Hiking to Half Dome via the Cables in Yosemite Valley

Hiking to Half Dome via the Cables is one of Yosemite Valley's most thrilling and iconic outdoor experiences. This challenging 14- to 16-mile round-trip hike ascends over 4,800 feet, offering panoramic views and an unforgettable finale: a steep climb up the cable route to the summit of Half Dome. This once-in-a-lifetime adventure draws visitors for its combination of physical challenge and breathtaking scenery, making it one of the most sought-after activities in Yosemite. Due to its popularity and safety concerns, a permit system is in place to regulate access.

Adventure Guide to Hiking to Half Dome via the Cables

• Trailhead and Route: Begin your journey at Happy Isles in Yosemite Valley, following the Mist Trail or John Muir Trail to Vernal and Nevada Falls. The Mist Trail features stone staircases and close-up views of cascading waterfalls, while the John Muir Trail provides a longer but less strenuous ascent. The hike culminates with the Sub Dome's steep granite switchbacks, leading to the cables section.

• The Cables Section: The summit push involves ascending a sheer 400-foot granite slope using metal cables bolted into the rock. This section is not for the faint of heart, requiring upper body strength, sturdy footwear, and careful pacing to manage fatigue. Gloves are highly recommended for gripping the cables.

• Half Dome Summit: At the 8,836-foot summit, hikers are rewarded with unparalleled views of Yosemite Valley, El Capitan, and the High Sierra peaks. The flat granite summit provides ample space to rest, take photos, and soak in the unique vantage point.

Local Insights

The cables system was installed in 1919 to assist hikers with the final ascent. While thrilling, this section can be dangerous during wet weather due to slick granite. Yosemite suggests attempting the hike between late May and early October when the cables are upright. Avoid visiting after storms to ensure safety.
