The Via Ferrata Aletsch runs along the rock around the Gibidum reservoir. It is secured by iron rungs, wire cables, and railings but still features some fairly demanding sections. These are especially found on the eastern shore. At the steep rock walls of Stockflüe, you really have to get a grip, as there are some exposed and slightly outward-leaning traverses.
A special thrill is the 80 m long and 40 m high Nepal bridge, which crosses the Massa river at its mouth into the Gibidum reservoir.
