We took a group of 13 hikers for an excursion to the top of Nevada Falls from the valley floor of Yosemite. This hike is about eight miles long round trip from the trailhead parking lot. We hiked up the Mist Trail along the Vernal Falls and on the way back, we took the longer John Muir Trail which is less taxing on the knees and toes. The total hiking time is 8 hours including way too many breaks. Elevation gain is 2000 feet.
