From the ridges, this hike offers a unique panorama of Lake Geneva and the Alps. The entrance to the cirque de Branveau reveals bucolic landscapes! Watch out ... the chamois are never far away!
The Colomby pylon, built in Paris and then transported to Gex, was assembled and erected for the Ain Mutualité congress held in Gex in 1907. Originally, it was topped by a cupola, and the plaque recounted the event.
