The mission of the Hill Country Alliance is to bring together a diverse coalition of partners to preserve the open spaces, starry night skies, clean and abundant waters, and unique character of the Texas Hill Country.

Land

Thirteen Texas rivers begin in the Hill Country and provide water for millions of downstream neighbors.
