Known as "The Mile High City" because of its elevation, Denver is both the capital and the largest city in the state of Colorado. The city is just northeast of the center of the state, located on the plains just east of the Rocky Mountains. The Rockies loom on the western horizon of the city, in fact downtown Denver is about 15 miles from the foothills.
Even though most people associate Denver with snow and cold, the weather can be unpredictable at times because of its proximity to the mountains. It has a semi-arid climate, with drier winters than you would expect. Much of the snow that hits the moutains doesn't reach the city.
When visiting Denver there are some great museums and parks to visit, as well as a variety of restaurants. There are plenty of fun things to do, and the Molly Brown House Museum (just a few blocks from the capitol building downtown) is a must-see. There are also many fascinating mining towns to visit year round in the hills throughout the state, each with unique attractions.
There is a light rail system that serves parts of the city, depending where you want to go.
Also there is a major Airport that serves Denver, Denver International Airport, however it is in the plains 23 miles east of the city. It is pretty far from anywhere of interest, but there is the public skyRide bus system that leaves at least once an hour, and takes about an hour, that can get you from the airport to downtown for $8 one way. A taxi from the airport to downtown could run you upwards of $50, and shuttle vans are another option.
