The Castle Mountains National Monument is located in the eastern Mojave desert in San Bernardino County, California, and is bordered on three sides by the Mojave National Preserve. The park was established in 2016 along with two other neighboring national parks, Mojave Trails National Monument, and Sand to Snow National Monument. Castle Mountain National Monument is the only park of the three that is managed by the National Park Service, and it protects 20920 acres of natural area and desert ecosystem, northwest of the Colorado River.
The monument surrounds an open pit gold mine, which will transfer to the park service when mining is completed. The main attraction in the park is the Castle Peaks, a group of spires that jut upwards, a unique geological formation that is popular with sightseers. Mojave desert grasslands, dense juniper forests, and Joshua trees lie at the foot of the mountains here. The stunning desert scenery is also habitat for area wildlife, and there are historical and archaeological sites in the area that are interesting to explore.
The park is open year round, there are no facilities at the park, no WiFi available, and cell phone reception is spotty. The visitor centre in the adjacent Mojave National Preserve provides information on the Castle Mountains National Monument area.

Castle Mountain National Monument is a 90 minute drive south of Las Vegas, and a four hour drive east of Los Angeles. The park can only be accessed by dirt roads, and four wheel drive vehicles with high clearance are recommended. Dirt roads can become more treacherous in inclement weather so be sure you have the appropriate gear and equipment to access the park.

Seasonal activities in Castle Mountains National Monument
The desert habitats in the region which includes grasslands, forest, and mountain terrain are home to a variety of wildlife. This region is also part of the 226 square mile Lanfair Valley watershed which provides an aquifer that is critical to wildlife in the Mojave desert ecosystem. Eagles, bighorn sheep, mountain lions, coyotes and bobcats are some of the exciting creatures you may spot in the Castle Mountains National Monument region.
Also, keep an eye out for a variety of reptiles, birds, and insects that make the park area their home. Use caution and keep your distance from large mammals and rattlesnakes which are poisonous. Keep a respectful distance and use the zoom feature on your camera rather than crowding the local inhabitants!
Mountains, spires, Joshua trees, juniper forests and desert grasslands combine to create wonderful scenery and landscape views in the Castle Mountains National Monument area. The combination of Mojave desert features in the area is unique as few sites combine such diverse geological formations and natural habitat. The Castle Peaks spires which soar up into the sky are a particular favorite spot for visitors to do some interesting sightseeing. Enjoy the scenery and bring a camera to record your desert trip.
Several significant Native American archaeological sites have been discovered in the Castle Mountain National Monument area. There is also a historic gold mining ghost town, Hart, nearby. The gold mining town gives visitors insight into the hardships of settlement in this harsh desert environment.
Check out information on these sites at the nearby visitor center in the Mojave National Preserve. Prehistoric rock art and other signs of early Native American settlements can be found in the region. There are also signs of wagon train trails, and past cattle ranching activities including corrals and watering troughs. Take along a notebook and a camera to record your exploration!
Crisp, clear nights in the Mojave desert during the autumn months make for perfect stargazing conditions. The relatively secluded landscape of the Castle Mountains National Monument has a minimum of light noise from local civilization, which makes it easier to see the stars at night.
Take along a star chart to identify constellations and heavenly bodies as cell service is not reliable in the area and stargazing apps on your devices may not be useful. Take along some warm outerwear as the desert gets cold at night later in the year.
The local equestrian campground allows riders and their four-legged friends to camp near the Castle Mountains National Monument and explore the surrounding areas. The rugged terrain is best accessed on four legs, not two! There are elevation changes and rough ground so ensure your horse is fit for treks in the region. Cooler weather later in the year will make it easier to avoid overheating your horse while riding in the desert landscape which can be hot and unforgiving during summer months.
Several of the paved and unpaved routes in the region are known for their scenery and are popular auto touring sites. Castleview Drive is the paved section of Highway 164 between Nipton and Searchlight, and takes you through dense Joshua tree forests. Ivanpah Road and Lanfair Road take you through the Lanfair Valley, the pavement ends, and vehicles with high clearance are recommended for travel in the area. Cedar Canyon Road is a maintained dirt road through scenic Lanfair Valley that may be a better option. Mojave Road was once an overland route bringing pioneers to California. This route is very rugged and appropriate for 4WD vehicles only.
