October 17-30, 2017, nightly 5:30pm - 8:30pm

Power up! Video game characters, superheroes, butterfly princesses, lil' furry monsters, cuddly lion cubs, ticklish tigers, pirates, cowboys and ballerinas with their mummies and daddies are about to invade the Saint Louis Zoo for Boo at the Zoo Nights!


  • $6 for Zoo members (ages 2+)
  • $7 for non-members (ages 2+)
  • Free for children under 2
  • $1 discount for children 2 to 12 in costume with on-site ticket purchase


This non-scary, kid-friendly Halloween experience is filled with laughs and adventure. Children are encouraged to wear costumes. Children 12-and-under will receive a treat bag upon exiting. Boo at the Zoo Nights is not a trick-or-treating experience.

Because Boo at the Zoo is a family-friendly event with young children who might be frightened, visitors age 13 and over in costume are not allowed unless they are accompanying children. Specifically, zoo policy requires no adults can be wearing a mask or otherwise have their face covered with face-painting, etc.
