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.

A small entrance gives access to this fairly deep cave. It owes its name to Doctor Herrings, a village doctor with a passion for caving who died here following a landslide in 1914.

The rocks of the Grotte des Nains form an impressive gorge, approximately 25 meters high. According to legend, the little women of the earth lived here with the Erdmanala (little men of the earth). The gorge gives access to the Plateau des Nains and a beautiful view of the Ill valley.

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.
