Atiu at a Glance
About Atiu
Atiu is a raised coral (makatea) island in the southern Cook Islands group, noted for its limestone cliffs, caves and pockets of native forest and birdlife. It is a small, traditionally organised island with several villages and local agricultural activity.
The island’s geology is dominated by uplifted fossil coral forming steep coastal cliffs and an interior plateau pitted with caves and karst features that are accessible on guided walks. Atiu’s low population and remote location make it a destination for visitors seeking nature-based experiences and cultural visits rather than large tourist infrastructure.
Atiu lies in the southern Cook Islands, within the archipelago east of Rarotonga, and is reached by inter-island flights or infrequent boat services.
