FAQs about flying to Denver

Denver climate

Despite Denver’s reputation as a ski paradise, the city does not have very harsh winters. Denver nestles in the foothills of the Rockies, on the high plains. The Chinook winds warm up the city to average temperatures that are well above other cities on the same latitude. Travellers considering taking cheap flights to Denver might be surprised to learn that Denver gets more sunshine each year than Miami or San Diego. Temperatures do not soar to the 100 degree mark, instead Denver enjoys a warm climate with low levels of humidity year round.

Getting around Denver

You can walk around downtown Denver easily or take public transportation. The 16th Street Mall has a free bus service running down the length of it. It stops every two blocks. To get around Denver, its suburbs and outlying communities, like Boulder and Evergreen, you can take the Regional Transportation District (RTD). It offers bus and light-rail services and has free transfer tickets, but you’ll need exact change. A great way to sightsee is hopping on the open-air Platte Valley Trolley, which has half-hour tours on its “Denver Sightseeing Route” in the warmer months. If you’re heading out of town for the day, you’ll need to rent a car. Be mindful of driving conditions during winter; storms can make driving treacherous.
