Colorado
Home to diverse natural ecosystems, Colorado boasts numerous ski resorts, vineyards, canyons, fossil-rich national parks, rugged natural trails, and picturesque scenic drives. Arguably the greatest of Colorado's many natural wonders is Mt. Elbert, the highest peak in the North American Rockies. The state's natural beauty inspired the opening lyrics of the song "America the Beautiful." Aside from its abundant unspoiled wilderness, Colorado also offers many urban attractions, including award-winning restaurants and nationally praised microbreweries. With an extensive system of highways and railroads, the state provides visitors on vacation with a chance to explore this largely untamed part of the country by car or train. Customize your holiday with our United States online travel planner to create an adventure that suits you.
