The Adirondacks, in New York's north country, is a land of crystal clear lakes and splendid mountains. Adirondack Park takes up around two thirds of Upper New York State. The Adirondacks is best known for Lake Placid - home of the 1980 Winter Olympics. Also located within the Adirondacks is Saratoga Springs. The mineral springs here have been revered for centuries for their supposed healing powers. As well, the spas brought the elite of American society to the area, who in turn brought with them the pasttime of throughbred racing—an entertainment that is still strong today. Boldt Castle is located on Heart Island in the Adirondack area and is accessed by a water taxi that ferries visitors to the home for tours. Singer Castle is another example of an opulent home in the area, and is found on Dark Island, also only accessible by boat.
