The "source of the acidic water" can be visited from a small jetty. The elements of iron, sulphur, calcium, magnesium, sodium and potassium have formed a so-called spring pot over time.
A landscape like from Mars. Everything red, red. This spring near the footbridge is rather closed, you have to go down. There are tiny springs and a creek that flows and forms tiny terraces on a strip 10 to 30 meters wide.
