More About Calero County Park

In 2009, POST purchased the 966-acre Rancho San Vicente from private developers, who had originally intended to build a luxury housing development. The ranch property is an important piece in completing a 15-mile greenbelt from Los Gatos to near Highway 101 in Morgan Hill. POST has since transferred the property to the Santa Clara County Parks and Recreation Department who incorporated it into Calero County Park in 2018.
