As Erlengraben it is diverted from the Alb. In Rüppurr it is called Hertelgrabe, in Karlsruhe then Petergraben. After it has passed under the main railway line, it is returned to the Alb.

The old harbor was an important transshipment point for Rhine shipping in the 19th century. When the Karlsruhe Rhine harbor began operations in 1901, the harbor lost importance and the transshipment of goods came to a standstill. Today, it is a popular and very idyllic recreational area on the edge of the Rhine meadows.

Beautiful nature reserve. The many white willows and dragonflies are immediately noticeable. Softwood and hardwood floodplains together form the floodplain forest, the species-richest habitat in Central Europe. Up to 400 day and night butterflies and over 900 different beetle species can be found here, including some species that are endangered throughout Europe.

Large gravel pit lake in the middle of the Rhine floodplains. The name is reminiscent of historical smuggling in the Rhine region. Popular with anglers and paddlers. Many boats on the shore are a picturesque eye-catcher. Definitely worth a detour from the dike path.
