Boo at the Zoo


  • San Francisco Zoo Upper Great Hwy SF, CA, 94132 United States (map)

Hooray Fall

Some say that the Fall is the best time of year to visit SF Zoo with the warm late summer weather and the return of everyone’s favorite Fall activity – our giant hay maze!

Happy Hollow Hay Maze

As the largest hay structure in San Francisco, come navigate the Happy Hollow Hay Maze made up of over 600 strategically placed and stacked straw covering an expanse of 5,000 square feet. With short stacks and high stacks, kids of all ages can work to find their way through a labyrinth of bundled straw, from start to finish, and see what surprises they’ll discover along the way (hint: perhaps a hay pit?)!

Hay Maze is open now until November 4.

Boo at the Zoo

Everyone’s favorite Halloween event is back! Boo at the Zoo will take place on Saturday and Sunday, October 26 & 27 with the highlight as always, a chance to dress up in costume for the 12 noon Costume Parade and Contest as families, groups, and individuals come as their favorite super hero, animal species or the latest kids’ craze.

New this year is the Franken-stomp Dance Party which will take place after the costume party at the playground area. We hope you will all join the music and fun!

Not to miss is the return of the Haunted Nature Trail, decorated especially for the occasion with ghosts, goblins and more and the Insect Zoo will be decked out with some naturally creepy crawlers like giant cockroaches, flesh-eating beetles and giant tarantulas. Classic bug horror movies will be played on the video monitor inside the exhibit.

And the best part of the day will be the chance to see Zoo animals gobble up gourds and enjoy Halloween-themed enrichment treats at various habitats throughout the weekend – don’t forget to snap a photo of the schedule of the day’s events.
