About Humphreys Trail

Humphreys Trail is an out-and-back trek that takes you to the highest natural point in Arizona, above 12,000 ft. The trail is full of lush alpine forests and mountainous scree fields. Hikers will witness some of the state’s most magnificent views.

Mt. Humphreys, along with Mt. Agassiz and Mt. Fremont, are within Arizona’s San Francisco Peaks. A mountain range located right outside of Flagstaff, Arizona. 

This range is believed to have reached an elevation of 16,000 feet, right before a volcanic eruption that occurred more than 1,000 years ago.

As one of the more difficult trails in Arizona, Humphreys Trail isn't for first-time hikers. Overall, the trail itself is very steep and can be very rocky at times, with an elevation increase of 3,000 ft.

This makes the journey challenging. That's not to say that new hikers can't submit the top, but hikers will need to persevere.

How to Get to the Humphreys Trailhead

The Humphreys Trail trailhead is in the Arizona Snowbowl ski resort, north of Flagstaff.

You can access the trailhead lot, Hart Prairie, from Hwy 180. If you are heading in from Flagstaff, drive North on Humphreys St. and turn left onto Hwy 180. You can also type in Hart Prairie Lot into your GPS.


Humphreys Trail Guide

This is an extensive hike, so be sure to start early to ensure enough time to make it to the summit and back before dark. To start, you will pass under a ski chairlift. Then continue through a meadow full of wildflowers and high grass.

The trail will take a slight left, and you will enter a thick forest with pine trees, aspens, firs, and spruce trees. You will continue to follow the trail through steep and lengthy switchbacks. This will seem like the longest part of the hike.

This trail is well marked with directional wooden signs.

As you approach the 3.75-mile marker, the tree line will begin to thin. You may even notice the air thinning as well– this may make it more difficult to catch your breath. Be prepared for a temperature decrease as you gain elevation.

You will soon reach the saddle between Agassiz Peak and Humphreys Peak. Take a left to continue to Humphrey’s summit. The Weatherford Trail veers right towards Agassiz.

At the saddle, be alert to the weather as you are above the tree lines, and the route is no longer covered. Thus you will not be protected and will be exposed to the elements. During the winter season, expect ice and snow on the trail.

The trail will zigzag through rocky terrain and large boulders. The footpath remains visible, and the wooden stakes will continue to guide you. 

The final mile is strenuous and has a few false summits. Keep hiking. You will know when you made it to the top when you see the legendary sign with the elevation, 12,633 ft.

Rest, regroup, and take in the 360-degree views!!! On a clear day, you can see the Grand Canyon to the north, and the Mogollon Rim to the south.

Once you have had your fill of the incredible panorama views, head back down the same way you came up.


What to Pack For Hiking Humphreys Trail 

Below is an example of essential day-hiking gear for Humphreys Peak in September.

*Headlamps on day hikes are for those emergency moments. All it takes is a wrong turn or the trek taking longer than anticipated, and hikers are walking back in the dark. A headlamp to light the path back to the trailhead is a crucial benediction. Packing extra batteries is a bonus.

NOTE: What you pack in, you must pack out.  As always, do not leave any trace of snacks or drinks on the trail.

What You Need To Know Before Hiking Humphreys Trail

Elevation

Be mindful that the trail begins at 9,200 ft. in elevation and rising to over 12,500 feet. The air will get thinner, which leaves hikers at risk of altitude sickness.

If you incur altitude sickness, we recommend rest, rehydrate, and descend back down. DO NOT proceed to the summit if you are feeling dizzy, light-headed, or nauseous.

Storms 

Always check the weather before any hike!

When at the saddle between Agassiz Peak and Humphreys Peak, be alert to any changing weather. As the route after the saddle is no longer covered and you are above the tree line. When storms are brewing toward the San Francisco Mountains, Humphreys Trail is at high risk for avalanches.

During the monsoon season (July to September), lightning rainstorms can blow in fast. Be prepared to head back to lower ground if a storm is in the distance.

For current weather, visit National Weather Service. For more information on avalanches, visit the Kachina Peaks Avalanche Center Snowpack Report.

Wind

As hikers proceed towards the summit, prepare for aggressive gusts of wind. Bring a jacket or thicker layer to cover up with at the top. You will thank yourself later!
