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.
Cold weather gear may be required year round for the hike along the top of the ridge. The full hike to the end of the trail is 5 KM (3 miles) return with an elevation gain of 216 m (708 ft) to a maximum elevation of 2,255 m (7,395 ft). Parker Ridge is a spectacular hike worthy of the time and effort.
