Geography of the Cook Islands
21°14′S 159°46′W / 21.233°S 159.767°W
The Cook Islands is located in Oceania, in the South Pacific Ocean, about halfway between Hawaii and New Zealand. The country can be divided into two groups: the Southern Cook Islands and the Northern Cook Islands. Rarotonga in the southern group is the main island. All the other islands are known collectively as the Pa Enua or Outer Islands.
The land areas of the southern islands range in size up to the 67-square-kilometre (26 sq mi) Rarotonga, while none of the northern islands are bigger than 10 square kilometres (3.9 sq mi). The most populous islands are Rarotonga with a population of 11,000 and Aitutaki with 1,800; none of the other islands have more than 500, and a few are uninhabited.
Two terrestrial ecoregions lie within the Cook Islands territory: the Central Polynesian tropical moist forests and the Cook Islands tropical moist forests.
