Better known as The Making of Harry Potter, this is a walk through the actual film sets, props and costumes at Warner Bros.’ Leavesden studios near Watford, where the films were made. Diagon Alley, the Great Hall and the Hogwarts Express are all part of it. It opened in 2012, and you need to pre-book a timed ticket. Kings Langley station is a little over 2km to the north-west.
