“Mountain wilderness” refers to any pristine, untouched mountain environment, where anyone can experience vast open spaces, silence, solitude, nature. “The value of wilderness therefore lies above all in its potential to stimulate a creative relationship between civilised man and the natural environment. It is the degree of authenticity of this relationship that gives a non-ephemeral meaning to adventure.”

This definition dates back to 1987, when the Biella theses, our manifesto, were written. They marked the birth of Mountain Wilderness.

Mountain Wilderness International (MWI) is the umbrella organisation of the national chapters of Mountain Wilderness. It facilitates communication and exchange among national chapters, coordinates and organises international projects and actions and officially represents the organisation in its relations with governments, authorities, international institutions and non-governmental organisations.

If you share our ideas and you wish to help us, please join a national chapter. Mountain Wilderness has chapters in a dozen countries.
