Endowed by Colonel William Vilas in the early part of the 20th century, this 28-acre zoo is unusual for not charging admission fees (a feature also dictated by Vilas' bequest). Exhibits are easily managed in a few hours time, and include such animal mainstays as giraffes, primates, lions, camels, and tigers. You'll also find a reptile house, children's zoo (where little ones can feed the animals), penguin exhibit, and more. Food services and a gift shop are available as well.
