Platform 9¾

Must see for any Harry Potter fan in London. If you're with a local, they can navigate the station easy enough. If not, simply ask anyone walking in or out (that's not in a hurry) and they'll point you to it. There's usually a line but it moves fast. They provide you with wands and your House scarf, too! It's free to take pictures and group shots, and a professional photographer snaps your picture too. You can purchase a print out for 9 pounds in the shop beside it, along with loads of HP merch. This is not the time to be shy or feel embarrassed; let your nerd flag fly!
