Kamojang, Stratovolcano in Garut, Indonesia

Kamojang is a stratovolcano located in Garut that rises to approximately 1,730 meters and displays active geothermal features across its slopes. Numerous steam vents, fumaroles, and hot springs emerge from the volcanic terrain, showing clear signs of ongoing thermal activity beneath the surface.

Geothermal exploration at the site began in 1926 when Dutch colonial authorities drilled five wells to investigate the thermal potential of the area. One of those original wells, designated KMJ-3, continues to produce steam today and demonstrates the long-term viability of the geothermal resource.

The name Kamojang is used both for the crater and the geothermal field that supplies steam to the power station. The first modern geothermal plant in Indonesia was commissioned here by President Soeharto in January 1983, and the field is now operated by PT Pertamina Geothermal Energy. Visitors can see the steam vents and hot springs that remain part of the landscape.

The crater lies in Ibun district, Bandung Regency, about 45 km southeast of Bandung via Majalaya and Ibun, or roughly 25 km northwest of Garut through Samarang. The geothermal field sits on the slopes of Mount Guntur, about 7 km west of the peak. Expect hot ground and steam vents near the trails.

The steam at Kamojang is classed as VD (Very Dry), with so little water content that it can drive turbines directly, without the water-separation step needed at most geothermal fields. This dryness is why the field was described as among the best in the world. Well KMJ-3, drilled to 66 metres in 1926, still releases steam.
