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.
If you want to cut your mileage down on the day you climb Half Dome, spend the night in the Little Yosemite Valley campground, a mile beyond the top of Nevada Fall. This way you won't have to climb the Mist Trail the morning of your hike - a savings of about 4 miles (6.5 km) one way. You'll be a couple hours ahead of the midday hordes of Half Dome hikers, and you'll get to the cables before it gets too crowded.
