Cathedral Lakes in the backcountry of Yosemite is one of the most popular day hikes in Tuolumne Meadows. That afternoon we hiked the 4 miles up to the Upper Cathedral Lake. The lake is stunning and one of the most scenic with the monolithic Cathedral Peak in the background. We hiked around the lake and climbed up to the ridge to enjoy this viewpoint as the sun was setting. If you were to choose a day hike in the Tuolumne Meadows Cathedral Lakes would be the one.
