Nierstein-Mainz-Bingen

Predominantly asphalt, although partially very poor in the Mainz metropolitan area. The urban area of Mainz experiences heavy traffic, but there is a separate bike path. The signage for the Rhine path within the town is very inadequate, especially around the harbor. From Mainz towards Bingen, there are sections of gravel with significant potholes. However, from Ingelheim, the path improves again.
