Island on an island on an island There are several places where islands on islands in turn have lakes with islands – triple islands. The largest known example is a 2 acre / 0.8 ha island in the largest lake on Glover Island, Newfoundland. An island in a crater lake on Volcano Island, Lake Taal, Luzon, in the Philippines, is often said to be the largest island in a lake on an island in a lake on an island, but the one in Newfoundland is about twice as large.
