This extremely cool, wild gorge leads through the 2020 landslide area (rehabilitated) and continues along numerous footbridges along the rocks and the stream. At the back, the path continues only via rather steep steps. The path is not suitable for dogs due to the many gratings.

A wonderful piece of nature, highly recommended. If you like deep gorges dug by water, this is the place for you. The path is very well developed with bridges and footbridges, making it easy to walk. However, there are only two exits at the north end via steep stairs, so you should take this into account.
