The coastal landmark named Caprica Beach has never been seen, but is mentioned by Saul Tigh in the episode "Bastille Day". Tigh sees photos of frozen water deposits on a moon and promptly says, "Not exactly Caprica Beach down there, is it?"
The beach's specific location on Caprica is unknown. While Caprica City is shown to have a beachfront (Miniseries, opening credits), viewers cannot readily be certain that this area is the beach that Tigh mentions.
Caprica Beach must have been a very picturesque and pleasant locale, since Tigh considers the barren moon as the antithesis of the beach.
