About This Trail

One Horse Gap is a forest preserve managed by the United States Forest Service, located in the Shawnee National Forest outside Herod, Illinois. It contains a short loop trail named "the gap trail," a narrow section in the bluffs that is only wide enough for one horse to pass through at a time. The trail provides access to Big Grand Pierre Creek, One Horse Gap Lake, War Bluff, and the River to River Trail.
