Somewhat difficult paths to walk, but the view is worth the effort! The descent through the bar's terrace was particularly interesting.

Although now only a few ruins remain of what once was, a castle once stood here. There is now an area with picnic tables, ideal for stopping for lunch. If you get here by one of the trails that arrive, a little before you will also pass by a small pond.
