Inner Basin Trailhead

Inner Basin Trailhead sits inside the San Francisco Peaks, about 80 miles south of the South Rim, and it's the trail Flagstaff locals point out-of-towners toward every autumn. The route climbs through Lockett Meadow into a bowl of aspens ringed by the Peaks' old volcanic rim, and when the leaves turn in late September and early October, it's one of the most reliable fall-color hikes in Arizona.

What to expect

Reviewers consistently flag it as an easy, well-graded trail — about 10 miles round trip with a steady but manageable incline — though the approach eats more time than people expect. Multiple recent reviews note the drive up the forest road from the parking area can take 1 to 1.5 hours on its own, and on busy fall weekends the gates may close, adding a few extra miles on foot just to reach the trailhead. A midsize SUV without four-wheel drive has been enough for some visitors, but the road is rough and conditions vary by season.

Bring the whole day, not just the hike — between the access road and the walk itself, this is more of a half-day-plus outing than a quick stop.
