Tikehau (meaning Peaceful Landing in Tuamotuan[2]) or Porutu-kai is a coral atoll in the Palliser Islands group, part of the Tuamotu Archipelago in French Polynesia. It is included in the commune of Rangiroa.
The first recorded European to arrive to Tikehau was the Russian mariner Otto von Kotzebue. He called this atoll Krusenstern Island,[a] after Russian explorer Adam Johann von Krusenstern. The Wilkes Expedition passed by this atoll on 9 September 1839.
On a visit in 1987, Jacques Cousteau’s research group made a study of Tikehau’s lagoon and discovered that it contains a greater variety of fish species than any other place in French Polynesia.
Today, Tikehau is a tourist destination, popular for its pink sand beaches and its exceptional underwater fauna.
