Isatabu Jungle

Isatabu, or Guadalcanal, rises into a mountainous interior cloaked in tropical rainforest. Mount Popomanaseu is its highest summit, and the Mbokokimbo is its longest river. Archaeological finds at Poha Cave and Vatuluma Posovi show an ancient history of settlement; in 1568 Pedro de Ortega Valencia of Mendaña's Spanish expedition named the island after his Andalusian home town.
