Schwarzach Bridge Canal

In the 19th and 20th centuries, the Ludwig-Danube-Main Canal (also known as the Ludwig Canal or "Old Canal" in the region) was a 172.4 km long waterway between the Danube near Kelheim and the Main near Bamberg. In a broader sense, the canal, built between 1836 and 1846, was part of a navigable connection between the North Sea near Rotterdam and the Black Sea near Constanța. By crossing the European main watershed, the ambitious construction project took on a special position. 100 locks, some in the Altmühl and Regnitz rivers, managed a total difference in altitude of 264 meters (80 m ascent from the Danube and 184 m descent to the Main). Between Beilngries and Nuremberg, the Ludwig-Danube-Main Canal has largely been preserved in its historical scope and with some functions.

The Ludwig-Main-Danube Canal crosses the Schwarzachtal by means of a bridge and is therefore one of the special architectural achievements of the already impressive canal. Originally there were 10 such canal bridges, of which only 3 have survived.

Long flat path to the right and left of the canal with many old locks and lock keeper houses, some of which are now gardening. You can run endlessly here, because of the straight gravel paths it can be tiring or boring. But you can also find many rest stops on the way.
