Or fly there with Google earth.  The authors of "The Elusive Beaches of Eleuthera" have a great website (where you can also buy their book about beaches on Eleuthera and other stuff) and have a really cool Google Earth page which flies you above that island, or if you zoom out, the other Bahama islands. Go there and they give you instructions on downloading Google Earth (it is free) if you don't already have it.

Family Island maps

Maps of each of the Family Islands can be found on the visitors guides.
