The Bradshaw Trail is a 70-mile graded-dirt byway across Riverside County, running from the Salton Sea east to Wiley's Well Road near Blythe and the Colorado River. The route follows the 1862 stage road that William Bradshaw scouted to haul miners between San Bernardino and the La Paz gold fields, now Ehrenberg, Arizona. The Bureau of Land Management's Palm Springs-South Coast Field Office manages it as a National Back Country Byway, and Riverside County grades the surface periodically.

Most of the route is stock-friendly two-track, but soft sand patches make 4WD the safe call. The byway parallels the northern boundary of the Chocolate Mountain Aerial Gunnery Range, an active naval bombing range, so staying on the trail is mandatory. Views span the Chuckwalla Bench and the Orocopia, Chuckwalla, and Mule Mountains.

Hazards

Read before you go

  • Adjacent military range. The byway parallels the Chocolate Mountain Aerial Gunnery Range to the south. Stay on the marked trail. The range is active and unexploded ordnance is a documented hazard if you stray off-road.
  • Soft sand. Several stretches require aired-down tires. Stock street pressure gets stuck quickly.
  • Flash floods. Summer monsoons reshape washes and can wash out the road. Check the weather and avoid the route during or after storms.
  • Heat. Temperatures top 110°F May through September. Plan a cool-season visit.
  • No services. Carry water, fuel, and recovery gear. Cell service is spotty along most of the route.

Trail Overview

The Bradshaw Trail (officially called the Bradshaw Trail National Backcountry Byway) takes adventurers on a journey through time and desert landscapes. Originally a stagecoach route established in 1862, the trail once connected San Bernardino to the gold fields of La Paz, Arizona (now Ehrenberg).

Today, it is a popular overland route that offers a remote and rugged experience with no amenities along the trail, making preparation essential.

Eagle Mountain Railroad Bridge is near the eastern end of Bradshaw Trail.

The trail's western end begins near the Wiley’s Well Campground and stretches westward for 70 miles through diverse desert terrain. Travelers will encounter soft sand patches, rocky stretches, and dramatic vistas.

Highlights include the Chuckwalla Bench and the surrounding mountain ranges. Be on the lookout for palo verde, smoke trees, and ironwood trees that dot the landscape, along with desert wildlife like bighorn sheep and roadrunners.

Due to the proximity of the Chocolate Mountain Aerial Gunnery Range, pay close attention to posted signs and avoid venturing off the trail in restricted areas. Flash floods are another potential hazard, so checking weather conditions before your trip is highly recommended.

This route particularly appeals to history enthusiasts, rock-hounds, and those seeking a challenging and remote desert adventure. Nearby attractions include the Eagle Mountain Railroad Bridge, on the western end, the Hauser Geode Beds and Opal Hill Fire Agate Mine, located just off Wiley’s Well Road.
