Hohenzollern Castle is an amazing mountaintop castle located on the mountain Hohenzollern. I visited a few years ago and filmed my experience. You can hike to the top of the mountain or take a small bus up. We hiked up, but if you have problems walking such steep inclines, then I recommend taking the bus. However, the forest and the views are incredible. You’ll see some of those views in my video. Before you arrive be sure to check the castle’s website for opening times and buy your tickets in advance.
