Mangaia
The southernmost and an ancient island of the Cook Islands, with a distinctive landscape of coral limestone cliffs and caves around its edge.
Mangaia is the southernmost island of the Cook Islands' southern group and one of the geologically older islands in the Pacific. The island is ringed by a raised coral limestone belt (known locally as makatea), forming cliffs and numerous caves, some of which can be explored with a guide, while the lowlands inside have taro fields and small lakes. Few tourists come here, the people are unspoiled and friendly, and the focus is on quiet nature and village life. May to October has the most pleasant weather. You can get here on a domestic flight from Rarotonga.
