Santa Fe County approved a Master Plan for the 2,440-acre Thornton Ranch Open Space property located northwest of Galisteo, NM along Camino de los Abuelos (CR 42). As the owner of 1,904 acres of this land, it is Santa Fe County’s largest land holding. Most recently part of a 17,000 acre cattle ranch owned by the Thornton family, it is centrally located within the Galisteo Basin, one of the most significant cultural landscapes in the Southwest.

The Thornton Ranch Open Space Master Plan offers a vision and guiding framework to safeguard this public open space property while providing opportunities for recreational trails use. The plan outlines the development of a trail network that offers a unique recreational and educational experience for hikers, bikers, and equestrians.
