Jazz in the Park runs every Wednesday evening in June, July, and August — 6:30 to 8 p.m. at Festival Park, 302 Second Street in downtown Castle Rock. It pairs with Free Summer Trolley Rides on those same Wednesday evenings (6–8 p.m.), so you can ride the trolley and catch jazz for free.

Yes — the City of Castle Pines Summer Concert Series runs three shows at Elk Ridge Park, 7005 Mira Vista Ln. June 28 (6–8 p.m.): That Eighties Band — Colorado's premier 80s tribute act. July 26 (6–8 p.m.): Narrow Gauge. August 16 (5–7 p.m.): The Long Run — Eagles tribute. All three are free. Pack a blanket or bring a folding chair; no outside alcohol is allowed.

Rock the Mountain Summer Concert Series runs every Saturday and Sunday, 3–6 p.m. at the Outlets at Castle Rock, May 23 through early September 2026. The June 13 show is a special timeslot: 12–3 p.m. (Jordan Yewey). All shows are free — no ticket or RSVP required. Paid parking applies at the Outlets.

Castle Rock's outdoor events at Festival Park (Jazz in the Park, First Fridays) and Philip S. Miller Park (Tunes for Trails) are generally dog-friendly. Dogs must be on a leash. Rules can change event by event — confirm with the Town of Castle Rock at crgov.com or the Downtown Castle Rock Merchants Association before bringing a dog.

Philip S. Miller Park has multiple parking lots and most are free. For Tunes for Trails and Perks for Parks concerts at the amphitheater, the park's main lot off Wilcox Street is the closest option. Check crgov.com for any event-specific parking notices closer to the date.

First Fridays at Festival Park (Jun 5, Jul 3, Aug 7) is a party-style street event anchored by a free 5K at 5:30 p.m. and a concert from 6–9 p.m. in the heart of downtown Castle Rock at 302 Second Street. Tunes for Trails / Perks for Parks is a separate series at the Philip S. Miller Park Amphitheater (Jun 18, Jul 16, Aug 20, Sep 17) — different venue, different vibe (more family/blanket-on-the-grass), and donations to the concert support the Castle Rock Parks and Trails Foundation. Both are free to attend.

You can bring outside food to the Castle Pines Summer Concert Series at Elk Ridge Park — blankets, chairs, and snacks are encouraged. No outside alcohol is allowed. The venue is a public park; check castlepinesco.gov or the Castle Pines Chamber for any updates before each show.
