Naturbadesee Lichtenberg, Natural swimming lake in Fischbachtal, Germany

Naturbadesee Lichtenberg is a natural swimming lake in Fischbachtal with clear water and undeveloped shorelines. The water body features varying depth zones and is fed by a stream that naturally maintains its water quality.

The water body originated from an earlier quarry that was converted into a bathing destination in the 1920s. This transformation of an industrial site into a recreational area has shaped the location's history.

The lake has been used for swimming since 1926, and the campsite on its southern shore dates from 1953. The name Odenwaldidyll is also used for the site, and the stream feeding it is the Bach vom Eselsbrunnen, which rises from several springs.

The lake lies on the northern edge of Lichtenberg and is reached via a turnoff from the L 3102 through the Fischbachtal. A campsite runs down to the southern shore, so bathers share the bank with campers. The water is shallow and fed by the Bach vom Eselsbrunnen.

The water is fed by the spring source of the Eselsbrunnen stream, keeping it pure without chemical treatment. This natural water circulation sets this lake apart from many modern swimming facilities.
