Rialto sits at the foothills of the San Bernardino Mountains with elevations ranging from 1,100 to over 4,000 feet in nearby camping areas. Winter temperatures can drop below freezing at higher elevation sites, while summer days often exceed 90°F in the valley. Most campgrounds in this region enforce strict fire regulations during dry months due to high wildfire risk.
What to do
Hiking to Bonita Falls: The trailhead is accessible from South Fork Road near Bonita Ranch Campground. "Cozy getaway in San Bernardino Forest with beautiful hiking trails and waterfall," notes Justin I., who gave the site five stars. The falls are approximately 1.8 miles roundtrip from the campground.
Mountain biking at Lake Arrowhead: Trails range from beginner to advanced with multiple access points. "There is camping, horseback riding, fishing, trails, biking, hiking, picnics, you can use your jet skies in designated areas, swimming on the pool areas, kayaking, Park for kids and plenty more," writes Jessica P. about recreation options at Bonelli Bluffs.
Winter camping with views: Several sites offer year-round glamping close to Rialto, California with snow potential. "We camped here the last weekend before they closed for the winter, after Thanksgiving. The campground was clean, quiet, and had a decent amount of space between sites. There is a biking trail that goes through the campground that was well used," reports Nicole W. about her experience at Serrano.
What campers like
Forest solitude: Many sites offer secluded camping with minimal neighbor contact. At Keller Peak Yellow Post Campsites, "There are only 9 sites stretched across 5 miles so you will have no neighbors. Each site is decent size and tucked away into the rocks. Many will fit multiple people easily," explains Kristil C. Sites fill quickly May through September.
Well-maintained facilities: Even primitive sites typically have clean restrooms. "The sites are well spaced, good tree cover. Very nice patch of land. Quiet. Lake Arrowhead Village is 4 miles away," notes Andrew B. about North Shore Campground - Lake Almanor, describing its natural setting and proximity to services.
Wildlife viewing opportunities: Morning and evening hours offer the best wildlife sightings. "We loved camping here. Beautiful, pristine campground with bike trails/walking paths around the lake. The town is bike friendly. Some road noise but quiet over night. Weather is perfect in August," shares Trey T. about his experience at Serrano.
What you should know
Fire restrictions vary seasonally: Always check current rules before arrival. A camper at Mojave River Forks Regional Park notes, "Nice place to camp, weather is around 75 during the day and about 50 to 36 degrees cold throughout the night. Has everything you'll need. Bathrooms are close by, showers HOT water available."
Weekend crowding at popular spots: Reservations strongly recommended Friday through Sunday. "It was quite clean and fun. Took my son and his girlfriend with us a great place for families," comments Amanda A. about her experience at a campground in the area.
Cell service limitations: Coverage varies dramatically by location and carrier. "T-Mobile signal was poor and Verizon and AT&T cell signals were slightly better," reports one camper about connectivity at Mojave River Forks Regional Park, an important consideration for those requiring connectivity during their stay.
Tips for camping with families
Look for sites with playground access: Several campgrounds include kid-friendly facilities. "This campground is great. Me and my wife stay here a couple times a year and we also bring our grown kids and with our little grandkids," shares Steven E. about his regular visits to Serrano.
Consider hot springs alternatives: Some thermal areas like Deep Creek Hot Springs are clothing-optional. "The hot springs is clothing optional, so if you don't mind naked people, or you wanna strip down yourself, you should go check it out," warns Jake P., noting important information for families.
Reserve sites away from access roads: Request specific site numbers when booking. "We initially thought they double charged me, went to clarify only to realize the 2nd charge was for the 2nd night. So for 2 nights it was $142! Not worth it," mentions Michael S. about pricing at one popular campground, highlighting the importance of understanding costs.
Tips from RVers
Limited full hookup availability: Book well in advance for premium sites. "We chose Bonelli for our shakedown trip in our new trailer (first time RVers). SO quiet. Numerous residents, but spots are mostly keep up nicely. Our rental spot has 3 trees, a picnic table, a firepit, level parking(!) and full hookups," reports Aostara K. about her experience at Bonelli Bluffs.
Consider RV size limitations: Many roads to glamping spots near Rialto are narrow or winding. Dennis B. notes, "A little pricey but very nice facility. All hookups 30/50 amp. Cable TV. There's a pool. A tent area. Some spaces monumentally better than others."
Winter water line freezing: Higher elevation sites may require additional preparation. "Our sewer outlet was frozen in the morning, so we had to dump when we got out of the mountains," reports Nicole W. about a winter camping experience, highlighting a common cold-weather challenge for RVers.
