Steinerne Rinne bei Wolfsbronn, Protected limestone formation in Wolfsbronn, Germany.
The Steinerne Rinne near Wolfsbronn is a natural limestone tufa channel located in the municipality of Meinheim in Middle Franconia, Germany. It was formed by calcium-rich spring water that slowly deposited mineral layers over time, building up a raised rocky streambed.
The tufa channel formed through a natural process that has been going on for centuries and is still active today. The site was placed under protected status in 1984 to safeguard this ongoing geological process.
The name "Steinerne Rinne" means "stone channel" in German, which describes exactly what you see when you arrive: a narrow rocky gutter still carrying water. Mosses and liverworts cover the wet surfaces along the stream, creating a soft green layer over the pale limestone.
A wooden walkway leads from the parking area on county road WUG 34 straight to the formation, making the path easy to walk even when the ground is wet. Information boards along the way explain the geology and ecology of the site, so even a short visit covers a lot.
The channel is not a fossil relic but is still actively growing, as the mineral-rich water continuously deposits new rock along its bed. This makes it one of the few places in Germany where you can watch rock formation happening in real time.
