The first road across Riverside County to the Colorado River was blazed by William Bradshaw in 1862 as an overland stage route. Beginning in San Bernardino, the trail was used extensively between 1862 and 1877 to haul miners and other passengers to the gold fields at La Paz, Arizona (now Ehrenberg). The Bradshaw Trail is a 70-mile dirt road, periodically graded by the Riverside County Transportation Department. Four-wheel-drive vehicles are recommended due to stretches of soft sand. The trail traverses mostly public land, and offers spectacular views of the Chuckwalla Bench and the Orocopia, Chuckwalla and Mule Mountains. The Bradshaw Trail National Backcountry Byway is administered by BLM's Palm Springs-South Coast Field Office.
