The One Horse Gap Trail is famous for a short loop trail known as “the gap trail”.  As its name indicates, the trail features  a narrow gap in the bluffs that allows only one horse to pass through at a time.  This trail system utilizes segments of system-trails, dirt and gravel roads and even remnants of old wagon roads.  Many interesting things can be found along the One Horse gap trail, from old cemeteries and old homesite stone foundations to towering bluffs and Bubbling creeks. The trail system provides access to One Horse Gap Lake, War Bluff and Big Grand Pierre Creek (a candidate wild & scenic river) and the River to River Trail (a 160-mile linear trail spanning southern Illinois).  Hikers and backpackers share the area with horseback riders and  hunters.  Also, be aware the Nine Day Trail Ride in late July, early August attracts thousands of Horse Riders to  the One Horse Gap Trail every year.
