The Paria River (pron.: //) is a tributary of the Colorado River, approximately 95 miles (153 km) long, in southern Utah and northern Arizona in the United States. It drains a rugged and arid region northwest of the Colorado, flowing through roadless slot canyons along part of its course.
It is formed in southern Utah, in southwestern Garfield County from several creeks that descend from the edge of the Paunsaugunt Plateau, meeting just north of Tropic. It flows SSE across Kane County and Grand Staircase-Escalante National Monument. Along the Arizona state line, it descends through the Vermilion Cliffs in the Paria Canyon and onto the Paria Plateau. It joins the Colorado from the northwest approximately 5 mi (8 km) southwest of Page, Arizona and the Glen Canyon Dam. The lower 20 mi (32 km) of the river are within the Paria Canyon-Vermilion Cliffs Wilderness, which is administered by the Bureau of Land Management; a permit is required for any overnight visit. The Paria is essentially a large creek and is not navigable.
The Paria is one of the most popular destinations for canyoneering in the region. Buckskin Gulch, a side canyon along the river in the narrows section, is considered to be one of the longest and deepest slot canyons in the United States. The Paria is also home to a number of important historical, geological and biological resources. Lee's Ferry and the adjoining settlement are located within the canyon just upstream of the confluence with the Colorado River, with a number of other abandoned settlements further north. The Paria and several nearby rivers and canyons also are the site of several well-preserved specimens of Native American petroglyphs, prehistoric drawings and symbols carved into stone. The Paria boasts a vibrant desert riparian habitat that is home to a number of sensitive and endangered species, and is also the location of Wrather Arch, the longest natural arch outside of Utah (although this claim may be superseded by Aloba Arch).
About a mile south of the river and the ghost town of Pahreah is the Paria Movie Set which was the site for a number of western movies. Among the movies filmed at this site and the surrounding area were The Outlaw Josey Wales (1976), Sergeants 3 (1962), Westward the Women (1951), and Buffalo Bill (1944). The old film set in the canyon was a popular attraction but was damaged in a flash flood in 1998. The buildings were dismantled and rebuilt in a nearby location by volunteers. In 2006 these new buildings were destroyed in a suspicious fire.
