Located in the heart of downtown.   A great place to spend a few hours.

16th Street Mall is a little more than 1 mile, starting at Broadway & 16th and ending at the Denver Millennium Bridge. 

The Street is closed to regular traffic;  free buses traverse up and down 16th street picking up and dropping off passengers.   The buses run roughly between 6 am and 1 am - and you usually are not waiting more than five minutes for the next bus.  (RTD Free MallRide)

The Street is home to numerous hotels, retail, and restaurant shops;  representing local and nationwide stores.   Coffee shops are well represented on this stretch of road. 
 

At the Broadway & 16th end, there's the Civic Center Park, the Capitol Building, and the US Mint (a bit further down street).    The street ends with the previously mentioned Millennium Bridge - which takes you over to some additional shops, and a couple of great little parks (Centennial, Confluence, and Common Parks)
