Guide to Rocky Mountain National Park
"For the more adventurous and experienced hiker, Patterson recommends hiking to Chasm Lake on the east side of the park. The lake sits at the base of Longs Peak, the park’s highest point and one of Colorado’s 14,000-foot peaks. The out-and-back trail to Chasm Lake is 8.4 miles and requires a steady climb through a subalpine forest and into the alpine tundra." - Travel + Leisure Editors
