The Solsteinhaus is an Alpine Club hut belonging to the Austrian Alpine Club located at a height of 1,806 m (AA) on the Erl Saddle (Erlsattel) between the mountains of the Nordkette and Erlspitze Group.

Due to its central location and the numerous tour options it offers, the hut is a base for climbers taking part in tours of several days long, as well as a starting point for summit attempts.

During safe avalanche conditions, high Alpine ski tours can be undertaken to the surrounding summits; but these all require good experience.

In the evening hours of 7 June 2006 a brown bear, JJ1, otherwise known as Bruno, was seen from the Solsteinhaus.

On the following day several 15 to 20 centimetre large imprints of bear paws were found near the building.
