Things around Denver feel a little (okay, a lot) different this year, but that doesn’t mean that there isn’t still plenty of Halloween fun to be had! After all, it’s Fall in Colorado and Pumpkin Spice everything is everywhere! Check out our list of safe and kid-friendly Halloween Events to make the most of this season!

October 1st – 31st | 9am – 5pm (gates close at 4pm)
