Date: May 22, 2012

The cables allowing access for hikers to the summit of Half Dome in Yosemite National Park will be in place and open for the season on Friday, May 25, 2012, weather permitting.

Visitors are required to have a permit to ascend the Half Dome cables seven days per week. The majority of the permits were distributed through a lottery system that ended in March. However, approximately 50 permits per day are available through a two day in advance lottery. Visitors without a Half Dome permit wishing to hike the cables may enter the lottery two days in advance of their planned day hike by visiting www.recreation.gov or by calling 1-877-444-6777. For more information regarding the lottery and the Half Dome cables, please visit www.nps.gov/yose/planyourvisit/halfdome.htm.  

The trail to Half Dome from Yosemite Valley is an extremely strenuous hike covering over 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 forecasted and are advised to use extreme caution when the rocks are wet.

Rockfall events have helped shape many of the outstanding features along Yosemite Valley's walls, including Royal Arches, North Dome, and Half Dome. Giant talus slopes that slant away from the Valley walls accumulate debris with each rockfall event.
