Overview
Jackson Falls is one of the most photographed natural features in Shawnee National Forest. The waterfall drops over a curved sandstone ledge into a naturally formed grotto, and the rock walls around the pool are streaked with color from decades of mineral staining. On a clear day in spring when the falls are running full and the forest is leafing out, this is a genuinely beautiful spot.
The 1.5-mile loop that reaches the falls is short and easy, making it accessible for almost any visitor. The falls are the obvious highlight, but the dense bottomland hardwood forest on the approach sycamore, silver maple, and ironwood draped with grapevine is also notable. Rock climbers use the sandstone walls near the falls, and in summer the pool below the falls attracts waders and swimmers.
The trailhead is small, fitting only about six vehicles, which limits crowds compared to the more developed sites at Garden of the Gods. The rough forest road to the trailhead filters out casual visitors. The payoff for the effort is reliable: even the 1.5-mile distance is enough to find a quiet moment at the falls before the next group arrives.
The Route
Miles 0 to 0.6: From the forest road pull-off, the trail descends into the creek drainage through dense bottomland forest. The creek crossing near the midpoint of the approach can require rock-hopping in spring.
Miles 0.6 to 0.9: The trail reaches the falls and grotto. This is the destination spend as much time here as you like. The loop option climbs above the falls to a rim view before descending back to the approach trail.
Miles 0.9 to 1.5: The return portion of the loop follows above the drainage through drier oak-hickory forest before descending to the trailhead.
When to Visit
Spring (April through June) for maximum waterfall flow and wildflowers. Summer is popular for the swimming hole arrive early on weekends. Fall color in October is good on the ridge portion of the loop. Winter visits are possible on mild days.
Check current conditions the forest road to the trailhead can be muddy or flooded after heavy rain.
What to Bring
- A half-liter of water is enough for this short loop in mild weather. Summer heat warrants more.
- Sturdy shoes for creek crossing and rocky trail sections
- Camera: the grotto is one of the most photogenic spots in Illinois
- Towel if planning to wade or swim
- Tick repellent from April through October
