The trail was first established in 1980, and was only 32 miles (51 km) long. It now runs 58 miles (93 km), mostly through public forest.
Hiking the trail in its entirety results in approximately 20,000 feet (6,100 m) of elevation change between the gains and losses. The trail passes through 3 counties and is surrounded by approximately 40,000 acres (160 km2) of Indiana State Forest. The rugged trail consists of steep climbs and descents throughout its duration. It is maintained to backcountry standards. There are no designated camp sites; rather hikers must camp at least 1-mile (1.6 km) from roads and trailheads.
After a tornado on March 2, 2012 destroyed 4.5 miles of the trail, sections of the trail were closed. The damaged areas were reopend in early 2014.
