What is the altitude of Denver and will it affect me?

Denver sits at 5,280 feet above sea level (1 mile). If you’re coming from a lower elevation you may notice yourself getting our of breath quicker. To avoid altitude sickness, be sure to stay hydrated (consider carrying a water bottle with you wherever you go), give yourself a day or two to adjust before you take on any strenuous hikes or activities, and limit alcohol consumption. Be sure to pack or pick up some sunscreen as well, the clear Denver sky’s and higher elevation can expose you to more sun than you might expect.
