Tickets go on sale October 1 for Boo at the Zoo, the event will kick-off October 16 and run through the 30th. You can purchase your tickets at stlzoo.org/boo. Tickets are fairly priced so that everyone can attend. Zoo members are $7.95 (ages 2-12); $8.95 (13+), non-members: $8.95 (ages 2-12); $9.95 (13+), and children under 2 are free. You must buy your tickets online, as there will be no tickets sold at the gate entrance.

There will be a few time options when buying tickets on when you can enter the event. The staggered times are 5 pm to 6:30 p.m. and 6:30 to 8 p.m. (event ends at 8:30 p.m. Last admittance is at 8 p.m.). You are asked to arrive at your reserved time slot, and once you enter you can stay as long as you want.

Participates are encouraged to wear family-friendly Halloween costumes (costume masks are not permitted for any age), and make sure you bring your camera. There will be plenty of opportunities to take pictures in front of ghosts, pumpkins, Frankenstein or mummies.
