The Schneeberg, with its 2076 m-high summit Klosterwappen, is the highest mountain of Lower Austria, and the easternmost 2000 m-high mountain in the Alps. It is a distinctive limestone massif with steep slopes on three sides.
The Schneeberg is one of the Northern Calcareous Alps in the borderland between Lower Austria and Styria, in the eastern part of Austria. It and the Rax (2007 m), some 13 km to the south-west, are collectively considered the Viennese Hausberge (local mountains). The rich Karst plateaux have provided drinking water for Vienna, via a 120 km-long pipeline, since 1873, claiming to be the best drinking water in the world.
