The beaver has also settled there and built its lodge. Therefore, the southern part of the pond and the moorland areas are protected. Bathing is permitted on the north side, and a recreation zone has been set up for picnics/barbecue areas.

This section of the Sihl River is truly breathtaking. Crystal-clear water flows gracefully around massive boulders that rise majestically from the riverbed. The sound of the water cascading over the stones adds a soothing rhythm to the natural symphony of the landscape.

The Höllgrotten Baar were discovered in 1863 during the mining of tuff stone and were made more and more accessible until 1917. Thanks to an artificial connecting tunnel, you can now visit the entire grotto; a tour takes about 45 minutes. The grotto is open from April 1st to October 31st from 9 a.m. to 5 p.m. Since they are privately owned, there is an admission fee. You can find more information here: https://www.hoellgrotten.ch/.

The traces of storms from recent years and decades are clearly visible here. The Sihl does not always flow so peacefully...
