The people I was staying with suggested I go to the schloss, and I'm glad they did. It was really nice. Admission was not too expensive (as a student it was only 1.5 Euros). Since I do not read German I also opted for an audio guide. It was very informative, and I learned a lot. The exhibits looked awesome. A lot of them where interactive. I think it would be enough to entertain a child. I would have gotten a lot more out of this stop if I spoke German. There were hiking trails around the castle and into the city. The view is nice.
To get the the Schloss take bus 502 from the Nuestadt train station it drops you off 200 meters from the entrance. On the way back I decided to take the trails back to the city. Be warned, the sign says 5km to the train station. It's closer to 8km.
