The Rhine-Nahe-Eck is often the final point of our MTB tours in the home country and if the large staircase is free, she is also happy to be surfaced (shut down). Not to forget the great view of the Rhine, the mouse tower, and the Germania.
Since the Landesgartenschu took place there a few years ago, the Rhine bank in Bingen is really beautiful. There is also a great playground right by the mouth of the river. Highly recommended for families with children.
