The Medano-Zapata Ranch sits in the San Luis Valley of southern Colorado, bordering the Great Sand Dunes National Park and Preserve, the newest national park in the United States (2020). It is a quilt of  scenic and ecologically diverse meadows, wetlands, sand dunes and cottonwood groves, promoting ranching’s role in preserving and protecting natural landscapes. 
Their motto is “working together to live with the land.” Believing that ranching, with its connection to the land and its dependence on the long-term vitality of the resource base, represents a critical alternative for landscape-scale conservation in the American West.
They run a herd of bison on a single 50,000 acre pasture and a herd of Angus mother cows as well as accepting visitors and offering all manner of activities.
