Iconic. Rarefied. Supersonic. There are not enough superlatives to describe Half Dome. Yosemite is a monument to the sculptural grace and sheer destructive force of glaciation. During past ice ages, the valley was covered by glaciers with only the tops of the domes and El Capitan poking through. Half Dome’s vertical face is so smooth that it appears to have been sliced off by a butter knife.

Go climb a rock.

Within an hour from the Happy Isles trailhead, you reach a bridge from where you can admire the sights and sounds of Vernal Fall. While climbing the slippery stone steps along the aptly named Mist Trail, water droplets rapidly bead up on your jacket. The rock staircase culminates at the top of the surging Nevada Fall.

Solid and unbroken Liberty Cap

A footbridge traverses a ravine above the Merced River. Then the trail merges into the John Muir Trail with the large granite wall of Liberty Cap to the north. Over the next couple of miles is a refreshingly flat interlude through Little Yosemite Valley, with the Merced River to the south.

Half Dome Hike: famous Cable Route
120′ Cable Route with vertical cables and perpendicular hikers

At Half Dome’s eastern saddle, the Half Dome Trail climbs really steep switchbacks up the shoulder and ends at the base of the notorious cable ladder. Grab a pair of gloves from the pile and climb the vertical and vertigo-inducing cable route to the top. This is a legendary outdoor experience and your life is literally in your hands, so squeeze tightly and watch out for people above and below!

Not only will you enjoy breathtaking views of Yosemite Valley, you may even get to see some patches of snow.


At Yosemite National Park, begin from Happy Isles (shuttle stop #16), about 0.5 miles from the trailhead parking lot or 0.75 miles from Curry Village.
