Colomby de Gex walks

Je vous propose de réaliser un parcours en boucle au départ des environs du Col de la Faucille (parking du Pailly) afin d’accéder au Colomby de Gex : à l'aller le tracé évolue sous les Monts Jura et au retour sur ses crêtes avec une succession de montées et descentes. Certaines parties du parcours sont situées en zones de quiétude de la faune sauvage et il ne sera ainsi pas possible de le parcourir du 15/12 au 15/05 (à lire ci dessous)

A superb hike, easy to follow (excellent signposting), with no particular difficulties, well worth doing for the magnificent panoramic views it offers over most of the route.

A challenging approach to a summit offering a 360° view of Lake Geneva, the Alps and the Jura. The Pas de L'Échine, a tricky and steep but very popular passage, provides direct access to the ridge in a beautiful setting. The best time to visit is in May, when it is still partially snow-covered and you have to squeeze between the snow and the rock face. However, it is strongly advised not to venture onto the nearby slopes, which are very exposed.

From the Col de la Faucille, a beautiful hike to one of the highest peaks in the Jura. Superb views of the Alps and Mont Blanc.

Only accessible from 16 May to 30 November. Subject to snow conditions. From the ridges, enjoy panoramic views of Lake Geneva and the Alps before descending into the Branveau cirque. This route on the Haute Chaîne du Jura promises an immersion in an unusual, wild and unspoilt setting. After reaching the Crozat mountain pasture, then the summit of Colomby de Gex at 1,688 metres, the descent begins via the Branveau cirque before reaching the Platières chalet. The varied and sometimes technical trail is marked with yellow markers. The Colomby de Gex pylon was originally built in Paris, then transported and erected in Gex in 1907. A memorial commemorates Fernand Fluckiger, a Swiss aviator who died in a plane crash on 2 June 1932 at this site.
