The cave can be reached from Biedertal Castle by taking the narrow path between the two castle buildings. The cave itself exudes a special atmosphere. It didn't invite me to linger ;-)

I could no longer see any ruins on this overgrown rock. The narrow path, which seems to be taken from a fairy tale book, leads to Biedertal Castle, but is always worth a visit. Once you arrive at the castle grounds, it is not immediately clear where the path continues. If you want to visit the castle rock cave, the narrow path leads through the buildings and down into the forest. The cave itself exudes a very special atmosphere.

Only a few remains of the castle walls remain, but the rocky outcrop is impressive and can be climbed with a little skill. Most of the stones were then used for the nearby Biederthal Castle.

A small cave or rather a tunnel that is in the castle rock. This must be stepped through or hiked over for the ascent / descent.
