Anatakitaki Cave
A limestone cave on Atiu holding the kopeka, a swiftlet that navigates by echolocation.
Updated 16 October 2026
Anatakitaki is a cave in Atiu's makatea, the raised coral platform that rings the island, and it is home to the kopeka, the Atiu swiftlet, a bird found nowhere else that nests in the dark and finds its way by a clicking echolocation that can be heard as you go in. The walk to the cave crosses sharp coral through bush, and the chambers inside hold stalactites and a pool.
Background
Anatakitaki, also called the Cave of the Kopekas, lies in the northeast of Atiu. This karst cave, 1 km long, was formed by solution and branches into many side chambers and passages, with formations of every kind along its length. A freshwater lake lies at its base, joined to the Pacific by the Tiroto Tunnel, which can be waded until its last stretch goes fully underwater. The swiftlets roost here in vast numbers and never land outside the cave. Roots, mostly from banyan trees, reach down to its deepest parts.
