The water that disappears into the Höllenloch largely reappears after 5 days (dye tests) in the Enzbrunnen in the Ruiter Tal.
Further sinkholes are hidden in the forest east of the federal highway.

Great path from Seehauspfad to Seehaus

The only way to the unguarded cave entrance, located in the middle of a forest, is via a rather overgrown path. The connection from the Enzberg Oak, marked as a forest road, is very difficult to follow and only vaguely recognizable as a path. Nevertheless, the somewhat adventurous route there is worthwhile.

The first difficulty is getting to the cave 🤷‍♂️ Dense blackberry vines and hawthorn make access via the marked paths impossible 😅. You have to somehow 👀 make your way across the 🌳forest 🤷‍♂️ Once you get there, the largest cave in the Enzkreis is quite inconspicuous; you can't see much because the entrance leads directly down a vertical shaft, so you can't see much. Descending is definitely to be avoided without equipment and experience ☝️. But just being here and even finding it is a bit of an adventure 👍.

Super "mining region" with some mine entrances, ventilation shafts, tunnels and! Trails 👍😀 Maybe "a bit extreme advice" on the Käfersteige tunnels! https://vnv-urbex.de/altbergbau/deutschland/fluss-schwerspatbergbau/flussspatgrube-krabbelkaefer-kaefersteige/
