Enjoy a full day at the Zoo with all the amenities with the Adventure Pass!
Animal buildings typically open beginning the first hour of operation (9-10 a.m. in off-season; 8-9 a.m. in summer). Our keepers work very hard to have animals in outdoor displays by 9 a.m. Due to husbandry concerns beyond our control, there may be times certain animals are not on display or certain animal buildings are closed to the public. You may occasionally see keepers working in an animal habitat. This is a great opportunity to ask our keepers about their work and the animals in their care!
Some of the animals are more active in the cooler hours of early morning and early evening. Occasionally, some animals may need to turn in early.
The current schedule for divers cleaning the Sea Lion Sound pools is 8 a.m. to 9:30 a.m. one day per week. That scheduled day changes weekly. The exhibit is still open when divers are in the pools, and visitors are welcome to go through the tunnel. Visitors may or may not see sea lions at these times.
Winter at the Zoo
What's there to see at the Zoo in winter? Plenty! Step inside warm climate-controlled buildings where you'll find hundreds of amazing animals and spectacular plant life. Tour tropical jungles, sandy beaches, a butterfly wonderland and much more at the Jungle of the Apes, Antelope House, Bird House, Children's Zoo, Herpetarium, Insectarium, and Primate House. Don’t forget to say hi to our frozen friends at Penguin & Puffin Coast!
For the Outdoor Enthusiast
See the winter-loving takins, grizzlies, river otters and sea lions. The Amur tigers, snow leopards, and camels have gorgeous new winter coats to show you. Ducks, geese and other waterfowl enjoy the cold months hanging out on the lakes. Visit the outdoor Antelope yards, Grizzly Ridge, Big Cat Country and Sea Lion Sound.
