The trail to Arizona's highest point (12,633 ft) begins at Snowbowl ski area and climbs through spruce-fir forest, past the treeline, and across a tundra-like saddle to the summit with views across four states. Sacred to both Navajo and Hopi peoples.
Humphreys Peak Trail ascends to the summit of Arizona's highest point at 12,633 feet (3,851 meters), climbing through multiple ecological zones in the Kachina Peaks Wilderness of Coconino National Forest near Flagstaff. The trailhead begins at the Arizona Snowbowl ski area on Snowbowl Road, approximately 14 miles north of Flagstaff; parking is free and the trailhead is well-marked. No permit is currently required to hike Humphreys Peak.
The trail climbs 885 meters over 7.75 miles one way, beginning at the base of the ski area at approximately 9,200 feet elevation. The lower section passes through dense subalpine forest of Engelmann spruce, corkbark fir, and quaking aspen on a well-maintained path with periodic trail markers. Above approximately 11,000 feet the trees thin into krummholz — dwarfed, wind-sculpted conifers — and the trail enters open tundra and scree fields. The final approach to the summit ridge is on loose volcanic scree and pumice, requiring careful footing.
The summit lies on a narrow ridge connecting Humphreys Peak to Agassiz Peak. Views from the summit encompass the Colorado Plateau, Painted Desert, the Grand Canyon (on clear days), and across parts of Utah, Colorado, and New Mexico — four states potentially visible from a single point. The San Francisco Peaks are sacred to multiple Native American peoples: to the Navajo Nation they are Dook'o'oosłííd (one of the four sacred mountains), and to the Hopi they are the spiritual home of the kachina spirits. Visitors are asked to treat the summit area with respect and to avoid removing any natural materials.
Summer afternoon thunderstorms are the primary safety hazard above treeline; lightning strikes on the exposed summit ridge have caused fatalities. The optimal strategy is to summit by noon and descend below treeline before afternoon clouds develop, which typically occurs between 1pm and 3pm during the July–September monsoon season.

Tips for visiting
- Aim to reach the summit by noon and begin descent by 12:30pm to avoid afternoon lightning on the exposed summit ridge.
- Start hiking no later than 6am during July–September monsoon season; afternoon thunderstorms typically develop rapidly.
- Acclimatize by spending at least one night in Flagstaff (6,910 ft) before attempting the summit — the 12,633-foot altitude is significant for visitors arriving from sea level.
- Carry extra layers; summit temperatures can be 20–30°F colder than Flagstaff with strong winds year-round.
- Snow covers the upper trail from November through May — microspikes or crampons and trekking poles are necessary in those months.
- Carry at least 2 liters of water and a filter; a seasonal spring exists near the treeline but should not be relied upon as the only source.
When to visit
Late June through early October offers the clearest summit views; September and early October are the safest windows with fewest weather hazards and good snow-free conditions.
Accessibility
Humphreys Peak Trail is not wheelchair accessible. The trail climbs steeply through forest and then across open scree and tundra with rough surfaces throughout. The Snowbowl ski area base has accessible parking and restrooms, but the trail itself is entirely non-accessible.
Frequently asked questions
Is Humphreys Peak the highest point in Arizona?
Yes. Humphreys Peak at 12,633 feet (3,851 meters) is the highest summit in Arizona and the highest point in the Colorado Plateau region. The summit is part of the San Francisco Peaks volcanic field northeast of Flagstaff.
When is the trail free of snow?
The lower forested sections are generally snow-free from late May, but the upper scree fields and summit ridge typically retain snow until late June or even early July in heavy snow years. The trail is accessible without special gear from late June through October in most years.
Is the trail sacred and are there any restrictions?
The San Francisco Peaks are sacred to multiple Native American peoples including the Navajo and Hopi. The trail is currently open to hikers, but visitors are asked to avoid removing rocks, plants, or other natural materials and to treat the summit area respectfully. Check Coconino National Forest for any current closures or restrictions.
What gear is needed for Humphreys Peak?
In summer (July–October): sturdy hiking boots, layers for cold summit temperatures, rain gear, sun protection, trekking poles, and at least 2 liters of water. In late autumn through spring with snow: microspikes or crampons and trekking poles are essential; an ice axe may be needed in early season on the upper scree.
