A fabulous place. Fortunately, it's not overcrowded, which is probably due in part to the fact that access is via narrow, sometimes steep paths. From above, you can't really see how beautiful the waterfall is. The walk is worth it!

D The 10m-deep karst cave cannot be entered without climbing equipment! The name "Tüfelschuchi" (Tüfelschuchi) derives from a phenomenon that occurs on cold winter days. When temperatures outside remain below zero, the ground remains at 8 degrees Celsius. Since the air in the crack or in the ground is warmer than outside, the warm air rises and begins to steam. People used to think this was the devil's house and his cooking! This phenomenon can be observed not only here, but in many other places on cold winter days in the Jura. 8 degrees Celsius is the annual average and constant in the Jura caves.

A magnificent place. There's water in the cave, and it's amazing how much cooler it is even at the entrance. To get there, you should have a steady footing and a fairly good head for heights.

The Bruderloch cave is a unique natural monument and, like the surrounding forest, is protected. The rocks on the edge of the Eital valley are not only impressive with their bizarre weathering forms, they are also home to the Bruderloch, one of the longest cave systems in the Basel region. Water was able to penetrate deep into the rock along cracks and, over thousands of years, chemically dissolve the limestone (= karst). This is how three caves were created in the immediate vicinity: the Bärenloch with its 30,000-year-old cave bear finds below the waterfall, the Teufelsküche in the Aleten and the Bruderloch, which is at least 300 m deep. ..... https://www.naturschutzwenslingen.ch/spezielle-orte/bruderloch-hoehle

At the Ramsflue above the sleepy hamlet of Hard, there is a small cave between high limestone towers. A beautifully laid out forest walkway leads past it. According to legend, dwarves used to hide there. Anyone who dares can enter the cave. Happy, colorful little fellows and dangerous tigers await the visitor ;-)

Very exciting cave that apparently leads several 100 meters into the rock. Don't visit alone!

A wonderful tour with many highlights that should not be underestimated. It is said that the Bruderloch cave goes several 100 meters into the rock - so please do not explore alone. A flashlight is essential. Water ingress must be expected. Entry is with an approx. 2 meter high ladder.
