Infos & Booking


A natural and strategic passage between the Jura and the Alps since Roman times, the site of Fort l'Ecluse now offers a beautiful via ferrata in the heart of the Gex country.

All along this route located in the commune of Léaz in the Ain department and which connects the lower fort to the upper fort, you will enjoy a magnificent view of the Rhône and the Écluse gorge. Intermediate level, this via is accessible to most people, to spend a good time with family or friends.

After a quick approach walk, the itinerary is composed of a succession of more or less steep walls, interspersed with crossings on comfortable ledges and terraces. Two short passages slightly overhanging require a little extra effort. The atmosphere is already vertiginous and the panoramas are magnificent. The next part consists of a rocky spur which must be climbed up to the ramparts. The void is less present there but the path remains interesting.

Once the ramparts are reached, you walk along them on a vertiginous ledge before tackling the final more playful part, with the crossing of a 3 meters beam and a 15 meters cable bridge which spans the ditch of the fort and closes the course. Then you only have to walk for about 20 minutes to get back to the parking lot.

If you feel like other vertical adventures in the region, don't miss the beautiful Mont via ferrata in Sixt-Fer-à-Cheval or one of the via ferrata of Bellevaux in the Chablais.
