"Come autumn, Rocky Mountain National Park shines its brightest and most beautiful. The days may be shorter, but they’re filled with the sounds of bugling elk, comfortably cool temperatures, and some of the most awe-inspiring foliage you’ll find out West. In higher elevations, the alpine tundra turns purple and deep red; throughout the park, aspen and cottonwood trees don their golds and oranges ahead of winter." - Travel + Leisure Editors
