Map of Pitcairn Islands.

The Pitcairn Islands are a group of four islands in the south Pacific Ocean: the group comprises Pitcairn Island (a volcanic island), Henderson Island (an uplifted coral island), and two coral atolls, Oeno Island and Ducie Island.

The only inhabited island, Pitcairn, has an area of 5 km2 (1.9 sq mi) and a population density of 10/km2 (26/sq mi); it is only accessible by boat through Bounty Bay. The other islands are at a distance of more than 100 km (62 mi).

Situated in the South Pacific Ocean, about one-half of the way from Peru to New Zealand, they are one of the most remote sites of human habitation on Earth.[1][2]

The only inhabited island, Pitcairn, is at 25.04 south, 130.06 west. Pitcairn is about 2,170 kilometres (1,350 mi) southeast of Tahiti, 5,310 kilometres (3,300 mi) from Auckland, New Zealand, and over 6,600 kilometres (4,100 mi) from Panama.[3]

Maps

Worldwide map services show very little detail of the islands, and are even of limited use to show the location of them with respect to each other and to other islands, because they are so small and far apart. However, Mapquest zoom level 1 is a suitable map to see the location between Peru and New Zealand.

For the location with respect to French Polynesia, see the inset of Image:French Polynesia map.jpg.
