Good hairpins running up the hill to Viel Armand (A french war memorial cemetary on the top of a mountain), although there are about 3 hairpins which change to cobblestone surface rather oddly (could be very dangerous in the wet). The descent can be a bit tricky because of paint on road and bumps so be careful
The Western section close to Munster is fairly ordinary, the best part is the rise up into the mountains to the Col de la Schluct. If you're heading into France from Southern Germany, this is one of the best ways to do it! It also links nicely to another route, Gerardmer to La Bresse over the Ballon d'Alsace.
Fast flowing route with good surface through forest reserve area, beware of some tourist car parks and wood on road from tree felling
