The Capital of Colorado is Denver, the largest city in the state and a key hub for transportation, culture, and business in the Rocky Mountain region. Known as the Mile High City due to its elevation, it serves as a base for excursions into the mountains and nearby towns.

Why is Denver the Capital?
During the territorial period, the governmental center shifted between several settlements, and Denver became the permanent capital. The Colorado State Capitol building is located in the city and houses the state legislature. Visitor information is available on the Colorado General Assembly website.
What to See in Downtown Denver?
You can explore the Capitol area, museums, parks, and commercial streets. Tours of the Capitol building depend on availability and operating hours, so it is recommended to check in advance and not to visit without confirmation.
Altitude Affects Your Visit
Denver is situated at a relatively high altitude. On the first day, drink water, reduce exertion, and limit alcohol. Those continuing immediately to higher mountainous areas should allow their bodies time to acclimate and seek medical advice if necessary.
When is the Best Time to Visit?
Summer is suitable for city and mountain tours, although afternoon storms are possible. Winter is cold and snowy, and spring is unpredictable. Weather can change rapidly, so it is advisable to check the local forecast close to your activity day.
The Short Answer
For a general knowledge question or crossword, the answer is Denver. Do not confuse the capital of Colorado with Washington D.C., the capital of the United States.
