Interested in volunteering?

Jeffco Open Space has been the natural choice for volunteering since 1972. Ever since a grassroots campaign resulted in the creation of our agency, volunteers have been pitching in for their parks – from helping to preserve natural resources and educating visitors to blazing new trails.
