Here the origin of the path can be seen: it was an old railway. The old station is well maintained.

The reconstruction is great! But we left some parts in ruins, which preserves the character of an old building.

This climb is often used by cycling races, particularly the Tour de France. A fairly long climb (2.2 km) with a very steep first section. Average gradient of 6.55% with a maximum of 15%. https://profils.cols-cyclisme.com/2811.svg

Very beautiful walk between the Abbey of Bon Repos and the lily-covered paths. Beautiful moorland landscape.
