Hiking: Colomby de Gex from Le Pailly
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.
The route lies within the Haute Chaine du Jura National Nature Reserve. In addition, a wildlife tranquility zone is active from December 15 to May 15. As a result, the route is only accessible from May 16. Find out about the regulations before you set off.
