Under-the-Rim Trail is located in Utah

The Under-the-Rim Trail is a 22.9-mile (36.9 km) hiking trail in Bryce Canyon National Park, Utah. The trail was established by the National Park Service to provide access to the portions of the park located below the rim of the Paunsaugunt Plateau, whose edge forms the eroded natural amphitheater for which the park is famous. Plans dating to 1932 proposed the trail so that wooded portions of the park's east side could be accessed, primarily for fire suppression activities rather than for access to scenic features. Work began on the trail in 1934, using Civilian Conservation Corps labor from CCC Camp NP-3, with work continuing into 1935.
