Half Dome is Yosemite National Park's most recognizable granite monolith, drawing hikers and climbers with its sheer cliffs, panoramic Sierra Nevada views, and storied wilderness character.
Half Dome has shaped the identity of Yosemite National Park since the park's earliest days. John Muir wrote about it with reverence, and George Anderson became the first person to reach its summit in 1875 by drilling iron bolts into the granite, a feat that foreshadowed the permanent cable route installed decades later. The dome's distinctive profile, sliced cleanly as if by a geologic blade, is the result of glacial action and exfoliation over millions of years rather than any single dramatic event.
The standard route to Half Dome follows the Mist Trail past Vernal Fall and Nevada Fall before ascending through the Sub Dome and onto the cables. That final 400-foot push up a 45-degree granite slope is the section that defines the hike for most visitors. At the broad, relatively flat summit, you stand at roughly 8,800 feet with unobstructed views of Tenaya Canyon, the Clark Range, and the vast expanse of the Yosemite high country stretching in every direction.
The surrounding valley offers its own relationship with Half Dome. From Sentinel Bridge at midday, the dome reflects in the Merced River in one of the most photographed scenes in any national park. Valley Loop trails and meadow viewpoints give those who prefer a gentler experience an intimate sense of the formation's scale without a single switchback.
Half Dome is a place where geology, history, and physical challenge converge in a landscape of genuine grandeur, making it a destination that leaves a lasting impression on nearly everyone who encounters it.
Obtain a Half Dome wilderness permit well in advance, as the daily quota fills quickly and permits are required for the cable section during peak season.
Start your hike no later than sunrise to avoid afternoon thunderstorms, which build rapidly over the Sierra Nevada and can make the exposed cables dangerous.
Bring a pair of work gloves for the final cable section, where the steel cables and wooden footrests demand a firm grip on steep, polished granite.
Carry at least three liters of water per person and pack high-calorie snacks, as the round trip from Yosemite Valley covers roughly 14 to 16 miles with significant elevation gain.
Pause at Glacier Point Road overlooks on your way out of the park for a classic full-profile view of Half Dome glowing in the late afternoon light.
