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.

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.

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.

Secure a Half Dome permit in advance through Yosemite’s lottery system.

Bring 4+ liters of water, high-calorie snacks, gloves, a first-aid kit, and a headlamp for early starts or late returns.

From Yosemite Valley, the Happy Isles trailhead is a 10-minute drive or shuttle ride.
