Trees are on display through the month of December.
You will be contacted to schedule your date and time for decorating once you have reserved your tree.
Even though you’ll be near indoor areas, parts of the decorating take place outdoors—layer up to stay comfortable.
Choose natural or non-toxic ornaments to support the zoo’s conservation mission and protect local animals.
The zoo is compact but expect some walking; wear comfortable shoes for the best experience.
Mornings or weekdays tend to be less crowded, giving you more space to decorate your tree and enjoy the setting.
