Sagawau Environmental Learning Center, in southwest Cook County near Lemont, promotes the study of nature in a relaxed setting. A visitor center and classroom building opened in 2010 includes exhibits on geology, history, and habitat management.

Some featured programs include environmental education for high schools; workshops for teachers and other adults; tours of Cook County's only canyon, and general public walks and programs. Sagawau provides habitat for over 100 species of migrant and resident birds, and is home for the banding program of the Chicagoland Bird Observatory - visitors welcome in season.

In winter Sagawau becomes a premier Nordic ski location, with rentals, lessons, and groomed trails.

Sagawau Canyon Nature Preserve is a unique area with unusual plants and rock formations. Guided walks are scheduled spring through fall.
