Located above Méaudre village, Le Trou qui souffle is accessible all year round by heading for the ski slopes on the old Autrans road. One kilometre further on, take the first road left for 500 m. At the edge of the path, two cracks in the rock exhale a glacial wind which comes from the depths of the earth. In fact, this hole is part of a huge network of galleries and shafts left behind by the water in which air circulates over several kilometres.
