National Parks in Illinois.

By Nicholas Major · Last updated

Illinois has more than five NPS units, anchored by Lincoln Home National Historic Site in Springfield and Pullman National Historical Park in Chicago. Lincoln Home is the only home Abraham Lincoln ever owned. Pullman preserves the planned company town built around the Pullman railcar works, a landmark of American labor history. Other units include trail segments of the Lewis and Clark, Trail of Tears, Mormon Pioneer, and Underground Railroad routes. Chicago O'Hare (ORD) and Midway (MDW) anchor the northern state; Springfield (SPI) is closest to Lincoln Home; St. Louis (STL, Missouri) reaches the southern trail segments. Lincoln Home tours are free year-round but need a same-day ticket from the visitor center. Arrive early in summer.

Methodology

Rows come from our combined NPS metadata and Visitor Use Statistics registry, not the Park Service's official census of 433 managed system units. Per-record visit counts come from the official NPS Visitor Use Statistics Data Package, 2025; the "5-year average visits" column is the mean of 2021-2025 Recreation Visits. Multi-state records are listed under every state they touch, and their full visit total appears in each state. Official National Park counts use the central 63-park classification rather than the source designation label alone. Independent site, not affiliated with the National Park Service.
