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.
Where to start the hike to Yosemite's Half Dome: 1. Happy Isles at the Vernal Fall trail head. The Mist Trail to Vernal Fall then to Nevada Fall (steep and rigorous). Or the John Muir Trail (horse trail) to Nevada Fall (easier, longer and dustier) with horse droppings along the way.
