The 17th annual ZooLights is going ape with orangutans! A larger than life lighted orangutan will greet you at the entrance while other primate light displays swing through the trees above your head! When the sun goes down and the animals go to sleep, the Phoenix Zoo transforms into one of the largest holiday lighting events in the southwest with 2.5 million lights and more than 400 light sculptures from small stars to life size giraffe, elephants and orangutans. Tickets go on sale October 1. For more information on this event please click here.
