In honor of the 50th anniversary of the opening of the Children’s Zoo, admission to the Children’s Zoo on Saturday, May 18 will be just 50 cents per person for ages 2 and up; children under age 2 are free.

On June 14, 1969, the first Children’s Zoo opened at the Saint Louis Zoo. It was the vision of Marlin Perkins, who served as zoo director from 1962 to 1970, and other zoo leaders, to connect children to animals through contact in a space that offered a sense of adventure.

Admission to the Emerson Children’s Zoo is free from 9 to 10 a.m. in spring; 8 to 9 a.m. in summer, starting May 24. Vist stlzoo.org for more details.
