Yosemite National Park: Half Dome at Full Moon

Let the soft light of a full moon guide your way to Yosemite’s most iconic granite peak on this 14.2-mile out-and-back.

Trip Tools

This 14.2-mile trek to Half Dome—under the guiding light of a full moon—gains more than 4,000 feet of elevation. Make sure to turn off your headlamp and marvel at the starry skies.
From Happy Isles campground, turn right on the paved path and cross Vernal Falls Bridge. Pass Illilouette Falls Vista, where Yosemite, Illilouette, Vernal, and Nevada Falls can be seen simultaneously. Merge onto the 3-mile Mist Trail and watch your footing on the trail’s sometimes-slick granite (raingear will come in handy by the waterfalls on this trip).

Keep left at the Y-junction after Vernal Falls and continue along the Merced River. Once you reach the Y-junction at Yosemite Valley, turn left up the John Muir Trail. After about 2 miles, bear left onto Half Dome Trail. From here, grab giant cables to climb the last stretch up Half Dome to (if you’ve timed it right) a once-in-a-lifetime sunrise view.
