Hocus Pocus Hall is a 4-D walk though attraction that leads throughout the mansion, with no age restriction. Theming includes animatronics such as a wizard and goblins, as well as rotating hallways and 3D paintings, for which 3-D glasses can be worn.
During the resort's halloween event - Chessington Howl'o'ween, the attraction is tuned into The Mystery of Hocus Pocus Hall, a walkthrough and maze about a missing explorer. All the theming is ripped out and replaced with scenes from around the world. The Mansion is themed to Stub Mansion, the home of the explore Sir Arthur Percival Stubbs, the resort's mascot.
