September starts our annual cool down from the long summer, but also brings FREE fun across the Mile High City, thanks to the Scientific and Cultural Facilities District. As always, there’s so much to explore and experience in Denver on the cheap, thanks to our city’s generous FREE Days at museums and attractions. Remember that some places require you to get a timed ticket in advance, while others allow for walk-ins. Be sure to check policies before you head out.

Review our events calendar for easy planning.
Many frugal folks are well-versed on FREE Days at museums and attractions across the city. Therefore, rather than posting each date individually, we created a comprehensive list of all the FREE days for easy one-stop planning. There’s even a button you can click on to print out the latest list.
Most of the FREE days are funded, in part, by taxes collected through the Scientific and Cultural Facilities District. Others are funded by corporate sponsorship.
We are fortunate to live in a city with so many wonderful institutions to enjoy on the cheap.
