Several dispersed camping areas surround Big Bear Lake east of Fontana, California, with East Flats being particularly popular for its level terrain and accessibility. This free camping area accommodates vehicles of various sizes, including 34-foot Class A motorhomes, while offering enough space between sites for privacy. The dirt roads are generally navigable, though some rougher sections benefit from higher clearance vehicles. A review mentioned, "There are a number of campers, but remote locations are easily found."
Mill Creek Dispersed Camping provides another option with numerous campsites spread along forest service roads, though access requires consideration. The main road is paved, but the final approach features gravel with potholes and washboard sections. A steep section with a hairpin turn limits larger vehicles. As one camper noted, "There are over a dozen sites along the main road. If you can pull in, it's a site." Rim of the World Byway offers more accessible sites for those seeking quick access from Interstate 15, while Stockton Flats Yellow Post Sites require 4x4 vehicles but reward with deeper forest immersion. No facilities, water, or trash service exist at these locations, and fire restrictions frequently apply.
