This is the longest tunnel on the greenway: it's super fun to go through. Be careful: it's a bit chilly!

Due to the challenging nature of the terrain, with demanding elevation profiles and difficult grades, most gravel bike routes in Sor are not recommended for families with young children or those seeking very easy rides. The region caters more to experienced riders looking for a significant challenge.

Given the challenging routes and varied terrain, it's advisable to pack essentials such as plenty of water, energy snacks, a repair kit (including spare tubes, pump, and multi-tool), appropriate layers of clothing for changing mountain weather, and a first-aid kit. A GPS device or a loaded komoot tour on your phone is also highly recommended for navigation.

Are there any less crowded gravel biking options in Sor?

While Sor is known for its network of unpaved roads, the region's challenging nature means it generally attracts experienced riders rather than large crowds. To find quieter routes, consider exploring some of the less-trafficked paths that venture deeper into the forested areas, such as the Saint-Lary – Portet-d'Aspet pass loop from Castillon-en-Couserans, which offers a remote feel.

Can I find cafes or refreshment stops along the gravel trails in Sor?
