Under-the-Rim Trail, Historic hiking trail in Bryce Canyon National Park, Utah.

The Under-the-Rim Trail is a hiking path that runs through the valley beneath the cliffs of Bryce Canyon, connecting different sections of the park's interior landscape. The route passes through forested areas and open terrain, with camping areas distributed along the way for backpackers.

Plans from 1932 proposed the trail to reach wooded areas on the park's east side, mainly for fire suppression rather than scenic access. Work began in 1934 using Civilian Conservation Corps labor from Camp NP-3 and continued into 1935. The trail and its branches, except the Sheep Creek Trail, were listed on the National Register of Historic Places on August 25, 1995.

The Sheep Creek Connecting Trail follows a road that existed before the park trail and was used for sheep drives. The main trail and its branches, except Sheep Creek, were listed on the National Register of Historic Places on August 25, 1995. Hikers today walk a route planned in 1932 chiefly for fire suppression access.

The route can be hiked in sections with camping areas, depending on how much distance you want to cover each day. Bring plenty of water and be prepared for elevation changes, especially over longer stretches.

The trail complex totals 32 miles (51 km) with its four connecting branches, and the Sheep Creek Connecting Trail follows a roadway that predates the park and was used for sheep drives. The main route and its branches, except Sheep Creek, were listed on the National Register of Historic Places on August 25, 1995.
