<P> The Half Dome Cable Route hike runs from the valley floor to the top of the dome in 8.2 mi ( 13 km ) ( via the Mist Trail ) , with 4,800 ft ( 1,460 m ) of elevation gain . The length and difficulty of the trail used to keep it less crowded than other park trails , but in recent years the trail traffic has grown to as many as 800 people a day . The hike can be done from the valley floor in a single long day , but many people break it up by camping overnight in Little Yosemite Valley . The trail climbs past Vernal and Nevada Falls , then continues into Little Yosemite Valley , then north to the base of the northeast ridge of Half Dome itself . </P>
