It seems a bit silly to be posting about a holiday event in January, but the ideas could be used tfor a generic Harry Potter Party Year Round.
Horcrux scavenger hunt in the library. I saw the idea on Pinterest. I gave them a list of the items to find and told them to think out of the box. I only gave them clues when they got stuck.
I had 2 craft options, but we ended up running out of time. The crafts were a Whomping Willow paper sculpture and an origami Christmas tree.
I had several photo ops set up around the room: Eeylops Owl Emporium, Platform 9 3/4, and a Christmas tree.
Weasleys' Wizard Wheezes, and a Magical Creature Hunt.
