Pitcairn island is a great example of getting far away from it all

Islands and territories tend to defy a tidy geographical hierarchy. On a planet covered 70% by interconnected oceans, in a literal sense every place is an island. But the really big ones we think of as continents, leaving the smaller islands – scattered far and wide – as the "leftovers" of geography, which often makes them some of the most unique and interesting destinations.

These articles group them for the traveler (sometimes bending official geography to do so):

• Islands of the Arctic Ocean - near-polar territories north of 60°
• Islands of the Atlantic Ocean - islands in the east and south Atlantic
  • Caribbean - the West Indies and more, a part of the Americas
• Islands of the Indian Ocean - island territories and nations, big and small
  • East African islands - including Madagascar and several smaller islands
• Islands of Oceania - islands found in the equatorial and southern regions of the Pacific Ocean
• Antarctic Islands and Subantarctic Islands
