  • Half Dome is a famous granite dome in Yosemite National Park at the eastern end of Yosemite Valley -- possibly Yosemite's most familiar sight.
  • The granite crest rises more than 4,737 ft above the valley floor.
  • Thousands of hikers reach the broad flat top of Half Dome each year by following an 8.5 mile trail from the valley floor. The trail climbs past Vernal and Nevada Falls and then with the aid of a pair of steel cables ascends the final pitch up the peak's steep granite east face.
  • In past years, as many as 1,000 hikers per day have sometimes climbed the cable route on a summer weekend and about 50,000 hikers climb it every year.
  • In January, 2010, the National Park Service announced that permits will be required to hike the cable route on Fridays, Saturdays, Sundays and federal holidays. The park service cited safety concerns and increased crowding on the route as reasons for the new regulations.
"Left 5AM with a group of 11 hikers. Reached the base of Half Dome around 12 noon. Climbed the cables to the top. Was on top of Half Dome for ~ 10 minutes when thunderclouds appeared and coaxed us down. Still worth it." - wim-de-groot, Sep 4, 2018
"Another go at Half Dome as part of a southbound JMT. Climbing by sunrise and had the mountain practically to ourselves this time. Really hoping to Snake Dyke this one next time." - JustinB, Jul 24, 2018
"California. Came from Tenaya Lake and passed Clouds Rest. We did not have permit but got very lucky. A group of 5 russians from LA had a regular permit for 6, one of their friends got way behind and they did not want to wait for her. We both could accompany them. :-) Cables were steeper than I thought! Squirrels at the top. Foggy because of forest fires." - Pieter, Aug 27, 2017
"Climbed the 5.7 R pitch up snake dike then the 1000 ft scramble to the top with Nate Kemp and ClimberSteve. Went down the cables that are currently down with a via ferrata style setup then took the long 12 or so mile hike back to the valley. Started 3:15 am finished in time for beer at the valley 9:50pm" - wmitchell, May 19, 2017
"A hike as designed by Walt Disney. Too much beauty to take in and way to much to describe here. Hit the trail by headlamp at 5:30 on a weekday and I was not alone by any means. Worth it as the scariest thing on the cables are the other people. Cannot wait to do it again." - JustinB, Sep 20, 2016
