The Bundeswehr's underground facility in Neckarzimmern is a huge, complex warehouse with approximately 170,000 square meters of space and over 40 kilometers of roads and railways – originally a gypsum mine dating back to the 18th century. Today, over 190,000 items are stored there, but what exactly is in the crates remains secret.

A long staircase of irregular sandstone steps leads to this beautiful spot. At the top, you can sit in a small covered arbor, enjoy the view, and listen to the babbling brook. Many thanks to everyone who cares for and maintains this place.

The "Brasse" tunnel entrance is part of the historic "Goldfisch" underground relocation in Obrigheim, which served as an underground aircraft engine factory during World War II. The "Brasse" tunnel was a planned expansion, but only partially realized. These tunnels were built by concentration camp prisoners and forced laborers under extreme conditions.

This staircase consists of 256 slippery and varied natural steps that lead through the forest down into the Tiefenbach valley. The path is particularly challenging in wet weather as the steps can be slippery.

The mountain is completely undermined and serves as a military camp. It looks really huge. Photography and filming are prohibited. But it's really exciting.

Coming from Höchstberg, a small sign on the mountain barn shows the way from above to the grotto. From below the Untergriesheimer Weir car park, steep stairs go up.
