The treasure at Kallenberg Lake

**Start/End: Neckargemünd; exact meeting point provided upon registration** Passing the "Hollmuth" protected forest, we look back at the Neckar loop from the hilltop.

Via Neidenstein, we reach Eschelbronn and the local nature reserve "Kallenberg." A nature tour takes place with a view of the former quarry site.
