Wilderness hut

A wilderness hut, bothy, backcountry hut, or backcountry shelter is a free, primitive mountain hut for temporary accommodation, usually located in wilderness areas, national parks and along backpacking and hiking routes. They are found in many parts of the world, such as Finland, Sweden, Norway, northern Russia, the Alps, the Pyrenees, Scotland, Australia, New Zealand, Canada, and the United States. Huts are basic and unmanned, without running water.
