The Gunung Sibayak is a small volcano overlooking the town of Berastagi in northern Sumatra, Indonesia. Although its last eruption was more than a century ago, geothermal activity in the form of steam vents and hot springs remains high on and around the volcano. The vents produce cristalline sulphur, which was mined on a small scale in the past. Seepage of sulphurous gasses has also caused acidic discolouration of the small crater lake.
The Gunung Sibayak ("gunung" means mountain, while "sibayak" is a term from the Karo Batak language referring to a founding community) is relatively easy to climb and became a tourist attraction already in colonial times.
