It's picturesquely situated and worth a visit, but a good level of fitness is required. Unfortunately, the upper access is currently closed due to a landslide (a fir tree fell and swept away the access steps directly in front of the ruins). Therefore, you have to take the longer route over the bridge further down.

Wonderful view in a very beautiful location. There are tables and buckets for a picnic. It has a special atmosphere if you go along with it. The board with explanations of the history is very clearly written.
