Presentation
The road and its 17 hairpins (protected area) leading from Pontamafrey to Montvernier, via the beautiful chapel of La Balme, has made the site famous.

Seen from the huge granite cliff, it is simply breathtaking.

The route
From the Sertours parking site, follows the blazed trail westward to join the road, and go up the left bank of the stream (15 mn).

The via ferrata climbs up a vertical slab on the left of the footbridge.

An airy, but easy, traverse leads to a second cliff and an overhang (two ladders). There is the footbridge, 30 meters long over the waterfall and an impressive chasm.

A few easy descending ledges and a few steeper passages lead back to the car (footpath).

Access
From RN 6, take D 77 and drive into Pontamafrey. Then turn left towards Montvernier and right at the Sertours parking site. There is a "via ferrata" signpost at the foot of the cliff.

Other activities
Rock climbing nearby.

Presentation
A lot more demanding, steep and airy, the Bastion is a sequel to the Passerelle.

Impressive overhangs add to the beauty of the cliff, before discovering the charm of the Montvernier plateau... and maybe the terrace of its friendly inn.

The route
At the end of the descent from the Passerelle via, the Bastion footpath is signposted. After an easy traverse and the first cables, the route gets very steep and even overhanging on a 40-meter section.

Already tired your arms now attack an overhanging ridge of the same length. Keep your arms extended and rest your weight on your feet !

You can stop on a small platform before starting on the third vertical section, still overhanging !

Enjoy the well-deserved charm of the plateau before descending the 17 hairpins of the Montvernier road.
