The High Desert region surrounding Adelanto sits at approximately 2,900 feet elevation in the western Mojave Desert, experiencing temperature swings of up to 40 degrees between day and night during seasonal transitions. Winter temperatures regularly fall below 25°F between December and February, requiring propane heaters for tent campers and insulated water hoses for RV campers. Camping options extend beyond traditional RV parks Adelanto, California, with numerous dispersed sites available in surrounding public lands.
What to do
Hiking to waterfalls: Access Bonita Falls via trails behind Bonita Ranch Campground. "Easy access to a pretty trail right behind the campground. Very quiet and interspersed with long time stayers and temporary campers," notes Heather L. The falls can get crowded on weekends, particularly during summer months.
Mountain biking: The San Bernardino Mountains offer numerous mountain biking trails suitable for various skill levels. Keller Peak Yellow Post Campsites serves as an excellent base for cyclists. "The Exploration trail weaves around them up to the peak and makes a great hike and there are tons of climbing spots," reports Kristil C.
Lake activities: Fishing is permitted at multiple lakes within 45 minutes of Adelanto. "There's camping, horseback riding, fishing, trails, biking, hiking, picnics, you can use your jet skies in designated areas, swimming on the pool areas, kayaking," mentions Jessica P. about recreational options at nearby lakes.
What campers like
Affordable options: Budget-conscious campers appreciate the Yellow Post sites in the mountains. "Free camping in the San Bernardino mtns...I got the very first spot. It's a bit of a drive but very scenic and should be doable in any car," shares Jillian about Keller Peak Yellow Post Campsites. These sites typically fill by early afternoon on summer weekends.
Security features: Gated RV parks provide peace of mind for travelers with valuable equipment. "Great sense of community and great placement of the gates for safety purposes. Lots of food spots within 10 minutes. Spaces are one of the cleanest I seen. Ranger is on constant patrol," writes Troy A. about Rancho Jurupa RV Park.
Mountain views: Many camping locations offer expansive vistas across the Mojave Desert and San Bernardino Mountains. "Beautiful views all around Sunrise, Sunset and Night sky. Sights of all kinds of birds like hawks and herons," notes Xochiquetzal G. The clearest views typically occur October through April when dust storms are less common.
What you should know
Weather extremes: High Desert temperatures fluctuate dramatically by season and time of day. "It was down in the 40s last night, but our traveling bed is a cushy cloud," shares Michelle M. about her stay at Shady Lane RV Camp. Afternoon temperatures regularly exceed 100°F from June through September, while nighttime lows below freezing occur December through February.
Cell service variability: Coverage can be inconsistent depending on carrier and specific location. "Had very bad but there at&t cell reception. Nice and quiet with space between spots," reports Jillian about her stay in the mountains. Verizon typically provides the most reliable coverage throughout the region.
Water availability: Most dispersed camping areas have no water sources. When staying at yellow post sites, bring 1 gallon per person per day minimum. "No water" is noted as a feature at several mountain camping areas, requiring advance planning and sufficient water storage.
Tips for camping with families
Water activities: Children particularly enjoy splash pads and swimming areas at developed campgrounds. "Water park and mini golf for kids. Showers and laundry convenient. Camping spots all have fire pit and spacious area for RVs and tents," says Xochiquetzal G. about Thousand Trails Soledad Canyon.
Safety concerns: Some areas require extra vigilance with children. "We were site261 cottonwood. Only downside was that the ranger said to lock up bikes and be careful leaving out items because a local has been coming in stealing," warns Marcella D. Always secure valuables, particularly bicycles and portable electronics.
Group camping challenges: Scout groups and family reunions face particular considerations. "Took Girl Scouts here for group camping. Rocky and sand. The family camping was fine! Girls used Porta Potties. I'm hoping they have finished construction on something better since then. However, there are some great kid friendly activities," reports Janet S.
Tips from RVers
Access road considerations: Mountain roads can present challenges for larger rigs. "It's no joke pulling a trailer up there. Make sure you take the back way up the mountain," advises Kevin B. about accessing Holloway's Marina & RV Park. High-profile vehicles should avoid mountain routes during high wind advisories.
Site selection strategies: RV parks near Adelanto offer varying site conditions. "Sewer inlet was a bit high. Had to lift my hose many times to drain fully. Asphalt pad with gravel picnic area between pads. Pad was a little off level. Had to block one side," shares Jesse C. Request specific sites when making reservations if leveling is a concern.
Temperature management: Extreme seasonal temperatures require preparation. "We stayed down near the welcome center instead of Lot N and the experience didn't even seem like the same RV Park. No loud music, no barking dog, less dust, and dirt," notes Keisha D. Sites with shade trees provide up to 15°F cooler temperatures during summer months.
