Flagstaff sits at 7,000 feet in the largest ponderosa pine forest on Earth. That means cooler temps than the Valley (20–30°F cooler in summer), actual seasons, and trail access that ranges from flat riverside strolls to a 12,633-foot summit push. Whether you just want to stretch your legs after the drive from Phoenix or you're training for something serious, there's a trail here for you.
All of these trails are on Coconino National Forest land or within national monuments. I've hiked all of them and listed them from easiest to hardest. Distances are round-trip unless noted.
Easy Hikes (Beginner-Friendly)
1. Fatman's Loop — 2.4 miles, 400 ft gain
The classic Flagstaff warm-up. The trail squeezes through a narrow slot in the volcanic rock (hence the name) and loops through ponderosa pines with views of Mount Elden. Park at the Elden Trailhead on Highway 89 — free parking, no permit needed.
Best for: First-timers, families, altitude acclimatization Time: 1–1.5 hours2. Lava River Cave — 1 mile (out and back)
More of an exploration than a hike, but worth every minute. This mile-long lava tube is pitch black inside, 35°F year-round, and completely free. Bring two flashlights per person (seriously — if one dies, you're in total darkness). Located 14 miles west of Flagstaff off Highway 180.
Best for: Kids, geology buffs, hot summer days Time: 45 minutes to 1.5 hours depending on how far you go3. Buffalo Park Loop — 2 miles, minimal elevation
A gentle loop through an open meadow with panoramic views of the San Francisco Peaks. Wide gravel path, dog-friendly, and popular with joggers. The trailhead is on Cedar Avenue — one of the few trails you can reach without a car if you're staying downtown.
Best for: Morning walks, dog owners, stroller-friendly Time: 45 minutesIf you're looking for more easy options, check out our full outdoor adventures guide for Flagstaff which covers trail systems across the whole region.
Moderate Hikes
4. Kachina Trail — 5 miles one-way, ~700 ft change
This point-to-point trail (about 10 miles round-trip, or a shorter out-and-back) traverses the south face of the San Francisco Peaks through aspen groves that turn electric gold in October. One of the best fall foliage hikes in Arizona. Start from the Arizona Snowbowl parking area at 9,500 feet.
Best for: Fall foliage, wildflowers (July), long-distance hikers Time: 4–5 hours (full traverse with shuttle)5. Walnut Canyon Rim Trail + Island Trail — 2 miles combined, 185 ft gain
Two short trails at Walnut Canyon National Monument, 10 miles east of town. The Island Trail descends 185 feet into the canyon past 25 cliff dwelling rooms built by the Sinagua people around 1100 AD. You walk inside 900-year-old homes carved into limestone. Entry is $25 per vehicle (7-day pass). Open 9 AM–5 PM.
Best for: History lovers, families, photography Time: 1.5–2 hours for both trails6. Sunset Crater Lava Flow Trail — 1 mile, flat
A loop through the lava fields of Sunset Crater Volcano National Monument, 15 miles northeast of Flagstaff. The trail crosses jet-black volcanic rock and cinder fields — it looks like another planet. Combine with Wupatki National Monument for a full day. Same $25 vehicle pass covers both parks.
Best for: Geology, photography, unique landscapes Time: 30–45 minutesGuided Hiking Tours in Flagstaff

Hard Hikes (Experienced Hikers)
7. Humphreys Peak — 9.5 miles, 3,333 ft gain
Arizona's highest point at 12,633 feet. The Humphreys Peak trail starts from the Arizona Snowbowl parking lot at 9,300 feet and climbs through spruce-fir forest, then above treeline into alpine tundra. The summit views are staggering — on clear days you can see the Grand Canyon rim and the Painted Desert.
Critical safety: Start at sunrise. Afternoon lightning storms above treeline are dangerous and common from July through September. Bring layers — it can be 40°F colder at the summit than in town. Snow-free window is typically mid-June through mid-October. Best for: Peak baggers, bucket-list hikers Time: 6–8 hours8. Mount Elden Lookout — 6 miles, 2,400 ft gain
A relentless climb up the Elden Lookout Trail to the fire tower at 9,299 feet. The payoff is a 360-degree view of Flagstaff, the San Francisco Peaks, and Oak Creek Canyon. Steeper than Humphreys but lower elevation, so the air is more forgiving.
Best for: Strong hikers who want views without the Humphreys commitment Time: 4–5 hours9. Inner Basin Trail — 8 miles, 2,000 ft gain
Follows an old pipeline road into the heart of the San Francisco Peaks volcanic caldera. Wildflower meadows in summer, aspen gold in fall, and a feeling of total isolation despite being 15 minutes from downtown. Start from Lockett Meadow (Forest Road 552 — high-clearance vehicle recommended).
Best for: Solitude seekers, wildflower season, fall color Time: 4–5 hours10. Arizona Trail: Flagstaff Passage — 31 miles (thru-hike)
Flagstaff's section of the 800-mile Arizona Trail runs from Walnut Canyon to the base of the San Francisco Peaks. Most people break this into 2–3 day segments or cherry-pick sections. The segment through Marshall Lake to Fisher Point is the most scenic day-hike option (12 miles).
Best for: Backpackers, trail runners, long-distance hikers Time: 1–3 daysTrail Tips for Flagstaff
Altitude matters. If you're coming from sea level or Phoenix (1,100 ft), give yourself a day to adjust before tackling anything above moderate. Drink more water than you think you need. Monsoon season (July–August): Mornings are clear, afternoons bring thunderstorms. Start early and plan to be off exposed ridgelines by noon. Parking: Most trailheads are free. Snowbowl lots fill by 8 AM on summer weekends. Walnut Canyon and Sunset Crater require a park pass. Dogs: Allowed on Coconino National Forest trails (leash required). Not allowed in national monuments (Walnut Canyon, Sunset Crater, Wupatki). Trail conditions: Check AllTrails for recent trail reports and current conditions before heading out.For equipment rentals and guided trips, several outfitters in downtown Flagstaff offer gear and guided hiking tours. Peace Surplus on Route 66 is the local go-to for last-minute gear.

Frequently Asked Questions
What is the best easy hike in Flagstaff?
Fatman's Loop (2.4 miles) is the best beginner hike. It's close to town, free, and gives you a taste of Flagstaff's volcanic terrain and ponderosa forest. Buffalo Park is even easier if you need a flat, paved option.
Can you hike Humphreys Peak in winter?
Technically yes with snowshoes or crampons, but it's an advanced winter mountaineering route with avalanche risk. Most hikers stick to the June–October snow-free window. Skiing at Arizona Snowbowl is a better winter option on the same mountain.
Are there good hikes near downtown Flagstaff?
Yes. Buffalo Park is a 5-minute drive from downtown. The Flagstaff Urban Trail System connects downtown to Thorpe Park, the Northern Arizona University campus, and several trailheads without needing a car.
Do I need a permit to hike in Flagstaff?
No permits for Coconino National Forest trails (most hikes on this list). National monuments (Walnut Canyon, Sunset Crater) require a $25 vehicle entry pass. No wilderness permits required for day hikes.
When is the best time to hike in Flagstaff?
May through October for the full trail selection. September and October offer the best weather — warm days, cool nights, no monsoon storms, and fall color starting mid-October. Summer (June–August) is popular but expect afternoon thunderstorms.
