The Main-Donau-Kanal summit monument, near Pierheim at KM 102.2, marks the divide between the watersheds of the Rhine/North Sea and the Danube/Black Sea. The route joins the Altmuhl river valley, following it down to the junction with the Donau at Kelheim. The summit elevation is 406 metres (1,332 ft) above sea level, the highest point on Earth that is currently reached by commercial watercraft from the sea.
Thousands of photos taken on two trips down the Danube (first trip starting at Calais, France and the second trip from Vlissingen, Netherlands, both all the way to the Black Sea) have been used to create the EuroCanals PhotoNav Guides for the Danube. They include the photos shown on this website.
In full-page format they display the details of landmarks along the route, in a km-by-km sequence. The photos are identified by kilometer post; they include ports, bridges, locks as well as sites worth noting. Examples are described on this page:
