High Country Treks
Discover Northern Arizona’s Most Unforgettable Trails

By Allison McKnight

When the desert heat in Phoenix climbs into triple digits, there’s nothing quite like heading north to Flagstaff’s forested trails, volcanic landscapes, and alpine peaks. From Arizona’s highest summit to very quiet petroglyph sites and lava fields, these trails offer the perfect escape into nature’s cool embrace. Whether you’re an experienced hiker or simply looking for a scenic stroll, here’s a closer look at some of the best trails to lace up your boots for this season.

Humphreys Peak Trail: Conquer Arizona’s Roof

Trail rating: Hard | Distance: 9.5 mi | Elevation gain: 3,000+ ft

Standing at 12,633 feet, Humphreys Peak is Arizona’s highest point and the crown jewel of the Kachina Peaks Wilderness. The rocky trail, rated difficult, climbs on and on relentlessly through alpine forest, windswept tundra, and rugged switchbacks. Summer hikers can catch glimpses of colorful wildflowers dotting the slopes, while late-season snow adds an extra challenge.

On clear days, the view from the summit stretches as far as the Grand Canyon’s rim—80 miles away. Be prepared for common afternoon thunderstorms and chilly temperatures even in July. Hiking poles, layered clothing, and extra water are essentials for this iconic Arizona adventure.

Fatmans Loop Trail: Lava, Junipers, and Views

Trail rating: Moderate | Distance: 2.5 mi | Est. time: ~1h 20m

Named for a narrow rock passage that hikers can squeeze through (or skip around), Fatmans Loop Trail is a local favorite. The path ascends gently over a historic 500,000-year-old lava flow, framed by ancient alligator junipers—some over 900 years old. Kids love climbing the scattered boulders, and the hilltop rewards hikers with panoramic views of Flagstaff and Mount Elden.

Tip: Early morning hikes offer cooler temps and fewer crowds, especially during summer weekends.

Aspen Nature Loop: Wildflowers and Open Skies

Trail rating: Moderate | Distance: 1.8 mi | Est. time: 50 minutes

Short but scenic, the Aspen Nature Loop is ideal for hikers who want big views without a big climb. The trail weaves through open meadows and groves of quaking aspen. In midsummer, the route bursts with colorful wildflowers. While relatively uncrowded on weekdays, the trail can be rocky, so wear sturdy shoes. Come winter, this path becomes part of a snowy playground near Arizona Snowbowl.

Elden Lookout Trail: Climb to the Fire Tower

Trail rating: Hard | Distance: 5.3 mi | Est. time: 4 hours

A challenging climb with a classic Flagstaff reward: sweeping views from the historic fire lookout tower atop Mount Elden. Starting in a ponderosa pine forest, the trail ascends through switchbacks, eventually opening to vistas of the San Francisco Peaks, Dry Lake Hills, and Flagstaff below. At the top, the lookout offers a striking 360-degree panorama, perfect for catching your breath and snapping photos.

Note: Start early to avoid midday heat, and bring extra water.

Walnut Canyon Island Trail: Walk Among Ancient Cliffs

Trail rating: Moderate | Distance: 0.8 mi | Est. time: 45 minutes

Step into history along the Island Trail at Walnut Canyon National Monument, where hikers can explore 25 Sinagua cliff dwellings tucked beneath limestone ledges. Over 700 years ago, a thriving Pueblo community made its home here. The short trail descends into the canyon, weaving past the ancient rooms while offering sweeping views of the rugged cliffs and forested rim.

Elevation note: Though under a mile, the climb back up can be challenging for those not acclimated to 7,000 feet.

Mars Hill Trail Loop: Shady Forest Stroll

Trail rating: Moderate | Distance: 3.3 mi | Est. time: ~1 hour 20 minutes

Close to downtown Flagstaff yet deeply peaceful, the Mars Hill Trail Loop meanders through ponderosa pines, offering shade and fresh mountain air. Wide, well-maintained paths allow for an easy-going walk or trail run. Look for distant views of snow-capped peaks and occasional mountain bikers sharing the trail. In winter, icy patches add a bit of caution but also a sparkling beauty.
