Castle Rock's Fourth of July 2026: Festival Park, Fireworks Time, and Where to Park

Castle Rock is doing the Fourth the way it should be done: a full evening at Festival Park, live bands, food trucks, a pie contest, and a fireworks show worth staying up for. If you want the classic small-town Independence Day, this is the one in Douglas County to build your night around.

The celebration runs 5:30 to 9:30 p.m. on July 4 at Festival Park in downtown Castle Rock. The Denver Dolls open at 5:30, the Castle Rock Band takes over at 6:45, and Thunder Roads closes it out at 8. In between there is the annual Pie Bake-Off, food trucks, and the kind of family programming that makes it easy to show up early and settle in.

Then the main event. At roughly 9:30 p.m., a three-shot salute kicks off the Town's professional fireworks display, a 20-minute show launched from Miller's Landing, off Plum Creek Parkway just east of Philip S. Miller Park. It is a real show, not a token handful of shells.

Parking downtown on the Fourth fills fast, so give yourself a cushion. The Perry Street garage is your best structured option, and we would plan to arrive 30 to 60 minutes early for a good spot in the park and a reasonable walk back to the car. If you would rather skip the crush entirely, the show launches high off Miller's Landing, so the open areas and trails around Philip S. Miller Park give you a clear view without fighting for a Festival Park blanket spot.

Two things to know. Early risers can start the day with the sixth annual Rock-It Run, a 5K that goes off at 7 a.m. at the fairgrounds. And keep an eye on the sky: if conditions do not cooperate, the fireworks slide to Sunday, July 5. Given the dry summer and the Stage 1 fire restrictions across the county, a quick check of the Town's page before you head out is worth the ten seconds.

Of all the Fourth of July options in Douglas County this year, Castle Rock's still feels like the whole package.
