Stuart Fork to Emerald, Sapphire, and Mirror Lakes Professional Review and Guide
"The long canyon of Stuart Fork and the three lakes at the head are breathtakingly beautiful in spite of a long history of human use and abuse. The hike to the lakes is delightful, although not exactly a wilderness experience. Don’t expect solitude—Stuart Fork is one of the most heavily used trails in the Trinity Alps. However, overcrowding is only a problem if you insist on camping at Emerald or Sapphire lakes. Farther down the valley, Portuguese Camp, Morris Meadow, Oak Flat, and other campsites can accommodate large numbers of campers without feeling crowded."
