31st Annual Boo at the Zoo

The Gladys Porter Zoo will hold its 31st annual Boo at the Zoo celebration Sunday, October 30th, and Monday, October 31st from 6 p.m. to 9 p.m. Become a Zoo member and you are eligible to come in early during the members’ only hour from 5:00 p.m. to 6:00 p.m. Come out for a ghoulishly good time at this alternative way to trick-or-treating, perfect for kids, teens and families alike!

Boo at the Zoo guests of all ages are encouraged to come out in their favorite Halloween costumes. There will be more than 50 different games and treat stations.  Concessions will have a number of snacks for you and your family to enjoy while at Boo at the Zoo! Prepare your palate for turkey legs, roasted corn, pizza, popsicles, Dippin’ Dots, nachos, and more.  Yum!


From now until October 29th, tickets are on sale online and at the Gladys Porter Zoo office for the discounted rate of $2.50 per person for non-members.  On October 30th and 31st, tickets will be $3.50 for non-members.  Boo at the Zoo is a FREE event for Zoo members with a membership card and photo ID.  Event tickets are non-refundable and will not be replaced if lost or stolen.

Zoo members have free access to the event and can get in early starting at 5 p.m. each night by showing their membership card. To alleviate congestion, there will be a total of three entrances; the main Zoo gate, a side gate in the parking lot (pre-paid admission only/members with tickets), and members needing to pick up tickets at the Membership office.

Parking will be available but is limited so be sure to arrive early or consider carpooling.
