  • Be spellbound by fabulous decorations throughout the Zoo, including Skeleton Soiree, Monster Mash, Flutter Forest, Pirate Pointe and Halloween Town.
  • See strolling entertainers and stage shows.
  • Take a rollicking ride on the Zooline Railroad and go for a spin on the Conservation Carousel.
  • Savor special fall-themed menu items, available for purchase.
  • Jump-start your holiday shopping with a visit to our open gift shops.

Candy Shopping Guide

Orangutans, bears and other animals are in danger due to unsustainable palm oil plantations, which destroy their forest homes. Palm oil can be found in many products — even Halloween candy. Use this shopping guide to find candy that uses sustainable palm oil.
