The Via Ferrata Aletsch climbing route runs along the rock face around the Gibidum reservoir. It is secured with iron rungs, steel cables, and railings, yet it still features some quite challenging sections—especially along the eastern shore. On the steep rock walls of the Stockflüe, climbers need to use their hands and strength, as there are some exposed and slightly overhanging traverses.
A particular thrill is the 80-meter-long and 40-meter-high Nepal bridge, which spans the Massa River at its confluence with the Gibidum reservoir.
