Borrego Mountain Wash to Arroyo Salado — Anza-Borrego Badlands Desert Circuit via Seventeen Palms
Badlands, palms, and painted clay at the edge.
Borrego Mountain Wash drops you into the heart of Anza-Borrego Desert State Park’s badlands country within a mile of the pavement on DiGiorgio Road. The route runs east through eroded clay walls and sandy wash floors before climbing onto the open bajada toward Seventeen Palms Oasis — a cluster of native fan palms fed by a fault spring in the middle of pure desert hardpan. The oasis itself is eerie and beautiful in equal measure: green life in a landscape that otherwise looks like Mars. From Seventeen Palms, the route connects northeast through Arroyo Salado wash, passing multi-colored badland formations that glow orange, purple, and bone-white in afternoon light before looping back toward the highway.
Difficulty is Moderate, but sand depth in the washes can spike conditions quickly after summer monsoons pile sediment. A high-clearance 4×4 with aired-down tires is the minimum — 4WD is mandatory when wash sand is soft. The park requires a day-use fee; no permit needed for backcountry camping in designated sites. Best run October through April; summer temperatures routinely exceed 110°F and become genuinely dangerous. Water is scarce — Seventeen Palms spring is not potable. Carry everything you need. The color, isolation, and geological spectacle in this corner of Anza-Borrego rival anything in the California desert system.

Frequently asked questions
Can a stock Tacoma or 4Runner run this trail, or do I need a lifted rig?
A stock high-clearance 4WD will handle it, but you must air down to 15-20 PSI for the soft sand sections in Borrego Mountain Wash — skipping that step is how people get stuck. A lift helps but isn't required; what matters more is locking hubs engaged and a patient throttle foot.
Is this trail runnable in summer, or will it wreck me?
Summer is genuinely dangerous here — July and August temps regularly hit 110°F+ in the wash with zero shade for most of the route. Stick to October through April; even a warm spring day in March can push 95°F in the badlands, so early morning starts matter.
Do I need a permit or pay a fee to run this route?
No permit is required for day use or dispersed camping in Anza-Borrego Desert State Park — it's one of the few California State Parks where that's still true. There's no fee to enter the backcountry, but if you camp, you're limited to 30 days per year total in the park and must stay on existing roads or previously disturbed ground.
What's the hardest section, and what makes it technical?
The loose sand in the main wash channels is where most rigs get into trouble — it's not a rock crawl, it's a momentum and tire pressure game. Commit to your line, stay aired down, and don't stop in deep sand; the clay formation sections are rougher on the frame but slower-speed and more forgiving.
Is there any water at Seventeen Palms, and how far is the nearest gas from the trailhead?
Seventeen Palms has a natural seep that supports the palms, but it is not potable — bring everything you need, minimum 1 gallon per person per day plus extra for the vehicle. Borrego Springs is the only nearby fuel stop, roughly 10-15 miles from the trailhead, and it's the last chance before you drop into an area with zero cell service for the entire route.
