Marian R. Byrnes Park
About Marian R. Byrnes Park
Named for environmental activist Marian R. Byrnes, this 135-acre park is one of Chicago’s largest natural areas. Located in the Southeast Side’s Jeffery Manor neighborhood (where it’s known as “the prairie”), the site encompasses a variety of ecosystems, making it a great place to observe species like frogs, snakes, birds, and deer. After undergoing immense ecological restoration, the park now provides community members with a safe space to relax and connect with nature. Its new asphalt multipurpose trail runs the length of the park, giving visitors access to multiple habitats and unique views.
