Once seen as the domain of cowboys and oilmen, today the mile-high metropolis is a cosmopolitan mix of natural beauty and world-class hotels, entertainment and attractions. The Denver Art Museum houses one of the finest collections of American Indian art in the world. The city is also the official home of four national teams: the Broncos, Nuggets, Rockies and Avalanche, meaning every season is sports season. Even with all the big-town glitz, Denver has managed to maintain its earthiness. Outdoor recreation is still a major draw. With 205 parks in the city and 20,000 acres of parks in the nearby mountains, there's ample opportunity for hiking, mountain biking, mountain climbing and more -- families visiting Denver won't know where to begin. The Zoo, the Children's Museum and the Botanic Gardens offer hours of entertainment. Or visit the United States Mint for a free tour. To prove that Denver really is "The Mile High City", head to the State Capitol. There's a spot on the west steps of the building that is exactly 5,280 feet above sea level.  More info
