begins easily over slabs and grassy ledges before steepening into well-secured sections. Climbing is engaging and height is gained quickly, aided by iron rungs and bars where natural holds are lacking. A dramatic series of ladders leads up the final wall to the Sonnigpass at 3147 m, marking the top of the ferrata.

From the exit, descend the gently sloping western snowfield into rocky terrain, where white-blue-white markers guide the way across block- and scree-covered ground beneath the Portjengrat, with a few short counter-ascents, down to the Almagellerhütte. From there, follow the hut trail past the Almagelleralp to Saas Almagell (about 2½ hrs).
