Get ready for an unforgettable evening of mystery and excitement at Philadelphia Zoo! The third annual “Zoo Done It?," in partnership with Without a Cue Productions, will be held on Saturday, August 1, 2026 from 5:30-8:30pm. New for this year, guests 16+ are welcome to this after-hours scavenger hunt and mystery experience that gives them the chance to uncover the secrets hidden within the Zoo’s enchanting grounds as they embark on a special quest. Guests are encouraged to dress up in their best 1920’s apparel (with comfortable shoes, of course!).  Participants will try to solve the mystery with one winning an exclusive chance to return to the Zoo for spooky season and enjoy a private guided tour of The Solitude, a famous American historic landmark which is believed to be haunted.
