Snow-fed rivers tumble over granite boulders in the Rocky Mountains, creating an ideal environment for fly-fishing and whitewater rafting. The state's most famous river -- the Colorado -- flows from headwaters in Rocky Mountain National Park, with alternating stretches of heart-pounding hydraulics and quiet areas where you can wade out and cast your fly. Stay at a Bureau of Land Management campground along the shore, or at private riverside cabins such as those found at Colorado Cabin Adventures 3 miles from Grand Lake. For a more remote experience, stay at Cottonwood Cove, tucked along the banks of the Rio Grande just downstream from the picturesque mining town of Creede.
