"Up to Glen Aulin, this trail coincides with the High Sierra Camps Loop (Trail 15), the Pacific Crest Trail, and the Tahoe–Yosemite Trail. Scenically, this popular hike to Glen Aulin is noted for the pools, rapids, cascades, and falls it passes. Because this hike takes you downhill first, it is ideal for hikers unaccustomed to high elevations. Spending a night at Glen Aulin or farther down along the Tuolumne River gets you partly acclimated, preparing you for the hike back up to your trailhead."

"The easy hike to Glen Aulin is a Yosemite classic. Wide meadows, sweeping vistas of rounded granitic domes, and pulsating waterfalls on the Tuolumne River all combine to make this an exceptional area. Even if this trail were not so spectacular, it would still be very well used. In addition to the High Sierra Camp, Glen Aulin lies on the Pacific Crest Trail (PCT) and the Tahoe–Yosemite Trail, and it is also a pivotal point for many hikes on the east side of the park. Because of the popularity of this area, make your backpacking reservations early. If you would like to see more of this beautiful area and less of your fellow visitors, continue on from Glen Aulin to the relative peace of the subalpine McCabe Lakes."

"There are more scenic wonders along the Glen Aulin trail, mile for mile, than on any other route below the high alpine zone anywhere in Yosemite. For most of its length it follows the course of the Tuolumne River as it wanders through broad meadows beneath the fabulous domes and spires of the Cathedral Range, then rushes and tumbles down in waterfall after waterfall as the canyon steepens and narrows. Your goal, the High Sierra Camp lies in an idyllic setting beside a pool at the base of an exquisite cascade. Because the route is fairly short and easy, because it is part of the High Sierra Camp loop and the Pacific Crest Trail, and because it is so beautiful, the trail always has plenty of traffic and wilderness permits go quickly. Solitude? Not a chance, but worth the trip anyway."
