I went there last year! It’s absolutely gorgeous and totally worth the trip. We signed up for a private tour with a driver from Innsbruck and she was fantastic. Before our scheduled tour time, she walked us around the grounds, showed us some off-trail lookout points and we got amazing photos from it. It’s definitely worth spending a day there, and plan on walking around the town after seeing the castle, and leave time to check out one of the local restaurants for pretzels or brats and beer.
