They may not be the tallest or the most-hiked of the state's fourteeners, but Aspen's Maroon Bells are some of Colorado's most photographed peaks, especially during the fall. Groves of aspen around the craggy sandstone mountains turn yellow as they prepare to shed their leaves, staining the nearby slopes and valleys bright gold — and drawing in gaggles of leaf-peeping tourists who pay $10 to drive down the park's access road. The quintessential place to snap a picture is from the shores of Maroon Lake, but it can get crowded; strap on a backpack and ramble down a trail into the surrounding White River National Forest for a chance to find your own aspen grove — and maybe catch a glimpse of a moose or beaver — before the trees drop their colors and the snow settles in.
