A fantastic, hard, hike in Yosemite National Park, beginning at the Sunrise Parking Trailhead at Tenaya Lake and culminating in Clouds Rest peak with amazing view of Half Dome, the Yosemite Valley, and the wilderness all around us. Very popular trail and destination. This was an out & back hike totaling 12.8 miles and 2,645 Ft of total ascent. The second mile was a steep climb of over 1,000 Ft in a one mile climb. Many parts of the trail have built-in stone stairs. The last part of the climb is on somewhat narrow rocky area, but it is wide enough to where 1 or 2 people can walk this section with no fear.
