A range of more or less discreet fixtures ensure that the ski area, roads and people are kept safe. Among the most visible from the resort are the avalanche barriers. Set along a contour line, they are designed to hold back accumulations of snow. During your walks, you’ll probably see one or more large metal pipes. They’re part of the Gazex avalanche control system, which has the advantage of being able to secure hard-to-reach areas and can be triggered remotely.
