Tent camping opportunities around Fontana, California extend beyond the San Gabriel Mountains into several nearby forest and recreational areas. Campsites range from 4,000 to 7,000 feet elevation, creating significant temperature variations between locations. Winter conditions can bring snow to higher elevation sites, while summer months often see daytime temperatures exceeding 90°F in lower elevation campgrounds.
What to do
Hiking Mount Islip: Access this moderate 3-mile trail from Little Jimmy Trail Campground, where hikers can experience forest-to-peak terrain. "Lots of trails lead from here. Including a 1.2 mike haunt up to a little peak (Mt Islip)," notes Jennifer D., highlighting the interconnected trail system.
Mountain biking: The Exploration Trail near Keller Peak Yellow Post Campsites offers technical terrain for intermediate riders. "The Exploration trail weaves around them up to the peak and makes a great hike and there are tons of climbing spots," explains Kristil C., describing the multi-use trail system.
Fishing year-round: Yucaipa Regional Park maintains stocked lakes for fishing. "Great tent camping facilities, privacy from neighbors, access to Zanja Peak Trail head, 3 lakes for fishing, water park during the summer, and friendly helpful staff," says Bryan H., noting the multiple recreation options.
What campers like
Secluded yellow post sites: Yellow post camping offers privacy with basic amenities. "Located in the Santa Rosa mountain range, the yellow post campsites of Little Thomas are free and offer very minimal amenities. Depending which site you have there's a picnic table. Not much shade on any of the sites so be prepared if going in the summer," advises Shannon C. about Thomas Hunting Grounds Yellow Post Campites.
Hot springs access: Deep Creek Hot Springs provides natural soaking options after a demanding hike. "The hike to the springs is pretty rough but also worth it when you get there," reports For Y., explaining why visitors endure the challenging trail at Deep Creek Hot Springs Campground.
Night sky viewing: Many dispersed sites offer minimal light pollution for stargazing. "Deep in nature, beautiful area, no cost and you can almost always find a spot, even on a Saturday in summer," Nathaniel C. says about Stockton Flats Yellow Post Sites, noting their reliability for impromptu camping trips.
What you should know
Fire restrictions: Regulations vary seasonally and by location. "They are very strict on parties are not allowed. NO FIRES. They have had issues with drug use and parties so thats why they are strict," explains David V. about Keller Peak.
Water access limitations: Most yellow post sites require bringing all water. "There is no larger wildlife, like bears, so less stressful when you have pets or kids. Plenty of space to bring bikes and ride around," notes Mary F. about Yucaipa Regional Park, comparing its amenities to more primitive options.
Road conditions: Many dispersed sites require high-clearance vehicles. "The turn is not marked well, in fact the coordinates are a little bit off. If you miss the turn like we did you have to go 5 miles or more to get a turnabout big enough to turn around," warns Joe R., describing access challenges to Stockton Flats.
Tips for camping with families
Choose established campgrounds: Families benefit from structured sites with facilities. "Lovely little place! Super close to the lake, secluded up in the mountains," says Alisa B. about Green Valley Lake Recreation Area, highlighting its accessibility for families.
Consider seasonal attractions: Some locations offer additional recreation during summer. "Went here a few years ago, and was a little disappointed. The site was fine; relatively even, fire pit, lots of gorgeous tree cover, but if you're going to call it 'green valley lake' I'd better be able to see the lake. Instead, it was a twenty minute car ride to the lake," cautions Bradley W. about Lake Arrowhead - Green Valley Lake Recreation Area.
Wildlife encounters: Prepare for local wildlife encounters. "We spent 3days and 2nights here and enjoyed our stay, the caretaker was so nice! Although the restroom are very dirty but overall it was a great stay!" mentions Ella Z. about Manker Campground, noting the trade-off between amenities and nature immersion.
Tips from RVers
Limited RV access: Most dispersed sites near Fontana can't accommodate larger vehicles. "I got the very first spot. It's a bit of a drive but very scenic and should be doable in any car. My campsite was big and spacious and looked up at an outcropping of rocks," explains Jillian about Keller Peak, noting the accessibility for standard vehicles versus RVs.
Seasonal temperature variations: Higher elevation sites experience significant temperature swings. "Weather is definitely colder than in the valley, got snow overnight in mid May," Jillian continues about Keller Peak, providing important climate context for RV campers planning water systems protection.
Hook-up availability: Full-hookup options are limited near Fontana. "We're usually full-time boondockers, and this was the first time we've paid for an RV park, so we don't have a lot to compare it to. But overall it's been a pleasant stay. Lots of shade, a pond, and reasonable rates. Good water pressure in the showers, which has been nice. Most private RV spots discriminate against Skoolies, but this place didn't seem to care," notes Jason O. about Yucaipa Regional Park.
