NOTE: I plan to add a hike in Flagstaff on Saturday Sept. 28 (the day before this hike); so many of us will plan to spend the weekend in Flagstaff.

This awesome hike is the long way up to Humphreys Peak -- it's 17 miles with an AEG of 4,600' as compared to 10.5 miles and an AEG of 3,300' by going up via the Snow Bowl. The reward for doing the hike in this manner is some awesome scenery, including an amazing grove of aspen trees in the Inner Basin, which should be at the peak of their autumn splendor!

This may be one of the last times in the fall that we'll be able to hike up to Humphreys Peak without snow on the ground. Even so, expect some cold temperatures atop Humphreys.

This hike will begin and end at the Inner Basin Trailhead, which is near the Lockett Meadow Campground. We'll be on the Inner Basin Trail for almost 4 miles, and then we'll turn right on the Weatherford Trail. We'll take the Weatherford Trail to the Humphreys Summit Trail, and from there we'll go up to Humphreys Peak.

This hike is challenging enough due to distance and elevation gain, but the high altitude makes it even more challenging, especially as you get over 11,000 feet -- 6-7 miles of this hike are at an altitude over 11,000 feet. Altitude sickness can be an issue, so it is best to plan for your pace being slowed by the altitude. Be sure to hydrate well the day before as well as the day of the hike.

Due to the nature of this hike participation will be limited to people whose hiking abilities are known to me. If you would like to participate in the hike, please join the waiting list and I will add you to the hike as appropriate.
