Castle Rock brings back First Fridays summer series in Festival Park

Castle Rock is bringing back First Fridays as a June-through-August draw for Festival Park, pairing free concerts with a free 5K, food trucks, cocktails and kids’ activities in the middle of downtown. The 2026 lineup begins June 5 with Mallrats, continues July 3 with That Arena Rock Show and closes Aug. 7 with Six Million Dollar Band.

The town set festivities to start at 5:30 p.m., with live music running from 6 to 9 p.m. The free 5K fun run and run-walk is part of each evening, and the town describes the course as unofficially timed and requiring a waiver. Families can register for the run, then settle in with chairs or blankets for a night of entertainment at Festival Park.

That format makes First Fridays more than a concert series. It is part of Castle Rock’s effort to keep downtown busy during peak summer evenings, when restaurants, retailers and other businesses around Festival Park benefit from the extra foot traffic. The town has long framed its downtown as the community’s center of gravity, and events like this help keep that identity active as Castle Rock grows.

Festival Park, at 300 Second St., sits in the heart of Downtown Castle Rock and serves as home base for First Fridays, the Farmers Market and the Western Heritage Welcome. The park includes a pavilion, two fire pits, a splash pad, open lawn, creekside picnic area and Wi-Fi, and it sits where the East Plum Creek Trail meets the Sellars Gulch Trail, making it a natural gathering place for residents and visitors moving through the downtown core.

The town’s 2026 series follows a format that already proved familiar in 2025, when First Fridays also ran June through August. A July 4 edition expanded the concept with family activities and fireworks viewing, showing how the town has used the same downtown venue to scale up for bigger crowds while keeping the events centered on public space.

For Castle Rock, the point is not just entertainment. First Fridays keeps people in downtown on Friday nights, ties recreation to the business district and gives local merchants a built-in summer crowd at one of the town’s most visible public spaces.
