Compagnie des Guides de Chamonix

Compagnie des Guides de Chamonix, also known simply as Compagnie des Guides, is a historic mountain‑guide organisation based in Chamonix‑Mont‑Blanc, France. Founded in 1821, it operates as a cooperative of professional guides who provide a range of alpine services including mountaineering, ski touring, off‑piste skiing, ice climbing and high‑altitude expedition support. The organisation serves a diverse clientele that ranges from individual recreational climbers and skiers to film crews, scientific research teams and international sports teams seeking expert guidance in the Mont‑Blanc massif and the broader Alpine region. Its activities are conducted primarily in the Chamonix valley but guides are frequently deployed on peaks across Europe, the Himalayas, the Andes and other mountain ranges worldwide. The cooperative model means that the guides themselves own and govern the organisation, sharing responsibility for training, standards and business decisions.

Distinguishing attributes of Compagnie des Guides include its status as the oldest continuously operating mountain‑guide company in the world, a fact that underscores its deep expertise and long‑standing reputation in the alpine sector. Its guides are certified members of the International Federation of Mountain Guides Associations (IFMGA), reflecting adherence to rigorous international standards for competence, safety and ethics. The organisation is recognised for specialised knowledge in high‑altitude rescue, glacier navigation and weather assessment, competencies that are routinely applied both in client services and in cooperative internal training programmes. In August 2025 the organisation disclosed a cybersecurity incident in which attackers accessed confidential data such as email addresses despite existing security measures, noting that the breach could enable further malicious activity. No information about parent or subsidiary relationships is provided in the available sources, confirming that the entity remains an independent cooperative owned by its member guides.
