Mount Balbi

Mount Balbi is a dormant stratovolcano on Bougainville Island in Papua New Guinea standing 2,715 meters (8,907 feet) tall with five volcanic craters on its eastern side. The largest crater contains a substantial lake formed within the volcanic cone, shaping the landscape below the summit.

The volcano formed approximately 10,000 to 12,000 years ago during the Holocene epoch with no recorded eruptions since human settlement of the region. Its slow geological development has shaped Bougainville s landscape over multiple millennia.

The communities of Bougainville view this peak as part of their ancestral lands and integrate it into their daily beliefs and stories. Local knowledge about the mountain's pathways and features has been passed down through generations of residents.

Accessing the mountain requires permits from local authorities and hiring experienced guides familiar with the terrain and conditions. Proper equipment for steep slopes and unpredictable weather is essential for anyone attempting the ascent.

The summit area contains an active solfatara field where numerous fumaroles release volcanic gases through the ground surface. These steaming vents reveal that geothermal activity persists beneath the mountain even in its dormant state.
