What's a Hullabuzoo? It's what you get when you bring a performing circus group, an inflatable obstacle course and a climbing wall challenge to your favorite Zoo! In between visits to our collection of endangered and rescued animals, stop into the Pachyderm Building to blow off a little steam in the free inflatable playhouse, where kids can climb, play and shoot baskets. Then gather your strength with a picnic on the Patas Lawn as you watch the performing circus group before you test your skills on the climbing wall ($3). Every time someone rings the bell at the top of the wall, we'll donate $1 to animal conservation programs. It's all about welcoming the summer with some movement... and a little mayhem.

Take an exciting journey through the San Francisco Zoo and watch the animals start their day! The Early Bird Tour is a guided tram tour throughout the Zoo where you will see and learn about some incredible animals like ostriches, gorillas, penguins, koalas, kangaroos, sea lions, bears and more. Available on weekends only, each tour starts promptly at 9:30am. Reservations are required.
