Denver is pretty much one mile above sea level and is therefore also called “Mile High City”. The city’s international airport is the second largest in the world in terms of surface. Finally, Denver is the largest city within a radius of 800 kilometers, as a glance at the map of the American Southwest immediately confirms.
Those who only know the airport of the city definitely missed something. Despite its size, the city can be easily explored by walking. There is a free shuttle bus on 16th Street Mall, downtown’s main street. This is also where the 10 colorful pianos are located, inviting passers-by to give a little concert on the street. Don’t miss the blue bear at the Colorado Convention Center which is 13 meters high, and the horse on the giant chair in front of the public library.
