오웬‬에서 가장 멋진 ‪20‬개의 천연기념물

Teck Castle sits enthroned at an altitude of 773 meters on the Albtrauf of the Swabian Alb. The Swabian Alb Association runs a restaurant and a hostel here - the ideal place to take a relaxing break with a great view during your tour.

Walter Röhm, author of the Bad Urach hiking book, explains how the hell holes came about so - actually they are cracks in the rocks of the Weißjura delta lying on top in this area of the Alb - so that the underlying marl layers of the Weißjura gamma are to be regarded as impermeable to water. As a result, water that has penetrated into the upper layers, hitting the marl, must come out and flow down the slope and cannot seep away. During this process, according to Röhm, the layers of marl soften and become slippery, so that they no longer offer proper support to the rocks above. This process continues until individual clods tear out and go to the valley. The dizzyingly narrow rocks lying down the valley – if not already hanging – are floes that are doomed to fall but have not yet gone down into the valley, and which have already become detached from the Alb body as a result of the process described above. It will be difficult to predict when they will follow other crash candidates that have preceded them.

Imposing castle ruins, easy to reach. Nice as a destination for a hike.

An absolute highlight. Be sure to walk through it and use the two short steel ladders. The canyon is very impressive!

Here you should already know where to put your feet ;) Two ladders and a rocky climb out of the hell hole... It can be very slippery there and as an unsafe occasional hiker you should think twice. At least not go alone. But when you do it, it's an unforgettable experience. The history of the earth is presented very intensively right here. We were very impressed down there ;)

From this ledge you have the most direct view of the Reußenstein ruins. In winter you have to be careful not to slip on the snow-covered rocks.

Very impressive - you should definitely see it for yourself 👍🏻

On hot days, the hell holes offer a good cool down. The descent or ascent is worthwhile. The premium hiking trail Hochgehflogen leads past here.
