One of the longest and most spectacular caves of the four islands is to the south-east of Atiu, Anatakitaki or the Cave of the Kopekas. This is a large solution cave, a series of large chambers and corridors, with an estimated length of 1 km. A fresh-water lake can be found at the bottom of the cave. The cave itself has a collapsed entrance. Out of this entrance several collapses open to the jungle, where vegetation penetrates into the cave. An especially nice view is of the dangling lianes, the "bell-pulls".

The cave is very nicely decorated with white stalactites, stalagmites and flowstones. The rich and colourful speleothems are typical phenomena of tropical cave development. As a consequence of the relatively shallow and strongly fissured rock layer above the cave, roots of various dimensions have broken through. Some of the roots have also penetrated the speleothems.

The Kopeka are tiny birds, very much like swifts, which nest in huge numbers inside the cave. When they come out to hunt insects they are never seen landing. They only rest in the cave. Inside, in the darkness, they make a continuous chattering, clicking noise, which they use to find their way around. (Like bats, but the bat sounds, of course, cannot be heard by the human ear.)

The Latin name of the Kopeka or Aitu swiftlet is Aerodramus sawtelli. It is endemic on the island and of great interest to biologists. It uses sonar like bats. The species belongs to the swift family, adults are 10 cm long and brown. The term ana means cave in the local Maori, so Anatakitaki actually means Takitaki Cave. It seems the two words are written together for this cave, at least that's the most common variant of the name.

The trails are mostly level with some ladders which must be climbed. We recommend comfortable walking shoes for the tour. The cave is located on the top of the makatea (raised coral), the elevated limestone belt around the island. It is reached on an almost 2 km long hike through the untouched tropical rain forest from Kopeka Lodge. So the tour also includes an introduction into the local flora and fauna, the medical properties of some plants, and some wildlife. You should also bring your swimwear, the tour ends at an underground lake where the members can take a refreshing swing with candlelight.
