Sandstone Ranch 2019 Guided Access

August 6 –  Due to confirmed cases of  the Vesicular Stomatitis Virus in Douglas County, Guided Horseback Rides in August have been cancelled. With safety as our primary concern horses, cattle, or other livestock will not be allowed onto Sandstone and Prairie Canyon Ranch until further notice.   Thank you for your cooperation and patience during this time.  If you have any questions or concerns, please direct them to Mary Ann at or 303.660.7495.


It’s time to experience Sandstone Ranch!  Join Douglas County Open Space staff and volunteers for a guided hike, horseback ride or activity.

The County is in the process of developing the Sandstone Ranch Master Plan. The Master Plan seeks to balance the preservation and protection of the Ranch, with public access. While the Master Plan process is underway, Douglas County also recognizes the importance of public access.
