A historic and symbolic structure representing industrial development and trade in the Jura, the Moulin des Pierres bridge is also a remarkable natural site that can be admired from the 40-meter high bridge or from the belvedere close by. Here, the Valserine has carved deep gorges in which tenacious plants have overtaken the rocky sides underlining the valley. The bridge’s daring construction offers a unique view over the Pont des Pierres Natural Regional Reserve. 

From the Pont des Pierres parking lot, cross over the bridge to reach the trail bordered by fences on the other side of the D 14A. After a short 250 metre ascent, cross the road again and descend 50 metres to a stony path on your right which will lead you to an adapted bevedere. Return the same way.
During this hike, you will come across three interpretive signs:

  • The Moulin des Pierres bridge: its history, details about its construction and old photos.
  • The Pont des Pierres gallery: presentation of the Pont des Pierres Natural Regional Reserve and its species.
  • Geological view of the Gorges of the Valserine: geomorphological explanations on the origin of this landscape.
