Moored in San Pedro, the Battleship USS Iowa Museum lets you wander through one of the most magnificent and surprisingly personal pieces of U.S. naval history. Known as the “Battleship of Presidents,” the Iowa once carried FDR across the Atlantic and later served through WWII, Korea, and the Cold War. As you move through the ship’s narrow corridors and out onto the decks, you get a real sense of what life was like for the crew: giant gun turrets towering overhead, cramped bunks stacked in rows, and glimpses of the command centers that once buzzed with activity. Veteran volunteers are often on hand to share stories or point out easy-to-miss details.

Named after Erechtheus, king of Athens and foster son of Athena, the Erechtheion is an ancient Greek temple on the north side of the Acropolis dedicated to both Athena and Poseidon. This intricate temple was designed to accommodate the radically uneven ground on the site and to avoid disturbing sacred shrines like the altars to Poseidon, the sacred olive tree, a well containing sea water, the tomb of Kekrops, and the Pandrosion sanctuary.

About a 25-minute drive north from the cruise ship port in George Town you'll find Hell. Roughly the size of half a football field, this peculiar area is famous for its short, black, ironshore karst formations. The jagged structures make Hell appear rather treacherous. Part of the attraction is the Hell Post Office. Send a postcard to your friends and family!
