Be in the know before you light up.

Before we dive in, though, keep in mind that any firework that leaves the ground is illegal in the state of Colorado. So if you are going to celebrate Independence Day with friends and family, make sure you are doing so in a safe and legal way. Now, we've already given you the lowdown on where you can watch professional fireworks in Colorado, but if you're wanting to have little fireworks celebrations of your own, well, you've come to the right place!

Many (and we mean MANY) areas across the state have placed bans on all fireworks and even canceled their annual firework shows due to the recent wildfires and the pandemic. Below is a complete list of where fireworks are legal in Colorado.

If your area has not been listed, well, we're afraid you're out of luck ... However, if you'd like more information on your specific area, please contact your city or county officials directly.
