The Mentawai Islands are a chain of islands off the west coast of Sumatra in Indonesia, known to the surfers of the world as a "perfect-wave" paradise.
Accessible only by yacht charter, the Mentawai Islands are home to the Mentawai Islands rain forests ecoregion, home to many endemic species, including Four endemic primates.
The island of Nias to the north has one of the few Megapthic cultures in existence today.
