Founded to realize the vision of Edith Rockefeller McCormick (1872-1932) for a cage-less zoo in Chicagoland, the Chicago Zoological Society operates the Brookfield Zoo on land that belongs to the Forest Preserves of Cook County (formerly the Forest Preserve District of Cook County). Essentially, the C.Z.S. has the same kind of relationship with the Forest Preserves of Cook County that the Chicago Academy of Sciences, the Chicago Historical Society, The Field Museum of Natural History, the John G. Shedd Aquarium, the Museum of Science and Industry, the Adler Planetarium & Astronomy Museum, and the Lincoln Park Zoological Society have with the Chicago Park District. Chicago Tribune editorial cartoonist John T. McCutcheon (1870-1949) served as the first President of the Chicago Zoological Society from 1921 to 1948. Architect Edwin Clark (1878-1967), who also designed two homes for Mister and Mistress James Ward Thorne, a library in a third home, and the first twelve Thorne Miniature Rooms, designed the original buildings for Brookfield Zoo in the early 1920s and early ‘30s. The Brookfield Zoo is accredited by the American Zoological Association.
The North Gate Main Entrance stands at the intersection of 31st Street, west of 1st Avenue and the Des Plaines River. It is east of Salt Creek. The address of the North Gate Main Entrance is 8400 31st Street, Brookfield, Illinois 60513.
The South Gate Main Entrance parking lot is adjacent to Riverside Brookfield High School. The Regional Transportation Authority (R.T.A.) has two different public transit methods that service Brookfield Zoo at the South Gate Main Entrance. It is a four-block-long walk north from the Hollywood Station on Metra’s B.N.S.F. Railway line, which connects Chicago to Aurora. Consequently, in good weather, families will ride the train and get off at the Hollywood stop to walk to the zoo. That train station is also labeled the “Zoo Stop.” Walk north for two blocks along Hollywood Boulevard. Then turn right to walk east for one block along Washington Avenue. Next, turn left to walk along Golf Road. Two Pace bus routes also have stops outside the South Gate Main Entrance: Route 304 and Route 331. The address of the South Gate Main Entrance is 3300 Golf Road, Brookfield, Illinois 60513.
