Bad condition, little gravel, more stones, you (and your bike) get shaken up quite a bit. Shady though.

Beautiful, wide beach. Not exactly a highlight for road bikers, though...

From the south, a short, steep climb on mostly good asphalt. Only the last 100 meters are a bit of gravel on the road. At the top, you're rewarded with a unique view over Finisterre.

Yes, the region is known for its greenways. While the guide focuses on Cast, the broader area of Occitanie (where Castres is located, not Cast in Brittany) has invested in cycling infrastructure, including routes on former railway lines. The "Human Rights Greenway" (Chemin des Droits de l'Homme) connecting Castres to Albi is a notable example, offering a scenic and relatively flat sandy track. The Voie Verte Passa Païs, accessible from the Castres area, is another excellent option for unpaved surfaces.
