I led this hike for the Sierra Club as a 17.5-mile loop with an accumulated elevation change of about 4,300'. We started at the Humphreys' trailhead and headed up to its saddle, then continuing on the Weatherford trail (see more photos from this hike under Weatherford) over to Freemont and Doyle saddles. After coming off the mountain on the south side, we completed the loop on the Kachina trail. This hike is quite the workout with some beautiful scenery, particularly down into the Inner Basin. We ended splitting into two groups, with the first group completing the trek at a fast pace in 7.5 hours and the latter at a moderate pace in about 10.5 hours.
