Großer Brombachsee near Enderndorf

In the summer months, a trimaran, which is unique in Europe with its architecture and construction, travels on the Great Brombachsee between the Ramsberg, Absberg, Enderndorf, Allmannsdorf and Pleinfeld piers.
A trimaran is a boat or ship with three narrow hulls arranged parallel to one another at a greater or lesser distance. The middle hull is the largest, the two lateral ones serve to ensure tipping stability. Source: Wikipedia

The large Brombachsse, together with the small Brombachsee and the Igelsbachsee, forms the Brombachsee, which was inaugurated in 2000 and is the largest reservoir in the Franconian Lake District. The lake is one of the largest dams in Germany in terms of both area and storage volume. In addition to flood protection in the Altmühl valley, it is primarily used to regulate water for the rain-poor northern Bavaria.

Always worth a visit. Worthwhile road bike destination, as it is in a varied area. No "big" mountains, but a few steep hills.
