Hidden Mesa Open Space and Trail


Open Space Enjoyment and Social Distancing

As you anticipate an enjoyable day on Douglas County Open Space properties, please be aware that some trails, due to the location and terrain, have limited space for remaining socially distant from those other than in your immediate party. Please be aware when you encounter these circumstances, adjust accordingly, and help keep our community safe by adhering to
COVID-19 social distancing requirements.


Hidden Mesa is a vast property. An adventurous trail system connects the meadow and the mesa.  The trail names say it all “Rocky Pass” is literally a trail within a vein of ever-changing cobblestone.  Whereas, “Pleasant Pass” is a challenging yet pleasant alternative.  The Upper Rim Loop takes people through a meadow and along a rocky outcrop. The property adjoins Gateway Mesa, for a total of 276 acres of open space that is managed and owned by the Town of Castle Rock. Gateway Mesa is open to hikers with a parking lot and 3.5 miles of trails on the south side of Hwy. 86.

Hidden Mesa is also home to the County’s research and demonstration orchard.
