Mount Besar

Mount Besar is a stratovolcano with a distinctive cone shape rising to about 1,900 meters, built up from many layers of volcanic material accumulated over time. The mountain sits on the western side of Sumatra and displays the typical steep slopes characteristic of this type of volcano.

The volcano experienced its last recorded eruption in 1940, an event that contributed to scientific understanding of volcanic activity in the region. This eruption remains documented as a significant moment in the geological history of Indonesian volcanoes.

Local communities have adapted their farming practices to take advantage of the mineral-rich soils created by volcanic activity. The thermal springs and geothermal features around the mountain remain important to daily life and local traditions.

Access to the volcano requires arranging transportation through nearby towns and traveling with local guides familiar with the area. It is essential to check current safety conditions and obtain proper information before planning a visit to ensure compliance with local regulations.

The mountain hosts the Marga Bayur solfatara field, an area with visible steam vents and hot springs scattered across its northern, southern, and western slopes. This geothermal zone aligns with the Semangko fault system, revealing the complex geology beneath the surface.
