Visitor Tips

  • 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. Monday, Wednesday and Friday each week. That schedule is subject to change. 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.

  • The Living World and North Entrance will be available for visitors regardless of temperature as long as the Zoo is open. The Zoo is open daily year-round except Christmas Day and New Year's Day.

    Oct. 31 through Feb. 24, 2016

    Cafe Kudu, the restaurant at The Living World, will be open only on weekends (weather permitting). Lakeside Cafe will be available every day the Zoo is open. The Chef's Daily Special will continue to be offered at the Lakeside Cafe.
