Kallektuffquel ('Lime tufa spring')

The colours of the water and rocks, as well as the variety of moss species, are truly impressive.

The best way to reach this beautiful spot is via the local hiking trail W7 (10.2 km), which starts at Heringer Millen, or via route 3 of the Mullerthal Trail. Before you reach the spring, you walk along a 600-metre-long wooden footbridge, which also runs alongside the Black Ernz and crosses it several times.
