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.
At around mile six, turn left, leaving John Muir Trail for Half Dome. This is near Little Yosemite Valley Trail Camp. Turn north through tall conifers to reach the base of the sub dome below Half Dome. From here (about 8,000 feet), you get a unique side view the daunting dome.
