Bronnbach

The Bronnbach spring is a high-yield karst spring in the Oberes Gäu near Rottenburg am Neckar, managed by the town of Rottenburg. Karst springs of this scale form where groundwater filters through porous limestone and resurfaces in a concentrated flow — a geologically notable occurrence in the region. The site offers a quiet stop for hikers and anyone interested in local hydrology, with little in the way of developed tourist infrastructure.
