Rock climbing
The Jackson Falls glen contains approximately 500 named climbing routes, grouped into 60 climbing areas. The climbing routes utilize the gully's bluffs and small monoliths. The erosional history of the shut-in ensures that many of the climbs are 50 to 60 feet (15–18 meters) in height. The Illinois Office of Tourism describes the locality as a site of sports routes and bouldering.
