Philadelphia Zoo is adding a little green to your Halloween with the return of Boo at the Zoo! Bring your family and little ones for a day of spooky adventures:

• Put on your favorite costume and set out on a trick-or-treat safari!
• Take a walk through Philadelphia Zoo’s not-so-scary Extinction Graveyard to learn about the extinction of species around the world. You’ll be shocked to see that some of your favorite creatures could be extinct in the wild in 15 years!
• Enjoy festive fall offerings available for purchase throughout the Zoo: hot apple cider, reusable Boo at the Zoo trick-or-treat bags and much more!
• Run wild through our hay bale maze on Impala Lawn.
• Pose for a festive harvest picture in front of the giant pumpkin wall!

*Please Note: *Halloween costumes with toy guns and weapons and adult masks are prohibited.
