Middle and Upper Gaylor Lakes and Old Mining Ruins Trail

Overview
This 4.6-mile round-trip hike takes you on a journey through stunning alpine terrain in Yosemite National Park. Starting from the Gaylor Lakes Trailhead located off of Tioga Pass Road, the route offers breathtaking views of the High Sierra, serene lakes, and a glimpse into history at the old mining ruins. 

Description
The hike begins with a steep but manageable climb from the Gaylor Lakes Trailhead, quickly rewarding you with sweeping views of Tuolumne Meadows and surrounding peaks. After about half a mile, you'll crest a ridge and descend into a peaceful alpine basin where Middle Gaylor Lake sits, reflecting the surrounding granite ridges.

Continuing along the trail, you'll pass by Upper Gaylor Lake, nestled in a rocky bowl with pristine waters perfect for a quiet rest. From there, the trail climbs again to the remnants of the Great Sierra Mine, where you'll find old stone cabins and mining equipment from the late 1800s. This area offers both a fascinating historical perspective and stunning panoramic views of the Yosemite high country.

After exploring the ruins, return the way you came.

Flora and Fauna
The trail is surrounded by hardy alpine flora, including lupine, Indian paintbrush, and sedges. Keep an eye out for marmots, pikas, and alpine birds like Clark’s nutcrackers. In late summer, wildflowers add splashes of color to the landscape.
