Rancho Aptos was a 6,686-acre (27.06 km2) Mexican land grant in present day Santa Cruz County, California given in 1833 by Governor José Figueroa to Rafael Castro.
Rafael Castro built a wharf, five hundred feet long, to ship hides, flour, and lumber during the 1850s.
[4] With the cession of California to the United States following the Mexican-American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored.
[7] In 1867, Castro leased the wharf to Titus Hale,[8] who extended it five hundred more feet into the sea.
By 1872, Claus Spreckels, the sugar millionaire, began buying the land from Castro.
