Top 5 Caves ダウヒンゲンでの

A beautiful, mystical place open to the public and hopefully kept clean by all visitors.

Sinkholes are funnel-shaped depressions in the ground created by the collapse of the overburden into subterranean cavities. The Waltershöhle is one such sinkhole. The shafts were formed when seepage water dissolved the limestone, creating cavities that later collapsed. Although legend has it that the Waltershöhle extends all the way to Rottweil, Walter Bürk, a Schwenningen resident after whom it is named, only managed to penetrate one and a half meters into the sinkhole opening.

Very nice and well-kept grotto. I also found the explanation very successful.

Lourdes grotto with associated pilgrimage chapel! Is close to the country road between Obereschach and Kappel. No official parking available.

Here you can see natural shafts where the underlying shell limestone was washed out by erosion.

Curious holes in the Schwenningen Forest.

An open-air service is something special.

Lourdes grotto to Elsenau. Apparently quite popular considering the number of benches. However, it was fully flooded during the last storm, since this is a grotto. But it got off relatively lightly and it was restored with a lot of personal work.
