The former railway line between Dannemarie and Pfetterhouse has been redesigned according to the well-known French principle as a perfect "piste cyclable" or "voie vert." Good asphalt, gentle gradients, and, above all, a lack of motorized traffic entice you to glide along at a brisk pace. Often through beautiful forests or through fields, only occasionally do you have to cross a road where there used to be a tunnel or bridge, which has unfortunately been dismantled.

Relaxing pedaling along the locks with a considerable drop.

Nice part of the climb with most of the scenic views, but also among the busiest on the street. In the last meters towards the peak, you will find an annoying accumulation of insects bothering you! Probably more lucky in fall or winter!

The Port fluvial de Dannemarie is no ordinary marina – it’s an unexpected oasis along the canal, where boats bob gently and herons keep watch. For cyclists, it feels like a little refuge: a place to take a break from the rhythm of your pedals and take on the rhythm of the water. Here you can refill your water bottle, stretch your legs on a bench in the shade or a little further away at the restaurant, or just watch the sun play on the surface of the canal.

Nice asphalted cycleway with mostly smooth surface, once in a while a few bumps created by the roots of trees below the surface. The only place where one must slow down and look where one is riding, is 1 km before Altkirch which looks to have been damaged from floods creating potholes and broken asphalt but this is the only real obstacle on this nicely well kept cycleway.

This cycling route for the most part is in very good condition, in some places a bit in need of repair from the roots of trees pushing up the asphalt, at times creating an uneven bumpy surface. The only place where one needs to pay attention is near the last 1 km before Altkrich where it seems the proximity of the cycleway to the stream has been damaged by floods, which has made the surface rough and a lot of potholes, other than that, one can really ride well on this cycleway.

Fresh public water fountains are sometimes scarce in France. A big thank you to the city officials of Hirtzbach for creating this public fountain. A perfect stop to tank up your water bottles and a lot of shade in the summertime.
