The Birkensee

The Birkensee is a local recreation area within the town of Röthenbach
in the Nuremberger Land district.
It consists of the Großer and Kleiner Birkensee lakes.
The lakes are located approximately 13 km east of Nuremberg
in the Lorenzer Reichswald forest, near the Nuremberg motorway junction
and are part of the Franconian Sand Axis.
Both bodies of water are fed by the groundwater
of the Röthenbach stream, which, separated by a sand dune,
flows past to the northeast and flows into the Pegnitz River in Röthenbach.
