Clear Springs Wilderness

Clear Springs Wilderness, located on the west side of Shawnee National Forest, is one of the largest designated Wilderness areas in Illinois. Elevations range from 400 to over 900 feet, featuring rugged terrain with narrow ridgetops, steep slopes, and scenic creeks winding through the valleys. Adjacent to Bald Knob Wilderness to the south and the LaRue-Pine Hills/Otter Pond Research Natural Area to the west, Clear Springs is also defined by the waters of Hutchins Creek, which flows through the area. At the western boundary, you’ll find stunning views of the Mississippi and Big Muddy Rivers from sheer limestone bluffs that rise 400 feet above the valley floor.
