Fodor's Expert Review Glacier Gorge Trail

The 2.8-mile hike to Mills Lake can be crowded, but the reward is one of the park's prettiest lakes, set against the breathtaking backdrop of Longs Peak, Pagoda Mountain, and the Keyboard of the Winds. There's a modest elevation gain of 750 feet. On the way, about 1 mile in, you pass Alberta Falls, a popular destination in and of itself. The hike travels along Glacier Creek, under the shade of a subalpine forest. Give yourself at least four hours for hiking and lingering. Easy.
