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.
Mary ForgioneDaily Deal and Travel Blogger. The hike to the top of Half Dome in Yosemite National Park includes a harrowing scramble up metal cables to complete the last 400 feet to the summit. Day hikers are required to have permits to use the cables, and the preseason lottery for permits is open now through March 31. Before you apply, make sure you're in shape for this 17-mile round-trip journey from Happy Isles in Yosemite Valley to the top of the 8,842-foot rock face.
