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.
Every summer park rangers must assist hundreds of people on the Half Dome trail. The most famous--or infamous--part of the hike is the ascent up the cables. The two metal cables allow hikers to climb the last 400 feet to the summit without rock climbing equipment. Since 1919, relatively few people have fallen and died on the cables. However, injuries are not uncommon for those acting irresponsibly.
