Highlights on the Trail

The summit offers sweeping views of Zion Canyon and the surrounding red-rock cliffs. The sense of exposure and accomplishment on the narrow spine, combined with the park’s dramatic scenery, makes Angel’s Landing a memorable and iconic experience.

Mist Trail to Half Dome, Yosemite National Park, USA

The hike to Half Dome via the Mist Trail is one of Yosemite’s most iconic and demanding treks. The round trip covers 14–16 miles with nearly 4,800 feet of elevation gain, and most hikers require 10 to 12 hours to reach the summit and return. The final 400 feet involve a cable-assisted climb up a near-45-degree granite face, demanding both upper-body strength and mental focus. The trail is exposed, strenuous, and physically relentless, with steep granite steps along Vernal and Nevada Falls, a sandy ascent to the subdome, and a long approach through Little Yosemite Valley.

Challenges on the Trail

Half Dome tests endurance at every stage. The Mist Trail’s steep granite steps and long ascents push legs and knees to the limit, while the subdome and cable section demand upper-body strength, balance, and nerve. Exposure on the granite face and long hours of hiking add both physical and psychological strain, and unpredictable weather can further complicate the ascent.

Difficulty Levels and Altitude

The trail gains nearly 4,800 feet over 14–16 miles, with the summit at 8,846 feet above sea level. It is one of Yosemite’s most strenuous hikes, suited only to those with high fitness, climbing experience, and tolerance for heights.
