Juniper Valley loop, Sandstone Ranch Open Space Since opening in the fall of 2020, Sandstone Ranch Open Space has become a go-to for outdoor lovers living between Colorado Springs and Denver. Douglas County proclaims the 2,000-plus acres the “crown jewel” of its open space portfolio, which seeks to preserve the area’s rural heritage. That heritage is found at Sandstone Ranch — homestead remains dating back to the 1870 can be viewed from sloping meadows sprinkled with red rock formations. The master plan calls for more opportunities for discovery. For now, there’s plenty of splendor along the 12-mile trail circuit shaped like a figure eight.
