Guides leAD 45-minute tours, up and down many stairs, through this lovely turn-of-the-20th-century castle on Dark Island. The castle, originally known as the Towers, was built as a summer home for Frederick G. Bourne, president of the Singer sewing-machine company. Famed American architect Ernest Flagg modeled the four-story, 28-room structure on a Scottish castle, giving it all sorts of interesting nooks and crannies. To get here, take a boat from Alexandria Bay. Empire
