These three trails were the first designated National Scenic Trails in the National Trails System.[4] Their total length is about 7,875 miles (12,674 km); vertical gain is more than 1,000,000 feet (300,000 m). A total of 22 states are visited if the three trails are completed.[5] The American Long Distance Hiking Association – West (ALDHA–West) is the only organization that recognizes this hiking feat. At the ALDHA–West gathering, held each fall, the Triple Crown honorees are recognized and awarded plaques noting their achievement. As of the end of the application period in 2023, 665 hikers have been designated Triple Crowners by ALDHA-West since 1994.[6]
