Historical Background of Half Dome in Yosemite National Park

  • Distinct crescent shape created from geological processes.
  • Surrounded by lush valleys, meadows, and other granite formations.

Routes to Half Dome

The journey to Half Dome in Yosemite offers hikers two primary routes:

Mist Trail 

This is the more direct route, covering about 14 to 16 miles round-trip, depending on the exact trailhead start. The trail begins in Yosemite Valley near the Happy Isles Nature Center. Mist Trail is aptly named, as it leads hikers up a set of steep granite stairs right past Vernal and Nevada Falls. Especially during the spring and early summer, the mist from the waterfalls can drench hikers, hence the name. This route is not only steeper but also offers some of the most iconic views in Yosemite. After Nevada Fall, the Mist Trail joins the John Muir Trail leading to Half Dome.

John Muir Trail (JMT)

Slightly longer, this trail is considered a bit easier on the knees because it doesn’t have the steep stair sections that Mist Trail does. The JMT also begins in Yosemite Valley and intersects with the Mist Trail at several points. Hikers on this trail will also enjoy views of Vernal and Nevada Falls, but from a different perspective. After the top of Nevada Fall, the trail continues through the Little Yosemite Valley and then starts its ascent towards Half Dome.

Hiking to Half Dome

Starting at the Yosemite Valley Trailhead, the path meanders towards the first significant viewpoint, the Vernal Fall Footbridge. From here, the Vernal Fall cascades down in its full might, a sight that especially thrills first-time visitors. As hikers progress upwards on the Mist Trail, the journey becomes damp and cool, courtesy of the waterfall’s mist. This climb offers an intimate experience with the Vernal Fall, with the sound of rushing waters providing a rhythmic backdrop.

The next phase of the journey leads to the majestic Nevada Fall. The view from here is panoramic, with Liberty Cap’s granite peak in the foreground and the backcountry wilderness in the distance. The Nevada Fall viewpoint also serves as a popular rest stop where hikers can rejuvenate and refuel.

Post these waterfall encounters, the trail opens into the Little Yosemite Valley. This flat expanse is a stark contrast to the uphill climbs and offers a serene meadow, perfect for a breather and some picturesque photography. It’s not uncommon to spot deer or other wildlife here.

The Subdome is the final challenge before reaching Half Dome. While it might seem dwarfed by the Dome itself, the ascent is rigorous. However, the reward is immense, with wide-ranging views of Yosemite unfolding as one climbs. Upon reaching the base of Half Dome, hikers are faced with the famed cables. The effort of the ascent is immediately forgotten once the summit is reached. From here, the entirety of Yosemite National Park stretches in all directions, making the arduous journey worth every step.

The area around Half Dome, with its varied habitats, ensures that every birdwatching session is filled with exciting discoveries.

Half Dome Cables

The Half Dome cables are an essential part of the ascent to the dome’s summit. Spanning the last 400 feet of the hike, these cables are set up during the warmer months and taken down in winter to prevent damage from snow and ice. They are affixed to steel posts, with wooden planks placed approximately every 10 to 15 feet, aiding hikers in their steep climb. The very existence of these cables makes the ascent possible for many, as they provide the much-needed grip and guidance on the dome’s sheer granite face. The experience of ascending with the assistance of these cables, with the vast expanse of Yosemite spread below, is both thrilling and humbling.

Safety During the Hike Using Cables: 

  • Gloves are essential for better grip on the cables.
  • Avoid hiking during rain or thunderstorms as wet granite is slippery, and the area is prone to lightning.
  • Always yield to descending hikers. 
  • Don’t try to bypass others by going outside the designated path.
  • Take your time.
  • Stay hydrated and take breaks as needed.
