The trail to Half Dome from Yosemite Valley is an extremely strenuous hike covering more than 17 miles.

Hikers gain 4,800 feet of elevation along the trail that passes highlights such as Vernal Fall and Nevada Fall, before reaching the cables on Half Dome’s steep granite shoulder.

Metal cables and wooden planks are placed along the steep shoulder of the dome to assist hikers to the summit.

Visitors are advised to take appropriate precautions when planning a hike of this length and difficulty, and to be prepared for changing weather and trail conditions.

Thunder and lightning are common occurrences in the High Sierra during the summer and fall seasons.

Hikers should not attempt to summit Half Dome when rain or thunderstorms are forecast, and are advised to use extreme caution when the rocks are wet.
