Following the Trail to Young Lakes
Two trails lead from Tuolumne Meadows up to Young Lakes - the Glen Aulin Trail and the Dog Lake Trail. The Glen Aulin Trail, which we describe here, is slightly shorter and easier. The Dog Lake Trail involves about 500 feet more climbing before descending to join the Glen Aulin Trail 1.6 miles from the lower lakes. If you can't get a permit for one of the trails, try the other.

Dog Lake Trail Junction to Lower Young Lake,
1.6 miles
Several hundred more feet of climbing along a trail that gradually lessens in severity leads to a ridge only a quarter mile from the lake. A gentle descent soon reveals Lower Young Lake. The trail hugs the northern shore. Many backpackers swing up into the scattered trees here to find campsites.
Since campfires are not allowed, campsites are wherever you find an appealing spot back from the water's edge. Middle Young Lake is another half mile of hiking. Upper Young Lake requires the ascent of a steep, primitive trail.
