After hours of looking at animals from afar in the rest of the Lincoln Park Zoo, kids can come here for some hands-on experience. Children are encouraged to come touch a variety of small animals -- hedgehogs, iguanas, rabbits -- under the supervision of zookeepers. There's also a very popular glass-walled animal nursery, where zoo docents and keepers care for the babies of more exotic species -- often, this means gorillas and chimpanzees -- who are ill, born weak, or rejected by their mothers. The Conservation Station has interactive exhibits and workshop activities focusing on wildlife and environmental preservation. The adjacent outdoor portion of the Children's Zoo has owls, otters, and other small critters in winding habitats sculpted from concrete.

The newly renovated Farm-in-the-Zoo is a working reproduction of a Midwestern farm, complete with a white-picket-fenced barnyard, chicken coops, and demonstrations of butter churning and weaving. Of course, you'll also spot plenty of livestock, including cows, sheep, and pigs. Inside the Main Barn (filled with interactive exhibits), the main attraction is the huge John Deere tractor that kids can climb up into and pretend to drive. (Can you say photo opportunity?) Allow 1 hour.
