Mangaia Island Map


Mangaia is pronounced "mahng-AH-ee-ah," not "man-gaia," as there's no "g" sound in the Polynesian languages. It's 204 km southeast of Rarotonga and just north of the tropic of Capricorn, a position that makes it the southernmost and coolest of the Cook Islands. South of here you don't strike land again until Antarctica. At 52 square km it's also the country's second-largest island, just slightly smaller than Rarotonga. Without soaring peaks or an azure lagoon, Mangaia doesn't fit the tropical island stereotype and it remains an undiscovered tourist destination.

One of the major geological curiosities of the South Pacific, Mangaia is similar to Atiu and Mauke but much more dramatic. A makatea or raised coral reef forms a 60-meter-high ring around the island with sheer cliffs towering as high as 80 meters on the inland side. Lifted from the sea in stages over the past 18 million years, this outer limestone rim has eroded into quite remarkable rock formations with numerous caves hundreds of meters in length, some of them below sea level.

The volcanic earth inside the makatea is the only fertile soil on the island; this rises in rolling hills to slopes once planted with pineapples. At 169 meters elevation, Rangimotia is the island's highest point. Forested ridges radiate from this hill with the valleys between them used for farming.

Near the inner edge of the makatea, where water is caught between the coral cliffs and the hills, low taro swamps are flanked by banana fields and miscellaneous crops. Nothing but bush and pandanus grow on the makatea itself, and pigs are kept there in makeshift pens. However, some areas of makatea are covered by lush green indigenous forest excellent for hiking.

Legend tells how Rongo rose from the deep with his three sons to colonize the island. Captain Cook "discovered" Mangaia in 1777 and Polynesian missionaries followed in 1826. Mangaia was the last Cook Island to accept Christianity, and traditionally, the 750 Mangaians have a reputation for being a cautious lot, but you'll probably find them quite friendly when you get to know them. They live in three scattered coastal villages, Oneroa, Tamarua, and Ivirua. The population is continuing to drop as people depart for New Zealand and Australia, with 33 percent of the inhabitants leaving 1996-2001. The Mangaians speak a language similar to that of Rarotonga, part of the great Austronesian family.
