Hi all! As some of you know, I did a little holiday with a friend from uni before coming back to Durham. The first stop on our trip was London, and London is filled with all sorts of magical Harry Potter experiences, from film sites, to immersive tours, and other fun activities. So today, for all the other Harry Potter fans out there, here is the ultimate Harry Potter Holiday in London, with everything you should see and do during your stay. I hope you enjoy it!
