Twelve Hills Nature CenterAs an additional bonus property this year - after the tour - please stop by the Twelve Hills Nature Preserve.  Twelve Hills is an urban nature preserve right here in the heart of Oak Cliff.   It serves as an outdoor classroom and passive recreational area. It seeks to educate both adults and children about environmental stewardship and community-building through the grassroots creation and maintenance of a native Texas blackland prairie, and small wetland.
 
Twelve Hills is a very beautiful addition to our local urban environment that seeks to keep a part of our blackland prarie topography pure and untouched.
