California Highway 78 cuts across Southern California and right thru the middle of the largest State Park in the lower 48. Anza Borrego Desert State Park is a place that must be visited more than once to really take in all the beauty it has to offer. Free camping in Southern California is abundant here, if you are willing to follow the primitive camp fire rules of the park and you are comfortable camping away from developed campgrounds.
North-South:San Diego County Road S2 skirts the western border with Laguna Mountain towering above. It starts at Ocotillo @ Interstate 8 and heads Northwest to Lake Henshaw at Warner Springs.
East-West: a major route S22, connects Ranchita /Montezuma Valley to the Borrego Valley, and continues East to the Salton Sea. The center of the parks is pretty much the town of Borrego Springs, where the State Parks visitors center is located. San Diego County Road S3 leads from Hwy 78 down the the town of Borrego Springs Valley.
free camping: While the camping facilities listed above provide picnic tables and toilets, or more luxury camping… Total Escape thinks the best part of camping in Anza Borrego Desert is the vast amount of free, open camping available on most back roads. Hundreds of dirt roads lead off in all directions, so you can find the peace and solitude that few inside busy campgrounds ever experience.
Many Anza desert routes are sandy washes, dirt roads, some for high clearance vehicles only, or 4WD in several canyons. Often there is no signs telling you need 4×4 to proceed. May only find out when its too late and you’re stuck.
Have a good dirt road map with you and know your vehicles limitations. Passenger cars should be very cautious off road. Cell phone coverage is spotty out here in the most remote wilderness areas.

BLOOM: February thru May Anza Park elevations range from low to high. Lowest near eastern border of park (next to the Salton Sea) to the upper reaches of the western slopes @ 4000′ of the Laguna mountains. Lower elevations sprout up first; Micro flowers, Easter-egg-color splendor in the dry washes. Higher elevations bloom later (along w/ areas on San Diego County Rd S-2, the Great Overland Stage Route)
Drive from Temecula to Warner Springs, and then proceed east – out to the Salton Sea via Back Road Highway #S22 (Montezuma Grade). A great route to take thru the Borrego State Park – for the full gamut in vegetation & altitude. Grapevine Canyon is an alternate off road route down a scenic canyon. Culp Valley has a small campground, plus lots of boulders and decent views to the Borrego Valley. Off the highway, on dirt, one-lane side roads lead to many primitive spots. Perfect for private picnics, stargazing or overnight camping.
