Overview
Mazatzal Peak at 7,903 feet is the high point of the Mazatzal Wilderness, one of seven wilderness areas in the Tonto National Forest. The 12-mile round-trip trail that reaches it is the most demanding day hike in central Arizona: 3,500 feet of elevation gain through terrain that transitions from Sonoran Desert floor to subalpine chaparral and finally to open rocky summit country. On a clear day the summit looks west across the entire Phoenix metropolitan area, south to the Superstition Wilderness, north to the Mogollon Rim, and east into the New Mexico mountains.
The trail's difficulty and the remote location filter all but committed hikers. Solitude on the upper mountain is essentially guaranteed, even on weekends. But the commitment is genuine: this is a 9-12 hour day for most hikers, with heat exposure in summer that makes the hike genuinely hazardous below the wilderness zone.
Heat is the overriding concern for timing. Lower trailhead elevations sit in the Sonoran Desert transition zone where summer temperatures exceed 100 degrees Fahrenheit. Many hikers carry 4 liters of water for this route; individual hydration needs vary significantly with temperature; do not underestimate water requirements in warm conditions. October through May is the practical season. Monsoon season (July through September) adds flash flood risk in the lower canyon sections.
The Route
Miles 0 to 3.0: From the trailhead, the route climbs steeply through Sonoran Desert scrub. Saguaro cactus, ocotillo, and palo verde define the first mile. The trail gains elevation rapidly as it moves into the foothills chaparral zone. Water at a seasonal creek crossing around mile 2 provides the only reliable water possibility on the route; treat any water before drinking.
Miles 3.0 to 6.0: The wilderness boundary is passed around mile 3 and the terrain opens. The climb continues through the upper chaparral and onto the rocky ridge system leading to the summit. Views expand dramatically in this section. The desert basin is visible below to the west.
Miles 6.0 to 12.0 (return): The summit delivers the full 360-degree panorama. The return trip is considerably more demanding physically after 6 miles of climbing. Manage reserves carefully; tired legs on rocky descent terrain are where most injuries happen.
When to Visit
October through May. The lower desert terrain makes summer visits seriously hazardous. Even in the shoulder season of May, starting before 6 a.m. is advisable to complete the lower desert section before temperatures rise.
Winter (December through February) is viable on mild days. The summit can hold snow and ice. Micro-traction devices (microspikes or similar) may be needed for the upper rocky sections in cold weather.
Spring (March through April) offers the desert wildflower season on the lower slopes. This is the most visually rewarding time to hike the lower half of the route.
What to Bring
- Water: many hikers carry 4 liters for this full-day strenuous hike; individual needs vary with temperature; carry more than you think you need
- High-calorie food: 9-12 hours on trail demands substantial nutrition
- Headlamp: essential for pre-dawn starts
- Trekking poles: strongly recommended for 3,500 feet of descent on rocky terrain
- First aid kit with blister care
- Emergency bivy: the remote location and long day make an emergency preparedness mindset appropriate
- Tonto Pass ($8/day as of 2026)
Review bear canister requirements for overnight trips in the Mazatzal Wilderness. The wilderness sees enough bear activity to make proper food storage a genuine consideration.
Practical Details
Tonto Pass required at the trailhead as of 2026. No wilderness permit required. Review Leave No Trace 7 principles for wilderness area conduct.
Cell service is absent in the wilderness. A personal locator beacon (PLB) or satellite communicator is strongly recommended for solo and small-group parties. Emergency response times in the Mazatzal Wilderness are measured in hours, not minutes.
Getting There
From Phoenix: Take AZ-87 north approximately 45 miles past Fountain Hills. Look for the signed Mazatzal Peak trailhead turnoff on the west side of the highway. The paved parking area is visible from the road.
From Payson: Take AZ-87 south approximately 25 miles to the trailhead. Check current conditions and Tonto Pass vendor locations before your trip. See checking conditions before you go for ranger district contacts.
