Underground river course

The underground river is a beautiful natural spectacle. It consists of a river of stones. It is also said that the Steinerne Mühl got its name from the underground course of the river.
Unfortunately, there is no hiking trail leading directly past this beautiful place. It can be reached via the V10 "Große Waldkapellenrunde" to Güterweg Hofau, where it joins the "Sterngartl Rundweg" (only a short stretch), then along the underpass under the main road.
