After doing years of waiting, I've finally toured the Warner Bros. Harry Potter Studio in Leavesden, London! Here is a giant photo-dump featuring all of my favorite attractions there.
I went with my friend Henry, whom I met here at Cambridge. (How could anyone imagine going there by him/herself?) The ticket was 39 pounds. However, the transportation from Cambridge to the location itself cost around 20 pounds separately. Recently, I am feeling particularly guilty about spending money abroad, so I purchased "only" a deck of Harry Potter poker cards, a Slytherin pin, and a guidebook there as souvenirs.
Note: Some photos are exclusive contents from the tour never seen before in the films! :)
