Fairgrounds Regional Park, Trail and Dog Park

Head to Fairgrounds Regional Park for a fun-filled day in the Colorado sunshine. Watch a youth football, baseball or soccer game.  Bring your furry friend to play and rid itself of excess energy in the dog off-leash area.  Enjoy the view of Castle Rock’s namesake and then take the trail to walk downtown for some food or ice cream.

Size:  37 acres


500 Fairgrounds Rd.
Castle Rock, CO 80104


Open one hour before sunrise and one hour after sunset
