Half Dome Elevation: 8,842 feet (2,695 meters) Total Elevation Gain: 4,800 feet (1,600 meters) from Yosemite Valley. The red line marks the route of the Mist Trail, which will take you (if only! actually, you'll take it) to the top of Nevada Fall. This stretch is 2.6 miles (4.2 km) long and climbs 2,000 feet (600 meters). It's the most scenic stretch of the trail until you approach the shoulder of Half Dome.
One can't talk about the beauty of Yosemite without talking about Half Dome, the white whale of rock hikes that when first viewed by American settlers was deemed unclimbable. This giant towers 5,000ft over the Yosemite Valley, the most famous and visible peak in the park. Thousands of climbers every year brave the 10-to-12-hour hike to the summit, the last 400ft of which requires metal cables.
