Mojave Trails National Monument
Spanning an incredible 1.6-million acres, and created by Presidential Proclamation on February 12, 2016, Mojave Trails National Monument connects to Joshua Tree National Park along its southern border and Mojave National Preserve on its northern border in California’s Mojave Desert region.
Located a short 30-minute drive east from 29 Palms and comprised of more than 350,000-acres of previously Congressionally designated Wilderness in the California desert, Mojave Trails is home to a stunning mosaic of rugged mountain ranges, ancient lava flows, and spectacular sand dunes. The monument protects irreplaceable historic resources including ancient Native American trading routes, World War II-era training camps, and the longest remaining undeveloped stretch of Route 66. Additionally, the area has been a focus of study and research for decades, including geological research and ecological studies on the effects of climate change and land management practices on ecological communities and wildlife.
While visiting 29 Palms, we encourage you to plan some time to go out and discover this vast and beautiful part of the California desert region. Whether you’re interested in hiking and stargazing, keen to find some new OHV routes, looking to go rockhounding or wildlife viewing, or intrigued to explore historic sites and scenic geology, Mojave Trails offers an exciting diversity of outdoor recreation opportunities, all within a short drive from 29 Palms.
Through a unique partnership with the Bureau of Land Management, the City of 29 Palms was established as an official Gateway Community to Mojave Trails National Monument in 2018. Visitors will find a great variety of resources, maps, and information about Mojave Trails at the 29 Palms Visitor Center, located at the corner of Hwy 62 and Desert Queen Ave in downtown 29 Palms.
Mojave Trails National Monument Adventure Itineraries
Amboy Crater National Natural Landmark is a 10,000-year-old volcano and adjacent lava flows, located next to the original and iconic Route 66. Recognized for its visual and geological significance, Amboy Crater was first established as a National Natural Landmark in 1973 and is one of Mojave Trails’ most popular sites, offering a unique opportunity to experience and explore one of the youngest volcanic fields in the U.S. Day use area includes shade ramadas, picnic tables, vault toilet restrooms, paved road and parking lot, interpretive kiosk and scenic observation point. Due to the extreme heat the basaltic rock reflects, hiking to Amboy Crater is recommended only in the late fall through the early spring season.
Cadiz Dunes Wilderness became part of the now over 109 million acre National Wilderness Preservation System in 1994, and part of the newly designated Mojave Trails National Monument in 2016. Located just 40 miles east of downtown 29 Palms between Highway 62 and the historic Route 66, the road to these pristine sand dunes takes you through some of the most gorgeous locales the Mojave Trails National Monument has to offer. Ever changing in contour and pattern, and spanning nearly 20,000-acres, these majestic and remote sand dunes are shaped by the north winds blowing sand off the Cadiz dry lake. Untouched and unspoiled in beauty, these dunes are home to a unique variety of flora and fauna, including the rare Borrego milkvetch.
Mojave Trails National Monument is home to some of the most well-preserved Desert Training Center training sites and camps, preserving one of the most extraordinary achievements in U.S. military history. Between April 1942 and April 1944, more than 1-million soldiers and 60 armored, infantry and artillery divisions, and fighter pilot and heavy bomber squadrons trained here under General George S. Patton, participating in what is considered some of the most realistic war games ever conducted, under the harshest conditions imaginable. In a very real sense, many battles of World War II were won on these desert lands. *When planning a visit to explore this area of the monument, please do your part to honor, protect, and conserve this area. These public lands serve as a living memorial where the public can learn about this extraordinary chapter in America’s history and the removal of artifacts and use of metal detectors is prohibited.
Mojave Trails National Monument Recreational Opportunities
Remember: Hiking opportunities on BLM lands are vast, but excursions require preparation. Well-maintained signage, visitor centers and gas stations may be few and far between. Always plan your adventure ahead of time and pack plenty of food and water.
Amboy Crater: One of the youngest volcanic fields in the United States, Amboy Crater is home to a National Recreation Trail that takes visitors to the rim of the crater. The route is roughly four miles out and back and is perfect for hiking between the months of October to April. Allow yourself a minimum three hours of hiking time. The cone is one-mile in circumference and is located 1.1 miles from the day use area. Follow the trail to the west of the cinder cone. This will take you to a wide opening where an explosive eruption had breached the crater wall and poured basaltic lava over a 24 square mile area. From here, the climb to the top is an 80-foot incline.
