This description is misleading. We decided to do the hike the opposite direction, starting at Thomas Creek Trailhead. The elevation gain was nearly 5000’. Apparently All Trails doesn’t count decent as part of their elevation figures. The mileage is off as well. It’s over 20 miles long. We also threw in the section up to the top of Mt. Rose for a total elevation gain of 6000’ and total distance of 23 miles. The elevation gain is pretty gradual. Views of the Mt. Rose backcountry are amazing.
