The cables allowing access for hikers to the summit of Half Dome will be in place for the season on Wednesday, Yosemite National Park officials said.
Visitors to Half Dome's summit on Fridays, Saturdays, Sundays and holidays are required to get a permit. Most permits for 2010 have been reserved already, but for information, visit http://www.recreation.gov. No permits are required Mondays through Thursdays. Visitors hiking the trail leading up to the base of Half Dome cables don't need a permit.
The trail to Half Dome from Yosemite Valley is a 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.
