Caprica Beach
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
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 waterfront (Miniseries, opening credits), the portion seen appears to have a seawall rather than a beach.
Caprica Beach was presumably a picturesque or pleasant locale, since Tigh describes the barren moon as its antithesis.
