Wonderful view of the stunning viaduct du Viaur, an engineering marvel, taking the railway across the gorge of the Viaur. Designed by Bodin, not Eiffel as is commonly misunderstood, it is an amazing sight. There are picnic benches to sit and admire it

The Pont de Thuriès is a 13th Century bridge over the Viaur river that opened up trade between the Rouergue and the Albigeois regions. There is a picnic area nearby and you can also swim in the river.

Nice climb with some tight switchbacks, partly in the trees but also offering some views of the valley and river below.

Medieval bridge with six arches over the Viaur. A little swim and a drink at the bistro des 3 hiboux, right next door, recommended!

After the hike, first take a dip in the Viaur below the bridge, then a fresh craft beer at "Les Trois Hiboux". A dream!

While the trails themselves are generally open to responsible dog owners, it's important to consider the difficulty of the routes. The 'difficult' rating and significant elevation changes mean these trails might be strenuous for some dogs.
