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.

These dogs, formidable against predators such as wolves, bears and lynxes, can frighten hikers with their barking.The patou protects flocks in total autonomy. Its main role is to deter intruders and alert the shepherd. Raised among the ewes from an early age, he learns to protect them at all times, often in groups.To avoid problems with a patou:-Identify grazing areas before setting off.-Keep your distance and go around flocks if possible.-In the event of an encounter, stay calm, turn back slowly or stop to let the dog sniff you out.-Don't try to pet or feed the animals, avoid sudden movements, don't run, and avoid taking photos.For runners:-Do not run when approaching a herd.-Take off your headphones to hear the dog's barking.-By adopting these behaviors, you'll be able to cohabit serenely with guard dogs on your hikes.
