Date: May 21, 2007

The cables allowing trail access to hikers to the summit of Half Dome were put in place on May 17, 2007.

The Half Dome hike is a round-trip hike of over 17 miles and is considered extremely strenuous. Hikers gain 4,800 feet of elevation along the hike that passes highlights such as Vernal Fall, Nevada Fall, and Half Dome itself. A series of metal cables 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 lightening are common occurrences in the High Sierra during the summer and fall; hikers should not to attempt to summit Half Dome around or during thunderstorms and are advised to use extreme caution when the rocks are wet.

Sierra Sweet Bay

In Wawona and downstream, the South Fork Merced River provides habitat for a rare plant, the Sierra sweet bay (Myrica hartwegii). This special status shrub is found in only five Sierra Nevada counties. In Yosemite, it occurs exclusively on sand bars and river banks along the South Fork Merced River downstream from Wawona and on Big Creek.
