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.

Be careful, make sure you wear good shoes when it's wet. The moss can make the steps slippery. Nice in both directions 🤗
