Sharptail Ridge Open Space and Trail

Sharptail Ridge Open Space closes for hunting in the fall, as regulated by Colorado Park and Wildlife.  

Sharptail Ridge trails challenge visitors as they extend from undulating prairie foothills into the hidden, rocky hogback and then climb for miles through Douglas County’s Nelson Ranch and Pike Hill Open Space properties via Swallowtail and Ringtail trails, and joins the Pike National Forest Indian Creek trails in the beautifully wooded front range foothills.  Make this a half-day or full-day hike or horseback ride.

Sharptail Ridge is a regionally significant movement-corridor for wildlife – including elk, deer, wild cats and ground-nesting birds. This open space was acquired in partnership with Colorado Parks and Wildlife and Great Outdoors Colorado with the commitment by Douglas County  to be responsible custodians of the wildlife on this land. As part of this charge, dogs and bicycles are prohibited at all times to ensure wildlife traveling the corridor are not disturbed.
