Arapahoe County Open Spaces hosts a variety of events throughout the year and many are free to the public. Most events take place at the Arapahoe County Fairgrounds and Park but occasionally, we host events at some of our other park locations. Please visit the calendar for a current listing of events.
Step back in time and celebrate a piece of Colorado’s history during our free Fall Festival, hosted by Arapahoe County Open Spaces and held outside at the 155-year old 17 Mile House. There’s fun for the whole family!
