Visit the Zoo!

The Zoo is free and open daily from 8 a.m. to 4 p.m. Entry passes are required for all guests, including infants.


During peak visitation days at the Zoo, you may be greeted upon entry by one of the security personnel who will conduct a thorough but speedy hand-check of all bags, strollers, briefcases, purses and containers. You may also be hand-screened with an electronic wand. Because of the security measures, the lines for entry to the Zoo may be longer than usual during peak seasons and holidays. We ask for your patience, cooperation and assistance in keeping everyone safe.
