Take an incredibly scenic hike to Young Lakes in the backcountry of Tuolumne Meadows, Yosemite. Some of the best campsites in Yosemite can be found here.
The Young Lakes trail starts from the Lembert Dome parking area and then winds up around 6 miles into the high country past alpine meadows and stunning views of the surrounding mountains. Lower and Middle Young Lakes are beautiful, but you're going to want to push on to Upper Young Lake, where you'll find the best views of the lot. One of my favorite campsites can be found here, but you'll have to explore around to find it :) In the summer, a jump in an alpine lake is just what you need after a long day of hiking.
Enjoy the fantastic sunset, stars, and sunrise over Ragged Peak, Mount Conness, and the rest of Tuolumne!
