Beautiful viewpoint "Roches de Baume" with views from the plateau into the valley and as far as Baume-les-Messieurs.

Beautiful, great, viaduct and tunnel. It's a shame the cycle path isn't asphalted.

Correction to my tip: Asphalt with mixed traffic, for residents, but I couldn't see where the residents wanted to go. It's a shame, some sections of the asphalt are no longer in such good condition.

An old railway bridge worth seeing, unfortunately there are stupid rivets on the road and it is slippery when wet.

With the many tunnels, bridges and some beautiful views, it definitely has the potential to be a beautiful railway cycle path. Most of it is not asphalted, there is light in the tunnels, but the lack of asphalt means that there are very dangerous longitudinal grooves. Later there is a staircase, which is not easy with full luggage and in bad weather. The asphalted sections unfortunately have car traffic, even if only local residents. Conclusion: unfortunately it doesn't come anywhere close to Alpe-Adria.
