Mountaineering and excess visitation

The Col du Mont Lachat is located on the standard route for the ascent to Mont Blanc, the highest peak in Western Europe.
This mountaineering route requires special equipment. Between 15,000 and 20,000 people attempt it every year. This large number of visitors is bound to have an impact on this fragile environment: disturbance of wildlife, trampling, and anti-social behaviour (littering, etc.).
