We followed the trail to the great Mont Rond. Then it was deserted. The weather forecast was exactly what we experienced.
We lost track of the snowshoes at the end of the descent, but that was probably due to our own carelessness. We finally found them again!

Undoubtedly the most beautiful hike of the week. A very quiet route beyond the Grand Montrond. From there, the path follows the ridge to point 9, offering extraordinary views of Lake Geneva and the Mont Blanc massif. The climb up to Colomby de Gex poses no particular problems. For the return journey, the Chalet de la Chenaillette provides a clear landmark; however, from this point back to point 5, we navigated using GPS. There were no tracks in the snow or markings. For those unfamiliar with the area, I would say a GPS is essential. Furthermore, we felt the estimated time was underestimated, despite our experience of mountain hiking, and even though we lost a lot of time with the GPS waypoints. Don’t hesitate to allow at least an extra hour.

A somewhat challenging hike due to the elevation gain, which is covered almost in one go up to the highest point of the route, and the distance involved. The route to Colomby is clear, but from there onwards, you have to navigate by sight until you reach the chalet, which is clearly visible; after that, it becomes less obvious, especially when snowshoeing: the GPS track is a useful aid.
This hike is popular as far as Grand Montrond, but much less so up to Colomby, which requires more experience to reach. The view is well worth the effort.

A wonderful hike with stunning views of the Alpine peaks and Lake Geneva.
We got a bit lost on the way back after the Chalet de la Chenillette (I’m not sure of the exact name…), but the main thing is to avoid going into the forest (stay well above it) to get back onto the path.

Hello c.oriot, and thank you for sharing your experience.

Of course, the Colomby de Gex is not the highest peak in the Jura (see the IGN map at 1:25,000). It is one of the highest peaks (correction made in the introduction).

Hello, we did a snowshoe hike, but only managed to follow the trail partway to the Chalet du Névy due to very strong winds on the ridge. It’s a lovely path (though very busy) up to the Grand Montrond, after which you have to break your own trail. There isn’t really a specific route for snowshoes: you can go wherever you like.
Incidentally, it seems that the Colomby de Gex is not the highest peak in the Jura, but the third highest according to Wikipedia:
1,720 m: Crêt de la Neige (Ain)
1,718 m: Le Reculet (Ain)
1,688 m: Colomby de Gex (Ain)
