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!

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

Unfortunately, the cave was completely overrun with visitors when I visited. Therefore, I recommend not visiting this place on the weekend, unless you want to enjoy the deliciously fragrant grilled food that is offered right next to the cave. The cave is surrounded by many legends and stories about meerkats and meerkat women. A visit is definitely worth it, whether to enjoy a delicious lunch or to take in the mystical surroundings.

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 ;-)

Bruderhöhle: A beautiful place, especially in summer very pleasantly cool and humid. Unfortunately you can hear the motorway, but it is still a great place
