Summary

The Cook Islands are a Pacific island country with both high volcanic islands and low lagoon landscapes. Communities, coastlines and distinct island forms create varied experiences within a shared regional cultural setting.

The contrasts are central to their appeal. Mountainous ground and coral lagoons show different stages of island formation, while continuing island cultures give the seascapes a human identity.

The essential experience.

A detail that changes the visit

Outer-island connections and lagoon conditions need flexibility; the archipelago is not one compact resort area.

For the curious reader

History, landscape and context.

The Cook Islands is an island country in Polynesia, part of Oceania, in the South Pacific Ocean. The country consists of 15 islands whose total land area is approximately 236.7 square kilometres (91 sq mi). The Cook Islands Exclusive Economic Zone (EEZ) covers 1,960,027 square kilometres (756,771 sq mi) of ocean. The Cook Islands is self-governing while in free association with New Zealand. Since the start of the 21st century, the country has conducted its own independent foreign and defence policy, and also its own customs regulations. Like most members of the Pacific Islands Forum, the country has no armed forces, but the Cook Islands Police Service owns a Guardian Class Patrol Boat, CIPPB Te Kukupa II, provided by Australia, for policing its waters.

From inspiration to a practical plan

Plan your visit.

Physical demands
Beach walking can be gentle; lagoon outings add boat boarding and swimming, while inland Rarotonga hikes are steep.
The consequential detail
Outer-island connections and lagoon conditions need flexibility; the archipelago is not one compact resort area.
