The 525-acre McKinley Woods was acquired between 1931 and 2004.
McKinley Woods has two access areas, both in Channahon: Frederick's Grove and Kerry Sheridan Grove.
The preserve is part of the Des Plaines River preservation system, which conserves more than 2,400 acres. Prior to the District's acquisition of the land, it was a private resort and was commonly called "Moose Island." The Frederick's Grove Shelter is a remnant of a Civilian Conservation Corps camp that was built on the site.
McKinley Woods protects a diversity of habitats, including forest, prairie, wetland and a portion of the Des Plaines River.
Wildlife found at the preserve includes the queen snake and 99 bird species, such as the cedar waxwing, bald eagle and purple martin.
The preserve is also home to a variety of plant species, including redbud, blue ash and chinquapin oak.
The site is managed with invasive species control, prescribed burning and habitat restoration to protect and enhance its natural resources.
