The Zapata Ranch is owned by The Nature Conservancy and managed through a one-of-a-kind partnership with Ranchlands. The property is a 103,000-acre bison and guest ranch located on the eastern wall of the San Luis Valley of Southern Colorado. It borders the Great Sand Dunes National Park and Preserve, the newest National Park in the United States. The high desert grasslands, alpine forests, wetlands, sand dunes, creeks, and lush meadows offer one of the most scenic and ecologically diverse landscapes in the United States. In addition to our livestock operation, the ranch features working ranch vacations, educational programs centered around our bison herd, and active, ambitious conservation programs aimed at preserving the surrounding land and promoting its biodiversity.
