Denver, with its little brother Boulder, is the mecca of the young, hyperactive, multisport American urbanite. This unique guide to their world proves the point: the options for mountain biking, climbing, hiking, mountaineering, fly fishing, whitewater kayaking, ice climbing, paragliding, backcountry skiing, snowshoeing, and more seem blissfully endless--and all within (or a half day's drive from) the city limits. Each chapter covers a favorite adventure sport or activity, including top metro destinations along with brief profiles of the best gear outlets and extreme envelope-pushers to introduce readers to Denver's exciting, colorful adventure culture. For easy planning, all destinations are presented in four parts from city center and the suburbs to the foothills and outlying attractions in the Front Range and beyond.
