Aitutaki is one of the Cook Islands, which are in the South Pacific. It consists of a main island, a turquoise lagoon and a surrounding barrier reef. The lagoon’s waters teem with marine life, including rays, bonefish and turtles. Near the main town of Arutanga, trails lead to the top of Maunga Pu hill. Boats run to small uninhabited islands called motu, including tiny Tapuaetai, known for its white sand beaches.
