It is 23 kilometres long and runs gently downhill along the Eckbach river through the Leiningerland in the northeast of the Palatinate region.

It links nine villages and 23 of the original 35 water mills, running from the Palatinate Forest through the vineyards along the German Wine Road to the edge of the Upper Rhine Plain.

The route, which is accessible all year round, is marked by wooden signposts, made and maintained by voluntary workers.

The logo depicts a house and waterwheel above a wavy line and was designed by Cosmas Kösters from Kirchheim in a school competition.

On 12 October 1997 it was inaugurated by the minister president of Rhineland-Palatinate, Kurt Beck, in Großkarlbach, the village with the most surviving mills (six of seven).
