About Pulau Sangeang

Pulau Sangeang is an island in West Nusa Tenggara, Indonesia, dominated by the active volcanic cone Sangeang Api. The volcano is the island’s defining feature and has produced ash plumes and eruptions that have impacted surrounding airspace and nearby islands.

The main reason people travel in the area is to observe or study the volcano and its effects from a safe distance; the island itself is hazardous during eruptive episodes and may be closed to visitors. Local coastal waters are part of the Lesser Sunda island chain and are approached by fishing and transport vessels when conditions allow.

The island sits north of Sumbawa in the Lesser Sunda Islands and is administered within West Nusa Tenggara province. Access is by boat from nearby islands or mainland ports when the volcano is quiet.

  • Safety: The island contains the active volcanic cone Sangeang Api; access is unsafe during eruptive activity and is managed by Indonesian authorities.
