Every avid Harry Potter fan knows where Platform 9 ¾ hides in King’s Cross Station. Once you’ve found the magical wall, grab your cart and push your way through. Hogwarts Express awaits. For more fun, a new Harry Potter gift shop was opened right by the platform. So stop in to find drawers full of magical wizarding gear. London itself is full of filming locations from the films. Now there is even a Warner Bros Studio Tour that takes you through the making of Harry Potter.
