Humphrey's Peak via Inner Basin Trail

The Lockett Meadow Inner Basin is renowned for its gorgeous views, making it a perfect starting point for your adventure up the tallest mountain in Arizona, Humphrey’s Peak. This route leads you through a beautiful aspen forest, then up, up, and up to the top. You should be comfortable acclimatized to Flagstaff’s elevation before attempting this climb. Hikers should bring lots of water to avoid symptoms of altitude sickness. Bring lots of warm layers for the often-chilly summit.

The trailhead for this hike is at the very back of the day-use parking area. You’ll start by hiking through a mature pine forest. The pine trees give way to aspens. Begin a set of switchbacks towards the inner basin. This part of the hike follows a dirt road, and you’ll soon turn right onto a service road that leads you into the basin. At the signed fork, continue along the basin trail.

In the basin, continue to Doyle Spring Trail. You’ll hike west across the east face of Agassiz Peak to find the Humphrey’s Peak Trail (you’ll meet up with hikers here who started on the Snow Bowl side). Hike north along the ridgeline in your final push to the top. From here, retrace your steps.
