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.
Permits are required to hike up Half Dome, and you can't show up and get them at the park. Each day 300 are issued: 225 to day hikers and 75 to backpackers. Hikers use the cables to complete the 14- to 16-hour day hike to the roughly 8,800-foot summit. (Check out Yosemite's hiking page for more details). Here's how to apply for an early permit: Enter the lottery two days before you plan to go. (So if you want to hike on Saturday, you would apply Thursday).
