Arize Valley

Highlight (Segment) • Canyon

A nice, quiet road alongside the river Arize. A narrow canyon, a bit colder in the winter, but nice and cool during those summer hours. Very easy on passing traffic.

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.
