Tonto Natural Bridge Road to Pine Creek Canyon — Tonto National Forest Rim Country Descent via Payson Backcountry
The world's biggest travertine bridge, earned.
Most people hit Tonto Natural Bridge State Park from AZ-87 and call it a day, but the backcountry approach via the Tonto National Forest rim roads northwest of Payson tells a different story. The old forest road system off FR 405 and Pine Creek Road drops you through juniper-pinyon woodland into a steep canyon system where travertine has been building for thousands of years. Pine Creek itself cuts through the heart of it, and the approach requires crossing the creek multiple times before the canyon walls close in and the bridge — 183 feet high, 400 feet long — appears overhead. It is genuinely impressive terrain that rewards drivers willing to leave AZ-87 behind.
This is a high-clearance route with moderate technical difficulty — rocky descents, seasonal creek crossings, and loose canyon-bottom terrain require a capable rig with at least 8 inches of clearance and a locking front differential on wet days. Spring runoff makes crossings unpredictable; late September through November is the sweet spot. No permits for the forest road approach, but the state park charges a day-use fee if you enter from that side. Payson is 12 miles south for fuel and supplies — fill up there. Cell service dies fast once you’re in the canyon.

Frequently asked questions
Can a stock 4Runner or Jeep Wrangler handle this trail without modifications?
A stock high-clearance 4WD like a 4Runner or Wrangler will get through, but the rocky descent into Pine Creek Canyon has ledges and loose rubble that demand genuine 4-low use. Lifted rigs with skid plates will have more margin; a bone-stock crossover SUV does not belong here.
What's the best time of year to run this trail and when should I avoid it?
September through November is the sweet spot — heat has broken, the creek crossings are typically manageable, and fall color adds to the canyon views. Avoid July and August when monsoon rains make the descent slick and Pine Creek can flash flood with zero warning.
Do I need a permit to drive this trail or visit Tonto Natural Bridge?
The backcountry road through Tonto National Forest requires no permit, but Tonto Natural Bridge State Park at the bottom charges a day-use fee (currently $7/vehicle). If you're camping dispersed on National Forest land en route, no permit is needed but standard 14-day stay limits apply.
What's the hardest section and what should I actually expect?
The steepest, roughest stretch is the rocky descent into Pine Creek Canyon — loose shale over embedded rock shelves with limited room to correct a bad line. It's not a white-knuckle trail, but one wrong tire placement on the descent can hang a rocker panel or high-center a short-wheelbase rig.
How deep are the Pine Creek water crossings and is there a gas station close to the trailhead?
Pine Creek crossings typically run ankle-to-knee deep in fall, but after monsoon season they can surge significantly — check conditions before you drop in because there's no easy turnaround once you're committed to the canyon. Fuel up in Payson before you leave; it's the last stop, and you're looking at a full day with no services on trail.
