Vernajoul Viaduct Greenway

Highlight • Cycleway

Very nice viaduct, but from here there is no view of Foix and the castle.
The interface is not good either.

The tunnels of Véloroute 81

Highlight (Segment) • Cycleway

This magnificent 44-kilometre greenway has been developed between Saint-Girons and Foix, replacing an old railway line. It has many tunnels which have the particularity of being equipped with motion detectors.

You will therefore be enlightened as you progress underground.

Col de la Crouzette (1245 m)

Highlight • Mountain Pass

Be careful, since yesterday, June 19th, the descent to Rivèrenert has been freshly graveled and dangerous. I had a rear puncture due to small, sharp gravel sticking to the tire when braking. So, don't go crazy on this descent, friends.
