The Creston District is in the south east side of Paso Robles AVA, centered somewhat around the town of Creston. The topography is comprised of old erosional plateau at the base of the La Panza Range along with alluvial terraces and fans of Huerhuero Creek. Elevations run from 1,000 – 2,000 feet.

Soils are typified by old, well developed terrace and hillside soils along with a mix of granitic and sedimentary rocks.

Creston (named after Calvin J. Cressy) was founded in 1884 on the Rancho Huerhuero Mexican land grant.

Cardiff Stud Farm (Creston Farms) is a place owned by Canadian-American television personality Alex Trebek, and where a number of retired American thoroughbred racehorses are taken care of, including:
