Everything written about the road surface and gradient of this forest lane is correct. It's unsuitable for a fast descent on a racing bike. However, it's very well suited for climbing, provided you have the fitness and leg strength, as it has a 15% gradient towards the end, just below the Col de Bonhomme. The potholes on this asphalt section are easy to avoid on the ascent. It therefore represents a genuine alternative to the D415, the Route d'Alsace, which is very busy. I advise against the D415 and recommend taking this beautiful, very quiet forest lane, the Route Joseph Valentin, where you'll encounter virtually no one – and certainly no cars. Status: July 2025

The surface isn't the best in some places, but you can still ride downhill well.

I recommend riding uphill (towards east) because the asphalt is very nasty in some places.

Plague or cholera. However, I would avoid the branch route. Poor surface and up to 20%. It's no fun

The road is quit bad at the end. First part is beautiful :)

Very pretty forest road with very little traffic, correct surface. Allows you to join the valleys of Fraize and Sainte Marie to the mines without going through the main roads.
