In addition, there are several real locations where Harry Potter movies were filmed. Hogwarts Express going over the popular Hogwarts bridge is in real life the Glenfinnan Viaduct in Scotland. The train runs from Fort William to Mallaig. From the train you can see the Hogwarts Lake (which appeared in Harry Potter and the Prisoner of Azkaban and also in Half Blood Prince). The real location of the lake is Loch Shiel in Scotland.
