The upper section of the valley is called Wildgerlostal. The Gerlos pass (alt. 1,509 m) connects Tirol and the Salzach valley (upper Pinzgau valley). Gerlos, the main village, lies at 1,245 m above sea level; the Gerlosbach stream is impounded in the Durlassboden reservoir, close to the Gerlos pass.
