Best Dispersed Camping near Rialto, CA
Several free dispersed camping options exist in the mountains northeast of Rialto. Rim of the World Byway provides accessible sites right off Interstate 15, suitable for quick overnight stops. The area sits near train tracks and Mormon Rocks, with some sites requiring 4-wheel drive for access. As one camper notes, "Easy in and out but next to train tracks. Quick stop friendly."
East Flats offers more remote camping with multiple level sites that can accommodate various vehicle sizes, including some suitable for larger RVs. The dirt roads require moderate clearance but remain accessible to most vehicles in dry conditions. Mill Creek Dispersed Camping provides another option near Big Bear with numerous flat spots along forest service roads. However, access requires navigating gravel roads with potholes and steep sections. One reviewer cautions, "The road up to the actual spot is gravel, with lots of potholes and washboard areas, which would make it difficult for an RV." Most sites have no amenities—no water, toilets, or trash service—and fire restrictions commonly apply. Permits are required for camping in the San Gorgonio Wilderness areas.
