Warning, weekend hikers: If you’re planning an assault on Half Dome in May or June, your time has just about run out.
In their first 48 hours of peddling hiker permits, under a new system designed to relieve weekend and holiday crowding on Yosemite National Park’s popular Half Dome Trail, park concessionaires have sold nearly all of the 5,700 available

Climbing Yosemite’s Half Dome requires strength, stamina and a whole lot of bravery.

Come May, it will require a day-use permit.

With growing concerns about over-crowding and safety on one of the park’s most famous slabs of granite, park officials announced this morning an “interim” two-year plan that will place a cap on the number of climbers on Fridays, Saturdays, Sundays, and holidays.
