Henry Vilas Zoo
702 Randall Ave., Madison.
A lakeside zoo that is as famous for its scenery as the animals. It's also one of the few zoos in the nation that admits visitors free of charge. (The philanthropist who donated the land in 1904 stipulated there would never be an admission fee. Well-attended fund-raisers have kept the animals in first-class accommodations.) The zoo has a herpetarium, primate house, a Big Cat Complex for lions and tigers, and a children's zoo (summer only). The primate house is a favorite with children. Grounds are open daily 9:30 am-5 pm. Building is open daily 10 am-4 pm. Strollers, wagons and wheelchairs are available for a fee.
