Aranuka is an
atoll with a triangular shape, predominantly formed by two large islands,
Buariki and
Takaeang, which is the other inhabited islet that lies 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
Rhizophora 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.
Villages The island of Aranuka had only three villages since its first establishment. In 1978, Baurua village was established with only a few inhabitants, less than 10 houses, making a total of 4 recognized villages now for Aranuka. The current populations of the villages are: ==History==
