The Thousand Islands are a group of more than 1,800 islands in the St. Lawrence River, straddling the border of the U.S. and Canada. A fashionable retreat for the elite in the late 19th century, today the area is a hub for outdoor activities. It’s home to elaborate island mansions such as the German-style Boldt Castle on Heart Island, and Singer Castle on Dark Island, with its Gothic windows and secret passageways.
Thousand Island National Park
Thousand Islands National Park, formerly known as the St. Lawrence Islands National Park, is located on the 1000 Islands Parkway in the Thousand Islands Region of the Saint Lawrence River. The islands are actually the worn-down tops of ancient mountains.
