Oooooooh, this is a question I will have trouble with because of how I a) don't remember half the places in Harry Potter b) may not be able to remember if we did a explore that place if I do find one and c) will have troubling choosing just one. One of them would definitely have to be The Burrow though. I feel as though we spent so much time in there but never really got to explore the place. There would be a ton of places to explore because it is such a cool house with probably so many cool things. I love the structure and the way it's built. It looks like a tiny house but dang the place is just so tall! Definitely want to learn more about that place.
