Alpine meadows, tundra and lakes, two summits, and Colorado's largest glacier? All of this and more can be yours for the low, low price of a ten-ish-mile out-and-back accessed from Nederland's Rainbow Lakes or Fourth of July trailhead. Pack up your personal locator beacon and as much water as you can carry to bag these summits, either from the west side of the Continental Divide via Columbine Lake or the Devil's Thumb trailhead near Fraser. The west-side traverse is closer to 25 miles, so while this hike can be done on one of Colorado's arctic-length summer days, the pro move is to reserve a campsite (or two!) through the United States Forest Service and arrange for drop-off at a trailhead west of the divide and pick-up at a trailhead east of the divide.
