Rising nearly 5,000 feet above Yosemite Valley and 8,800 feet above sea level, Half Dome is a Yosemite icon and a great challenge to many hikers. Despite an 1865 report declaring that it was "perfectly inaccessible, being probably the only one of the prominent points about the Yosemite which never has been, and never will be, trodden by human foot," George Anderson reached the summit in 1875, in the process laying the predecessor to today's cable route.

Today, thousands of people reach the summit each year without incident, however the 14- to 16-mile round-trip hike to Half Dome is not for you if you're out of shape or unprepared. You will be gaining elevation (for a total of 4,800 feet) most of your way to the top of Half Dome. Most would say the reward is worth the effort. Along the way, you'll see outstanding views of Vernal and Nevada Falls, Liberty Cap, Half Dome, and from the shoulder and summit there are panoramic views of Yosemite Valley and the High Sierra.

Most hikers average 10 to 12 hours to hike to Half Dome and back. If you plan on hiking during the day, it's smart to leave around sunrise (or earlier) and then have a non-negotiable turn-around time. For instance, if you haven't reached the top of Half Dome by 3:30 pm, you will turn around. Check for sunrise and sunset times before you hike. Regardless, each person should carry a flashlight or headlamp with good batteries. Although the trail is well marked, you should be prepared with a good topographic map and compass and know how to use them. The most famous, or infamous part of the hike is the ascent up the cables. The two metal cables allow hikers to climb the last 400 feet to the summit without rock climbing equipment. This is definitely an adventure worth taking, but not taking lightly.

A permit is required to hike to Half Dome seven days per week. The permit system has changed this year to help limit numbers and preserve the trail condition. More information on the hike and necessary safety precautions can be found on the National Park Service website.
