Main image

Mount Binaiya is the highest mountain on Seram Island in Indonesia’s Maluku province, with a summit around 3,027 metres. The peak forms the core of a large, biodiverse montane area.

The mountain and its surrounding forests have long been home to local communities and are part of protected conservation areas established to preserve endemic species and habitats. Scientific and conservation interest has grown because of the high level of local endemism.

Mount Binaiya sits near the centre of Seram Island in Maluku province, with its upper slopes protected within national park boundaries; the nearest larger population centres are coastal settlements on Seram, with overland access routes into the central massif.

  • Province high point: Highest point in the Maluku province at about 3,027 metres, dominating the central massif of Seram Island.
  • Access and terrain: Reaches through dense tropical forest to alpine terrain; summit treks typically require multiple days and local guides due to remote, rugged conditions.
