Chicago Portage National Historic Site

The Chicago Portage National Historic Site is a National Historic Site commemorating the importance of the Chicago Portage in Lyons, Cook County, Illinois, United States. It is located in Chicago Portage Forest Preserve and the Ottawa Trail Woods Forest Preserve, at the junction of Portage Creek with the Des Plaines River, on the west side of Harlem Avenue on the line of 48th Street. Preserved within the park is the western end of the historic portage linking the Chicago River to the Des Plaines River, thereby linking the Great Lakes to the Mississippi River.

A memorial depicting the portage of French explorers is located at the parking area. A trail leads from the memorial down into the portage wilderness area. The site commemorates the Chicago Portage, first written about by French explorers Father Marquette and Louis Joliet during their use of the portage and exploration of the area between Lake Michigan and the Mississippi River.

The portage crossed what was known as Mud Lake, which could be wet, swampy, frozen, or dry, depending on the season, and which has since been obliterated. Mud Lake extended roughly from the historic western end of the South Branch of the Chicago River (near today's Damen Avenue) to the Des Plaines River at the present National Historic Site.

Chicago Portage National Historic Site occupies a particular place in the imagination of American public lands. As a National Historic Site in Illinois and Michigan and Mississippi, it represents a deliberate choice — by the people who advocated for its protection, and by the National Park Service rangers who maintain it — to keep this landscape available to anyone willing to make the trip. That accessibility is the quiet miracle of the park system.

The pages linked below break the visit down into the four practical questions every traveler asks: where can I hike, where can I sleep, what else is worth seeing while I'm in the area, and what should I know before I show up. Each one is written from the perspective of someone planning their first trip — assume nothing, explain what's worth explaining, and skip the marketing language. If you've been here before, treat these guides as a refresher and a way to discover the corners you missed last time.
