Permits to Ascend Cables will be Required Seven Days Per Week

Yosemite National Park announces that Day Use Permits to climb the Half Dome cables will be required seven days per week for the 2011 summer season to increase visitor safety on the cables.

Over the past several years, the popularity of the hike has resulted in large numbers of people using the Half Dome cables, particularly on weekends and holidays. Saturdays and holidays averaged 840 visitors per day, while peak days saw up to 1200 people using the cables. These large numbers of hikers generated significant safety concerns and there was a fatality and serious injuries sustained by park visitors due to these crowded conditions.

The park instituted an interim program for climbing the Half Dome cables in 2010 to address these serious safety concerns. Day Use Permits were required to use the cables on Fridays, Saturdays, Sundays, and holidays during the 2010 season. Although the interim program worked well on the permit days, visitor use on the cables during days in which permits were not required reached peak weekend levels, analogous to peak days before permits were required.

Therefore, to address the consistent crowded conditions on the Half Dome cables, Day Use Permits will be required seven days per week for the 2011 summer season. The Half Dome cables are generally in place from mid-May through mid-October, depending on snowpack and weather conditions.

The Half Dome Day Use Permits will be available starting March 1, 2011 for climbing the cables in May and June, 2011. Subsequent permits will be available at the beginning of each month for permits three months in advance. Reservations for a permit can be made through www.recreation.gov or by calling 1-877-444-6777. Each person climbing the Half Dome cables will be required to have their own permit. Up to four permits may be obtained under one reservation. The permits are free, however, there is a non-refundable $1.50 service charge for each permit obtained.

During this interim program, visitor use and impacts are being monitored. Yosemite National Park Rangers are studying visitor use and safety, assessing the visitor experience, and compiling data that will be analyzed by park managers. An Environmental Assessment process for a long-term plan for the Half Dome cables began public scoping in spring 2010.

Vernal and Nevada Falls

In Yosemite Valley, dropping over 594-foot Nevada Fall and then 317-foot Vernal Fall, the Merced River creates what is known as the “Giant Staircase.” Such exemplary stair-step river morphology is characterized by a large variability in river movement and flow, from quiet pools to the dramatic drops of the waterfalls themselves.
