The Thousand Islands are more than 1,800 islands located in 35 miles of the upper St. Lawrence River between Upstate New York and southeastern Ontario. During the latter half of the 19th century, the region evolved as a vacation destination, initially for Canadian and American urbanites drawn by the restorative powers of spectacular scenery and relaxed summer life. Tourism expanded rapidly, and by the early 1900s, the Thousand Islands boasted dozens of grand hotels, daily railroad connections to New York and Philadelphia, steamship service to Montreal and Toronto, innumerable sightseeing and guided fishing excursions, and the best that North America's premier vacation spot could offer.
