Trail Overview

Pinyon Mountain Road is an 8.8-mile point-to-point trail in Anza-Borrego Desert State Park, designed for experienced off-roaders. The first 6.5 miles climb into Pinyon Mountain Valley and allow two-way traffic. Past the valley, the trail becomes a strict west-to-east one-way route featuring extreme obstacles. The first major obstacle is "The Squeeze," an 83-inch-wide rock gap on an off-camber descent. This is followed by a rugged rock garden, a waterfall climb, and "Heart Attack Hill"—a steep, rutted drop-off. The route ends at the junction of Hapaha Flats Road and Pinyon Wash. Four-wheel drive, high ground clearance, at least 33-inch tires, and traction lockers are required.

Difficulty

The trail's surfaces are rutted, rocky, and sandy with steps not exceeding 24 inches, with considerable slickrock surfaces. Water does not exceed 12 inches, but some mud is possible. Good ground clearance and driving skills are needed. 4WD, tall tires (33-inch plus), and traction-adding devices (locker, limited slip) are required. Above-average driving skills are desirable. A winch would be a plus. Enhanced suspension travel and good ground clearance are also required.

History

Anza-Borrego Desert State Park is California's largest state park, encompassing nearly 600,000 acres of the Colorado Desert. Its name honors the 18th-century Spanish explorer Juan Bautista de Anza and 'borrego', the Spanish word for the region's native desert bighorn sheep. The vast, protected wilderness features dramatic badlands, rugged mountains rising up to 5,500 feet, and rich desert ecosystems inhabited by golden eagles, kit foxes, and bighorn sheep.

Great mid grade trail. YouTube got us all hyped about the squeeze, hear attack mountain etc, but it’s challenging at best and not difficult at all. Super good time. Careful with the window breaker.

Washout
Started at Canon Sin Nombre up past Hapaha Flat and then picked up the Pinon Mtn. Trail. Dead stop at the base of Heart Attack Hill. Post-hurricane, the descent is now deeply rutted, smooth and in most places without sand, rock or gravel. The old cement slab is now 6 to 8" above the face of the hill, the rest having been washed away. If there was water running down the old road bed, left or right, we'd call it a waterfall. For anybody except the most experienced with the most technical of rigs, driving up is impossible. I wouldn't even drive down it now. Be very, very careful with your choices here. One false move and you and your life could end up tumbling down the equivalent of a six story building.

Very mild easy trail through beautiful desert until you get to the squeeze. My 93 land cruiser is a little too wide to make it past the rocks without damage. My buddies jeep made it through without damage but he was already missing his back fender which helped. My track width is 80 inches and his is about the same, but his jeep is narrower body where it counts. Tire less than 35's probably need sliders.

Few new boulders came down in a few spots, definitely a challenge but still passable.

Trail is largely fairly mild, but has a section that is much more technical by comparison. The section starting from "The Squeeze", through to a very steep at deeply rutted downhill section provides some challenge that will require significant articulation and some careful driving to avoid body damage. Awesome trail! As an aside, be mindful of the heat during the day, and bring lots of water.

great trail! shimmy your driver wheel down into the crevice when passing through the squeeze to pull your passenger fenders off the boulder. when hitting heart attack Hill don't take the right hand entry unless you have longer wheelbase. two doors are better off taking the left hand line even though it's slightly harder to enter.
