Thousand Islands

The Thousand Islands are a chain of islands that straddle the U.S.-Canada border in the Saint Lawrence River as it emerges from the northeast corner of Lake Ontario. The islands stretch for about 50 miles downstream from Kingston, Ontario.

The Canadian islands are in the province of Ontario. The U.S. islands are in the state of New York. The islands, which number 1,865 in all, range in size from over 100 km² to smaller islands occupied by a single residence, to even smaller uninhabited outcroppings of rocks that are home to migratory waterfowl.
