Very beautiful, well-appointed cave where you can eat together

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.

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

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 Bruderhöhle can be found on maps from 1840. There are many stories and legends surrounding the karst cave. The cave was renovated by the municipality of Effingen in 2017 and is now freely accessible again. There are several nice barbecue areas here, in front of the cave or above the stairs.

During the Second World War, this tower was used as an air observation post. The forest grew higher and higher, making it necessary to expand the tower. In 1953, it was increased by 6 meters and in 1987 by a further 9.5 meters.

rather amusing. The Solothurn begins 200m further on, where the path climbs again sharply.
