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

A path often in the shade, 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.

Amazing camping which was open but quiet when I visited in early May 2025 (tip - many French campings don't open until later in May). I would give this 10/10 even with the slight disturbance of the tranquilité caused by the construction of an enormous zip wire across the lake. The camping is located a long way from 'civilisation', at least by bike. However.... it has such great facilities, like a decently stocked and not expensive épicerie, incredibly clean loos and showers, decent self-catering (including amazing Office de Randonneur - an actual indoor kitchen which hikers and bikers are free to use. All this and a private (ish) viewpoint over the lake. Oh and a depot du pain and café service in the morning. Pretty much perfect
