The Wipptal is a valley extending along the Sill River southward from Innsbruck, Tyrol, Austria, where the Sill meets the larger Inn river, up to the Brenner Pass (1,374 m) at the Austro-Italian border, one of the lowest passes across the Central Eastern Alps. South of the border, it continues as Southern Wipptal along the Eisack river by way of Sterzing to Franzensfeste in South Tyrol (see Wipptal, Italy).
