The Half Dome Cable Hike will take hikers about 10 – 12 hours to complete, there and back, depending on skill level and weather. Undertakers of this trail will be rewarded with views of Vernal Fall, Nevada Fall, Liberty Cap, and of course, Half Dome. Once you reach the subdome and summit, you will be blown away by the magnitude and panoramic views of both the Yosemite Valley and the High Sierra.
