While the prosperous times in the town of Lucelle are over, the Lac de Lucelle is a nature reserve that captivates with its peace, idyll and beauty. The lake can be easily walked around on a well-developed nature trail, and there are many benches where you can watch the ducks and fish in the lake.

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.

At this point / I would like to quickly / say something about the source And specifically to quote the incomparable humorist Heinz Erhardt (1909 - 1979), who was known to a wide audience for his wit and "Another poem", with a short four-line line: "There is certainly a lot of beauty in the element, the wet. Because you can drink the water. But you can also - not." (H.Erhardt)

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.
