The Chicago Botanic Garden is made up of 27 display gardens and four local habitats, which cover 385 acres over nine islands in the Cook County Forest Preserves. They include a Bonsai collection, a children's garden, an English walled garden, a fruit and vegetable garden, a waterfall garden, a model railroad garden, a sensory garden, and a rose garden, just to name a few. Note that, while admission is free, parking fees apply.
