The Tour is located 20 miles from Central London at Warner Bros. Studios, Leavesden, where the Harry Potter movies were filmed. Tickets won't be available for sale at the attraction, they must be booked online through the official website.
When you go into the tour, a cinema shows you clips of why the Philosophers Stone became a film. The film will end with Ron, Harry and Hermione going into the Great Hall. The screen will lift up, revealing the actual Great Hall. Then you go into a room including props from the Yule Ball, wigs and costumes. Across from it there is a large caldron and Malfoy Manner, the Potions classroom, containing Snape and Slughorns outfits and The Griffindor common room. Then you can see cars and motorbikes, and from there you may go broomstick flying and appear to be flying in a Ford Anglia. Then there is the Ministry and Ministry-run aspects, such as the Daily Prophet, next to the Weasley house and the Death Eaters. Outside there is Privet Drive, the Knight bus, Butterbeer, the Potter Cottage, and the Hogwarts Bridge. Then you go into the model studio, with Dobby, Aragog, Griphook and more. You then go into Diagon Alley, preceeded by sketch rooms. Down a corridor, there is a large model of Hogwarts used for exterior shots within railings, so you go down the ramp and see it all. You are then in a small room like Olivanders. Each box has on it the name of a person even vaguely involved in Harry Potter, with a man there to lend you his wand so you can have a photo of you pointing to your faviorate. You then led to the gift shop, where you can by anything from Extendable Ears and Pygmy Puffs to the Weighing of The Wands set and Hermiones Yule Ball Gown, as well as a vast selection from Honeydukes, the Hogwarts clothing shop which seems to have opened, and wands from most characters from Harry to Narcissa.
