Aranuka is an atoll of Kiribati, located just north of the equator, in the Gilbert Islands. It has an area of 11.6 square kilometers and a population of 1,057 as of 2010[update]. By local tradition, Aranuka is the central island of the Gilbert group.
Aranuka is an atoll with a triangular shape, predominantly formed by two large islands, made up of two islands with the mainland Aranuka harboring the two villages of Buariki and Baurua. Takaeang is the other inhabited islet that lies 7.68 kilometers west of mainland Aranuka. Both islets are unusually large for an atoll of this size. These islands are connected by long sandbanks on the northern side and an underwater reef crest on the southern side which also has a wide pass to the lagoon in the centre.
There is only one road that runs alongside the lagoon-side of the island where villages are located and a network of access and feeder roads running from the main road to other parts of the island. These pathways generally are wide enough to accommodate pushbikes and motorbikes but not big trucks. All villages are located on the lagoon side on both sides of the main road, easily accessed by walking, with bicycles, motorbikes and trucks.
Aranuka has a lagoon, but this is not so rich in shellfish. There is a passage into the lagoon, available for the boats in moderate weather, through the middle of the reef on the southwestern side of the atoll. There are several dangerous points in the passage where tidal streams can be very strong. Aranuka is known for its old stand of Rhyzophora stylosa mangroves that have grown as tall as coconut trees and are now a breeding site for birds. These mangroves can be found towards the northern end of mainland Aranuka.
The island of Aranuka had only two villages since its first establishment. In 1978, Baurua village was established with only a few inhabitants, less than 10 houses, making a total of 3 recognized villages now for Aranuka. The current populations of the villages are:

Aranuka is by tradition the island in the middle of Kiribati and the location for the formation and separation of all the islands of Kiribati which was first started by the God of our Ancestors, Nareau. That is why Aranuka was formerly named and known as Ananuka – the middle of it.
At some point between 1860 and the late 1880s, the islands of Aranuka and Kuria were conquered by Tenkoruti (King Karotu), the paramount chief of Abemama, when a former ruler (Ten Temea) of Kuria and Aranuka gave up these two islands to King Karotu from Abemama and left for Maiana, another of the Gilbert group. They were then ruled by Tenkoruti's nephew, Tem Binoka. 
 Visiting Aranuka
Aranuka is an island of unique natural beauty, with white unspoiled sandy beaches and sparkling blue waters as well as being the only island in Kiribati to have tall mangrove trees with heights of more than 15 meters. The uninhabited islets of the island also provide the world class swimming and snorkeling spots for visitors.
