One of Illinois’ most beloved outdoor destinations is getting a major refresh, and improvements continue as we begin to emerge from hibernation and start to head outdoors. Starved Rock State Park, the state’s most visited park, is undergoing an $18 million trail improvement project designed to make hiking safer and help preserve the landscape for years to come.

Located about 100 miles southwest of Chicago, Starved Rock is home to towering sandstone bluffs rising above the Illinois River and forested trails winding through canyons carved by glacial meltwater more than 14,000 years ago. Established in 1911 as Illinois’ second state park, the site is known for its 18 dramatic canyons, seasonal waterfalls and sweeping river views.

The park’s popularity has taken a toll on its infrastructure, however. Over time, heavy foot traffic and harsh Midwest weather have worn down many of the timber bridges, stairways, boardwalks and retaining walls that guide visitors through the rugged terrain. To address that, the Illinois Department of Natural Resources launched a large-scale trail rehabilitation effort in late 2025 that will continue through most of 2026.

The goal is to repair aging structures, reopen previously closed trails and make the park safer and easier to explore.

Construction is being staggered so that only certain areas are closed at a time. Currently, several routes are temporarily off limits while crews work, including the Brown Bluff Trail above French Canyon, Tonti Canyon and Tonti Bridge, the west side trail between LaSalle Canyon and Tonti Canyon and the trail leading from the west entrance to the boat ramp area. The Lone Tree Canyon staircase and the Owl Canyon overlook have also seen closures during portions of the project.

Short-term closures are also happening for tree removal and maintenance work. Work continues, and as of February 24, 2026, the IDNR says that trails may close temporarily through mid-March, with conditions changing day to day. Visitors can still access much of the trail system, and the historic Starved Rock Lodge remains open throughout construction.

If you’re planning a trip, park officials recommend stopping by the visitor center for the latest trail updates before heading out. Staff and volunteers can suggest alternate routes so you can still experience the park’s sandstone canyons, waterfalls and wooded overlooks.
