About Cedar Falls
Cedar Falls tumbles roughly 80 feet into a narrow sandstone canyon tucked within Shawnee National Forest, making it one of Illinois’ taller and more dramatic cascades. The falls are especially striking after periods of heavy rain, framed by steep rock and mixed hardwoods that make the runout below the drop a scenic spot for photos and a short rest. While multiple places share the name “Cedar Falls,” this entry refers to the waterfall reached from the forest trail in southern Illinois. The waterfall is reached by a relatively short, moderately rated hike: an out-and-back route of about 1.7 miles with roughly 200 feet of elevation change. The approach winds through forest and descends into the canyon, so expect rocky, uneven footing in places. The nearest developed camping is at the Hidden Springs Ranger District, approximately 17.4 km (about 10.8 miles) away, so overnight options are not immediately adjacent to the trailhead; plan accordingly.
The Setting
Cedar Falls sits at 436 feet along the South Fork Saline River, in the coastal lowlands of Illinois. The falls drop 80 feet.
Height: 80 feet
