Since the very early days of alpine mountaineering a number of high-altitude mountain refuges have been positioned strategically across the massif to give climbers easier access to the high summits by permitting an overnight stay.
The majority are owned by national mountaineering clubs, and many are wardened during the summer months, although the smaller bivouac huts are unmanned and have very basic facilities.

Those on the most popular routes, such as the Goûter Hut, now require all climbers to pre-book.
Some tiny huts, such as the remote Eccles Hut, can also be extremely crowded during good mountaineering weather, and some climbers prefer to bivouac outside.
