The sandstone cave in the Schwarzachklamm got its name from the Swedish king Gustav Adolf, who is said to have attended a sermon given by the Nuremberg pastor Cornelius Mareius there in 1632 after a battle victory in the Thirty Years' War. It is the largest of the erosive washes in the Schwarzach Gorge. https://urlaub.nuernberger-land.de/detail/id=6220ae58f24f424775ea02b6

The waterfall now consists of a small trickle in summer, at most to wash your hands.

Visiting the large rock cellar is really fun. Already at the entrance you feel a coolness. A flashlight is a must, just to get around the wet, greasy spots on the floor.

In fact, everything has already been said here. The hiking trail between the Schwarzach and Karlshöhle is unparalleled. But not on the weekend.

The cave together with the Schwarzach is a highlight in the area. Avoid walking on Sundays and public holidays. It starts with the parking lot.

The small river Schwarzach has cut deep into the Burgsandstein between the Schwarzenbruck district of Gsteinach and the bridge canal of the Ludwig-Danube-Main Canal. The middle castle sandstone was formed about 215 million years ago during the Mesozoic (Triassic). This type of rock is widespread in western and southern Middle Franconia[6]. Hard and resistant rock like the Burgsandstein narrows a valley to a gorge. The erosive power of the river could only cut into the rock along fissures and faults. The hard sandstone types form the steep gorge walls. Less hard rock layers such as clay layers and weak zones led to the riparian areas being undermined, especially during high water. This resulted in scours, overhanging roofs and surf caves. The two largest caves of this type are the Karl's Cave and the Gustav Adolf Cave. Source: Wikipedia
