Thorn Creek Woods Nature Preserve is comprised of 985 acres of oak-hickory woodland, dotted with vernal ponds and dissected by Thorn Creek and its tributary streams. Over 3 1/2 miles of trails meander through woodland, floodplain forest, scenic ravines and pine plantations. Trails lead to marshy Owl Lake and a wetland overlook. The preserve also shelters the historic Hornicek Farm, old-field habitat and a prairie sampler.

Thousands of visitors experience wildness in these woods – the centerpiece in an expanding network of open space in the south suburbs. Young and old, groups and individuals, schools and families — walk the trails, enjoy nature programs and explore the Nature Center. The Preserve influences how volunteers, children and adults think about nature. The Friends of Thorn Creek Woods make all this possible.
