Coronado, CA, April 2021. Coronado was named for the Coronado Islands off the coast of San Diego. They were first sighted November 8, 1602 by Spanish navigator Vizcaino. He named them “Los Coronados” or “the crowned ones,” for four martyred saints of ancient Rome whose death had been on that day. Until 1969, Coronado could only be reached by ferry or by driving along a narrow, seven-mile isthmus called the Silver Strand, which attaches Coronado to the mainland. Ferry service became more limited with the opening of the sweeping $50 million San Diego-Coronado Bridge. This graceful, five-lane, two-mile bridge is the only officially dedicated scenic highway of its kind, due to its unique beauty.
