About this site
Arorangi Passage sits off the west coast of Rarotonga, the main island of the Cook Islands, near the village of Arorangi. This side of the island faces the open Pacific through a break in the fringing reef, with sites in this area typically reached by boat from operators along the west and south coasts.
