Nearly 1.2 million visitors visited Colorado's cities in 2009, including the state's largest city and capitol, Denver, the Denver Convention and Visitors Bureau (CVB) reports. Tourism is Denver's second largest industry, generating $3.1 billion in annual spending while supporting 65,000 jobs. The 16th Street Mall, Cherry Creek Shopping District and LoDo were Denver's top attractions in 2009, with the Denver Zoo, Red Rocks Amphitheatre and the Colorado Rockies baseball team topping the list of the city's paid attractions that year, CVB officials note.

"Tourism plays a vital role in Colorado's economy. It's one of the largest industries in the state, employing more than 144,000 people, so we are encouraged by the increase in visitation last year, especially given the significant decrease experienced in other parts of the nation," said Don Marostica, director of the state's office of economic development and international trade.
