The Wechsel is part of the Prealps East of the Mur. It is – apart from the Vienna Woods which are half the height – the easternmost range in the Alps. Its highest point, at , is the Hochwechsel, formerly called the Hoher Umschuss, at the top of which is the Wetterkoglerhaus, an Alpine Club hut belonging to the Austrian Alpine Club. From there the crest of the mountains runs northwest to the Umschußriegel ( ,) continuing to the Schöberlriegel ( ), and east to the Niederwechsel ( ).
The Wechsel is the boundary between the Styrian Joglland and the Bucklige Welt, which stretches from the Vienna Basin to the extreme southeast of Lower Austria. To the east this region transitions into the Pinka valley, the Güns Mountains and the Pannonian Plain.
Important settlements at the foot of the Wechsel, which benefit from tourism associated with the mountain, are Aspang, Aspangberg-St. Peter, Dechantskirchen, Feistritz am Wechsel, Friedberg, Kirchberg am Wechsel, Mönichkirchen, Mönichwald, Pinggau, Trattenbach, Sankt Corona am Wechsel, Sankt Jakob im Walde, Sankt Lorenzen am Wechsel, Vorau, Waldbach and Wenigzell.
