The short version: Boulder, tucked against the iconic Flatirons, is Colorado’s outdoorsy college town — world-class hiking and climbing right from the edge of town, the lively pedestrian Pearl Street Mall, a stellar food-and-beer scene, and the CU campus. It’s about 30–45 minutes from Denver. Part of our Colorado trip-planning guide.
