Unlike mountain huts, these are unattended shelters. It is therefore necessary to bring food and minimum equipment, leave the spaces in order and clean and comply with the indications in the bivouac.
Usually they are open, but in some cases it may be necessary to obtain the keys in advance.

N.B. Some bivouacs can be reached by hiking trips of various difficulty while others can be reached by following mountaineering routes.
