The island covers 3.17 square kilometers and remains completely uninhabited by mammals. Because it serves as a critical wildlife sanctuary, visitors cannot roam freely. You must stay with a certified guide while exploring the interior paths.

Known as the 'Island of Birds', this area supports large populations of frigatebirds, pelicans, and cormorants. Bring binoculars to get a closer look at the nesting grounds without disturbing the animals.
