Alpine Club hut

Alpine club huts (German: Alpenvereinshütten) or simply club huts (Clubhütten) form the majority of the over 1,300 mountain huts in the Alps and are maintained by branches, or sections, of the various Alpine clubs. Although the usual English translation of Hütte is "hut", most of them are substantial buildings designed to accommodate and feed significant numbers of hikers and climbers and to withstand harsh high alpine conditions for decades.

They provide hikers and climbers with accommodation and shelter, mainly in the Alpine region. The greater number of these huts are managed, several are only suitable for those able to be self-contained. Although fundamentally all those involved in mountain activities have access to the huts, preferential service is given to members of the Alpine clubs. These include: reduced accommodation rates, mountaineer's meals, hot water for tea, the right to provide one's own food and alcohol-free drink (sometimes for a nominal fee). For unmanaged huts members can obtain a master key (alpine club key, Universalschlüssel or AV-Schlüssel) for a deposit from the local alpine branch. Sleeping accommodation may consist of beds, a mattress room (Matratzenlager) and emergency beds or shakedowns.

The larger alpine clubs in Europe have a multilateral agreement to treat members of other clubs as their own members at their club's huts (reciprocal rights). These clubs include: the German and Austrian Alpine Clubs, the Club Alpin Français, the Club Alpino Italiano, the Swiss Alpine Club and the Federación Española de Montanismo as well as several smaller clubs.
