The Wasenhorn (German, Italian: Punta Terrarossa; 3,246 metres (10,650 ft)) is a mountain of the Lepontine Alps , located on the border between Switzerland and Italy. It lies halfway between Brig (Swiss canton of Valais ) and Varzo (Italian region of Piedmont ), just north of Monte Leone , in the Simplon Pass area. Politically the Wasenhorn is split between the municipalities of Ried-Brig and Varzo.

The Simplon Tunnel runs into the massif of the Wasenhorn, below the subsidiary summit named Tunnelspitz (2,903 m (9,524 ft)).

Just follow to the road towards the Simplon pass, either from Brig on the Swiss side, or from Domodossola on the Italian side.

The normal route to the summit of the Wasenhorn starts from the Monte Leone Hut of the Swiss Alpine Club (2,848 m (9,344 ft)), located on the south side of the mountain, above the Chaltwasser Pass, which connects the Simplon Pass with the Alpe Veglia.
