Roughly 25,000 years ago, where the Wisconsin Glacier reached its furthest point south and stopped, the creation of Great Swamp began. With cattail marshes, wet meadows, swamp woodlands, and ridges thick with oak, beech, and laurel, Great Swamp provides a home for 39 species of mammals including mice, moles, skunks, raccoons, otters, foxes, white-tailed deer, and the endangered Indiana bat. Migratory birds see Great Swamp as a "nest and rest" (244 species have been identified). Numerous reptiles and amphibians have taken up residence, including rare bog turtles, wood turtles, and blue-spotted salamanders.
The Great Swamp National Wildlife Refuge was established in 1960 following grassroots action to save the area from being developed into a major metropolitan airport. In 1968, the eastern half of the Refuge was designated as the very first Wilderness Area within the Department of the Interior. About 8.5 miles of primitive trails provide access during daylight hours only, and camping and picnicking are not permitted.

Digital and paper maps are critical tools for wilderness visitors. Online maps can help you plan and prepare for your visit ahead of time. You can also carry digital maps with you on your GPS unit or other handheld GPS device. Having a paper map with you in the backcountry, as well as solid orienteering skills, however, ensures that you can still route-find in the event that your electronic device fails.
Motorized equipment and equipment used for mechanical transport is generally prohibited in all wilderness areas.
This includes the use of motor vehicles, motorboats, motorized equipment, bicycles, hang gliders, wagons, carts, portage wheels, and the landing of aircraft including helicopters.
