Described above is the upper waterfall, the "Rünenberger Gießen", where the water falls over a curved rock face 18 m into the depths, forming a stately tufa pyramid below, with the jet atomizing roaring and foaming depending on the water level. In winter, fascinating icicle formations are created at sub-zero temperatures. Above the waterfall is the "Löligumpi", where you could swim in the past. A little further down follows the Kleine Giessen - also with a beautiful tuff cone.

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

Ideal if you can visit the waterfall during the week. There are very nice fire pits.

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

Since the Wiesenberg is in the forest, this observation tower makes sense. It takes hikers above the treetops and allows a 360-degree panorama. There are panorama boards. The climb is worth it.

The Bruderloch is an almost 300 meter long cave system and is protected. Various rooms can be discovered in the entrance area; a ladder leads up to the main hallway.

Sense is pretty fast down in the water, you can still squeeze through a few passages at the top, but be careful!
