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.

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.

These caves constitute a fascinating network of caves and cavities. You can visit the Truchet, Creux aux bêtes, Silberloch and Lucelle caves, which reveal the geological history of the region. These caves are a great place for photography!

Additionally, the Alt-Biederthal Castle Ruins area features a castle rock cave, and the Schlossfels Cave is a small tunnel within the castle rock.

The difficulty varies. The Dwarves' Grotto involves a gorge and access to a plateau. The Castle Trail, which includes cave sections, is described as narrow and potentially exposed, requiring caution. The Alt-Biederthal Castle Ruins, with its rocky outcrop and cave, can be climbed with a little skill. Always check specific route details for the latest conditions.
