How to get there
Cadiz Dunes Wilderness lies 40 miles east of Twenty Nine Palms, between State Highway 62 and historic Route 66 in San Bernardino County. The north-side parking area is reached by an access road that can be sandy; four-wheel drive may be necessary. Obtain maps and confirm the road approach with the BLM Needles Field Office, 1303 S. Highway 95, Needles, CA 92363; 760-326-7000. Do not use the interior wilderness map point as a driving destination.
- North-side dunes parking area
The identified parking area is on the north side of the dunes. Its access road can be sandy, and four-wheel drive may be necessary. Confirm the approach with the BLM before traveling.
- State Highway 62
A regional approach corridor south of the wilderness, not an identified trailhead or direct wilderness entrance. Use an area map and BLM guidance to establish the connecting road approach to the north-side parking area.

Dunes and creosote in the Cadiz Valley
Cadiz Dunes Wilderness protects 19,935 acres in San Bernardino County, California, including most of the Cadiz Dunes and some surrounding land. Designated in 1994, it is managed by the Bureau of Land Management and lies within Mojave Trails National Monument, north of Joshua Tree National Park. The dunes sit in the Cadiz Valley between the Calumet Mountains and the Old Woman Mountains. North winds built them by carrying sand off Cadiz Dry Lake; creosote dominates the land around the sand. The appeal here is the dune landscape and the opportunity for solitude, rather than a prescribed itinerary. Plan a self-directed visit, with a map and a clear return plan, and distinguish the wilderness boundary from the roads used to reach it.
Seasons, plants, and desert wildlife
Early spring, late fall, and winter offer the more moderate conditions for exploring Cadiz Dunes, with temperatures generally ranging from 30 to 80 degrees Fahrenheit. That range still calls for layers and attention to the forecast. Summer temperatures commonly exceed 115 degrees and can rise well above 120 degrees; avoid treating a summer walk as a routine outing. Carry water whenever visiting the dunes and choose an outing that fits the conditions. Spring can bring a display of dune plants, including Borrego milkvetch, listed by the California Native Plant Society as rare and endangered in California. Give plants room rather than walking through them for a closer look. Wildlife includes coyotes, black-tailed jackrabbits, kangaroo rats, quail, roadrunners, lizards, and rattlesnakes. Watch where hands and feet go, and observe animals without approaching or feeding them.
Access planning and wilderness travel
The approach deserves as much planning as the walk. The access road to the parking area on the north side of the dunes can be sandy, and four-wheel drive may be necessary. Obtain an area map from the BLM Needles Field Office and confirm the approach before committing to unfamiliar roads. A mapped point inside the wilderness is not a trailhead, campsite, or vehicle access point. Within designated wilderness, motorized equipment and mechanical transport are generally prohibited, including motor vehicles, OHVs, and bicycles. Contact the BLM to confirm current access conditions, applicable regulations, and any permit requirements. Follow desert-appropriate Leave No Trace practices: travel and camp on durable surfaces, pack out waste, leave natural objects in place, minimize campfire impacts, and give wildlife and other visitors space.

Route options
- Cadiz Dunes
Plan a self-directed walk into the dune landscape from the north-side parking area. This is an exploration option rather than a named, marked trail. Set the turnaround according to temperature, water supply, and the effort of walking on sand; avoid trampling dune plants.
- Creosote lands surrounding Cadiz Dunes
Explore the creosote-dominated land surrounding the dunes as an alternative to concentrating on the sand. This is a self-directed terrain option, not an established route. Use a wilderness map to stay oriented and within the intended area, favor durable surfaces, and give wildlife space.
Sample itineraries
- Cool-Weather Dune Walk · 1 day
Use the north-side parking area for an on-foot visit to the Cadiz Dunes. Choose your turnaround based on temperature, water and energy rather than a fixed mileage. Confirm road conditions before driving in; sandy access may require 4WD.
- Spring Plants and Desert Wildlife · 1 day
Plan a slow spring visit to observe dune plants, including Borrego milkvetch, and the creosote-dominated surroundings. Watch quietly for roadrunners, quail and lizards. Avoid trampling vegetation, leave flowers untouched and carry water throughout the walk.
