Lake Huron is one of the Great Lakes, on the border between the
United States and Canada. In the Canadian part of the lake, there’s
an island called Manitoulin, the largest island in the world that lies within a lake.
And on this island is a lake, called Lake Manitou, that might be called a lake-within-a-lake! It covers about 41 square miles, making it the largest lake of its kind on earth. And in Lake Manitou you’ll find a few islands, islands-within-an-island!