History: The crater is an example of a very symmetrical volcanic cinder cone formed during the Pleistocene geological period and estimated to be 79,000 years old. The most recent eruption was approximately 10,000 years ago. Since the 1970s, the geology of Amboy Crater’s lava fields has been of interest to NASA. The basalt lava fields have been used as test sites for Mars rover missions.
Bonanza Springs: Providing fantastic opportunities for wildlife viewing off the beaten path, Bonanza Springs is located in the foothills of the Clipper Mountains. Fed by the Fenner Basin aquifer, it is the largest spring in the Mojave Desert. Bonanza Springs is surrounded by mesquite and cottonwood trees, cattails and shallow water that supports catfish and bluegil. The spring water stretches for a half mile and provides habitat for frogs and toads. Accessing Bonanza Springs requires 4-wheel drive and a high clearance vehicle. Find more information at blm.gov.
Trilobite Wilderness/Marble Mountains: Rockhounding and invertebrate fossil collecting is a popular, family-fun activity practiced in the Mojave Trails area for the last 100 years. The Marble Mountains, a narrow volcanic range extending 12 miles, contains some of the most-well known Cambrian trilobite fossil sites within California and the Western United States. The fossil beds lie in a beautiful Latham Shale formation that is 60-feet thick and over 550 million years old. Trilobites are extinct arthropods that disappeared approximately 250 million years ago. The small marine crustaceans resemble modern-day horseshoe crabs.
Please follow Bureau of Land Management’s casual use regulations when collecting in the Monument. Find additional information on the Marble Mountains trilobite fossils here. Watch the Rockhounding in the Mojave Trails National Monument video.
Native American History
Mojave Indian Trails: The Mojave Trails area contains remnants of more than 10,000 years of human occupation and has been a critical travel corridor for millennia. The Mojave Indian Trail, used by Native Americans for thousands of years, is the earliest known route passing through the area. Native Americans who have lived in or passed through the Mojave Desert include the Chemehuevi people, the Shosone, Serrano, Kawaiisu, and the Paiute.
Mojave Trails boasts some of the darkest night skies in the California desert. The Bureau of Land Management and its partners are working to get the National Monument identified as an International Dark Sky Sanctuary. Experience the deep, dark night sky for yourself by visiting Amboy Crater. Just a one-hour drive from 29 Palms and located near historic Route 66, the site offers picnic tables, restroom facilities, and an ADA ramada overlook for viewing. Learn more about Mojave Desert Land Trust and their research in Mojave Trails at MDLT.org.
Off-Highway Vehicle Recreation
Mojave Road: This historic 138 mile route follows a series of watering holes across the scenic mojave desert and is increasingly popular with OHV enthusiasts. Mojave Road runs through the Piute Valley portion of Mojave Trails and passes through Mojave National Preserve. With 1.6 million acres of desert in Mojave Trails National Monument and over 1,200 miles of designated OHV routes, there is plenty to explore.
For more info contact the BLM Needles Field Office. Please visit the California Off-Highway Motor Vehicle Recreation site for rules and regulations regarding OHV use in the State of California. To register your off-highway vehicle, please visit the California Department of Motor Vehicles OHV site.
Desert Training Center/California-Arizona Maneuver Area: The DTC was created under the command of General George S. Patton in 1942 to train troops for African, Pacific, and European campaigns. Between April 1942 and April 1944, more than one million soldiers and 60 armored, infantry and artillery divisions, and fighter pilot and heavy bomber squadrons trained in the desert. They participated in what is considered some of the most realistic war games ever conducted under the harshest conditions imaginable.
Camps within the Desert Training Center: Camps Essex, Clipper, Coxcomb, Iron Mountain, Ibis, Granite, Rice and Pilot Knob in California; and Camps Bouse, Horn, Hyder and Laguna in Arizona. The BLM is working to list the Desert Training Center on the National Register of Historical Places. To protect this extraordinary chapter of America’s history, the use of metal detectors/removal of artifacts is prohibited.
Snaggletooth: Mojave Trails National Monument offers expansive opportunities to hike and camp within unique formations made up of igneous, sedimentary and metamorphic rock. This mountain named Snaggletooth, rests in the southwest corner of the Chemehuevi Mountains and serves as a primitive campsite. Due to the beautiful geology and its close proximity to U.S. Highway 95, it is a great place to stay on your way to or from Las Vegas.
