Ocean, Island, Lake, Island, lake, Island?

Here's a strange one :). An island with a lake, the lake has an island, the island has a lake, and the lake has an island :). Let me break this down :). The Pacific Ocean is home to t he Philippines, which is home to the island of Luzon. The Island of Luzon has a lake named Taal. Taal Lake has an island of it's own, Taal Volcanic island. Taal Volcanic island has a lake as well, Crater Lake. And finally Crater Lake has an island, Vulcan Point Island.

Lake Taal (below) is located on the island of Luzon.  In the middle of this lake is the is Taal Volcanic Island.

And a view of Crater Lake's island,  Vulcan Point Island.

So.. if you are sitting on Vulcan Island,  you are sitting on an island, on a lake, on and island, on a lake, on an island in the ocean!  3 islands for the price of 1 :).
