Nuku Hiva is the biggest of the Marquesas Islands in French Polynesia. The coastline of western Nuku Hiva is characterized by a steep, but fairly regular coastline, cavernous sporadically by small bays leading to deep valleys, which lead into the interior. In 1813, Commodore David Porter claimed Nuku Hiva for the United States, but the United States Congress never ratified that claim, and in 1842, France took ownership of the whole group of islands, establishing a settlement on Nuku Hiva. The population is about 2,400 inhabitants. This was the site for Survivor: Marquesas, the fourth installment of the popular CBS reality television show.
