Picketpost Mountain Road to Superior Backcountry — Tonto National Forest Desert Spine via Telegraph Canyon
Sonoran Desert canyon country, no crowds.
East of Superior, Arizona, the Tonto National Forest opens into a maze of two-track jeep roads cutting through dense saguaro forest, ocotillo flats, and the eroded drainages of Telegraph Canyon. The Picketpost Mountain trailhead sits at roughly 2,400 feet, and the route climbs the bajada northeast through FR 4, threading narrow canyon washes before reaching high benches with unobstructed views of the Superstition Wilderness to the north. Telegraph Canyon itself throws rocky ledge drops and loose basalt cobbles at you — nothing that’ll end your trip, but enough to wake you up. Picketpost Mountain’s 4,375-foot volcanic plug towers over the whole circuit as a constant landmark.
This is a moderate high-clearance run best suited to stock 4WD rigs with all-terrain tires — a lifted rig makes it more comfortable but isn’t mandatory. Wash crossings are usually dry but can run fast after monsoon storms; avoid July-August flash flood windows. Best seasons are October through April. No permit required. Fuel in Superior before you go — there’s nothing out here. Cell service drops to zero once you’re in the canyon. Dispersed camping is available on national forest land away from the washes. What you get is pure Sonoran Desert solitude ten miles from a highway.

Frequently asked questions
Can a stock 4Runner or Wrangler handle this without any lift?
A stock high-clearance 4WD will get through, but Telegraph Canyon's rocky wash sections will test your skid plates and low-range crawling. Lifted rigs with all-terrain tires will have noticeably more margin — a bone-stock crossover SUV has no business here.
When is this trail actually drivable — and what kills access?
October through April is the window. Summer monsoons turn the wash crossings into fast-moving hazards and can make the dirt sections impassable for days. Check recent conditions with the Globe Ranger District before heading out in shoulder months.
Do I need a permit or pay any fees to run this trail?
No permit required and no day-use fee for this route through Tonto National Forest. Standard forest rules apply — pack out your trash, follow fire restrictions, and don't cut new tracks off the existing route.
What's the hardest section and what should I actually expect?
Telegraph Canyon is where it gets real — you're driving the rocky wash bed itself, hopping boulders and navigating tight canyon walls with limited room to maneuver. Approach angles matter here, and a high-centered recovery in a confined canyon is a bad time, so pick your lines before you commit.
Is there any water or gas near the trailhead, and how far is the nearest fuel?
Superior, AZ is your last stop for gas and supplies — fill up there before you roll out because there is zero cell service on trail and no water sources you should count on. Carry at least 2 gallons of water per person for a day run in this desert heat.
