City insight: Castro Valley
Castro Valley is a census-designated place in Alameda County, California, and the fourth most populous unincorporated area in the state, with 66,441 residents at the 2020 census. It is named after Guillermo Castro, a 19th-century Mexican Californio rancher who owned the land. At about 37.7 degrees north, the climate is Mediterranean with dry, warm summers and mild, wet winters, so spring and autumn are the best seasons to race.
