It is famous worldwide as a World Heritage Site and for its dramatic geologic formations. Within these granite rocks and cliffs, numerous waterfalls flow year-round and massive ancient sequoia trees shield the valleys.
The most common way to begin your adventure to the Half Dome is via The Mist Trail. There are other alternative ascent trail options, such as Glacier Point or via Tenaya Lake. The Mist Trail is 14.2 miles round trip, making this route the shortest and most scenic. Most hikers take 10-12 hours to complete this. The best time to visit the Half Dome is anytime from late May to October.
The Half Dome is by no means a walk in the park. Half Dome is a 14-mile round trip hike with an elevation gain of 4,800ft. This is one of the longest and steepest day hikes in Yosemite. In 1865, it was reported to be inaccessible.
Those who are experienced climbers will take on the challenge of climbing on the Northwest face of the Half Dome, making this a U.S. first Grade VI climb. Hiking to the Half Dome via the Mist Trail is a less daunting option but still requires you to be physically fit and have previous hiking experience. There is a mountaineering component at the end with cables leading you to the top of Half Dome.
Your journey will begin near the Happy Isles Bridge that crosses the Merced River. Due to the Half Dome’s famous reputation, the trails can get crowded.
To prevent this, the park has required everyone to obtain a permit. This permit allows you to access the cable route that gets you to the top of the Half Dome. You must apply for this permit in advance. They are awarded on a lottery basis beginning in March. You can apply for this permit online or by phone and it costs $10.
On the Mist Trail, you will climb hundreds of steps right beside Vernal Falls. It is crucial you take caution in this area, as the steps will be wet and slippery. Once you reach the top, you will hike beside Nevada Falls. Once you’ve surpassed the falls, there will be a decent length of flat ground through Little Yosemite Valley. After hiking through more forest-area, you will reach the sub dome.
This is what will lead you to the cables. The sub dome steps are at 8,000 ft. The cables are up from late May to early October. One thing to note is that the cable section is not for those who are afraid of heights. You are completely exposed and walking up vertically. Once you have reached the top of the cables, you are faced with spectacular views of the iconic vistas of Yosemite.
The Half Dome is found east of Yosemite Valley. If you are using the Mist Trail, your journey will begin near Curry Village.
This 14-mile day hike begins on the Mist Trail, to the top of Vernal and Nevada Falls, through Little Yosemite Valley, up to the Sub Dome, and to the cable route where you will reach the top of the Half Dome.
