This Open Space was opened June 2006. This ride is lollipop shaped. It features a 2.1 miles loop at the top of the mesa designed for mountain bikers. Somewhat technical but fun for all. Ride the loop in either direction.
From Castle Rock take Highway 86 east toward Franktown. Turn left at Parker road and continue on for approximately 1 mile. Hidden Mesa Open Space will be on your left.
