Good spot for taking a break or escaping a sudden storm! There's some places to sit, as well as an overhanging roof where you can hide from the rain :)

There's so many great views around the lake, and this is one of them! On a clear day, you can see very far in the distance. But even with less-than-perfect weather, there's still a lot of natural beauty to enjoy.

The view from Ruggisberg is breathtaking: on one side the glittering Lake Constance stretches out, on the other the imposing peaks of the Alpstein rise into the sky. The landscape seems almost magical, especially at sunrise or sunset.
