Had the pleasure of riding this route last week and well worth the effort. D431 is not well signposted in Cernay and we had difficulty finding the right road. Lots of hairpins and climbing and busy at weekends with a right mix of bikers, Sunday afternoon drivers, cyclists and walkers - bit like the Peak District except more mountainous. Agree with the comment earlier - a few corners are cobbled and I imagine this would be nasty in the wet. Still, the views are stunning, the road surface, in the main is good, and Id recommend this as a great biking experience.
