Esmeralda Basin–Gallagher Head Lake Loop

15 mile loop with 3,000 feet of elevation gain, 5,960 ft high point

This route loops around the Esmeralda Peaks, up through some of Washington’s best wildflower meadows and rock gardens, past tumbling creeks, to ridge crests offering dramatic views of near and distant peaks, including Mount Rainier, Mount Daniel, Glacier Peak, and others the Cascade Crest. A short, optional side trip along the County Line Trail leads to a high overlook above tiny Lake Ann. The main loop then continues across serpentine barrens over Fortune Creek Pass, down to Gallagher Head Lake, and then through De Roux Basin back to the trailhead. For the most part, the route climbs and descends steadily, but there are a few short, steep sections and some creek crossings (none hazardous).
