The Koroyanitu National Park hosts 100 bird species. Coral coast hills average 300 m, dissected by Rewa River (160 km). Formed by Pacific plate subduction, Vanua Levu island's Natewa Peninsula rises to 1,033 m. Remote Lau Group's volcanic cones reach 500 m. This archipelagic topography includes 17 protected areas with crested iguanas and 500 plant species on 330 islands.
