Mt. Sibayak (Indonesian:Gunung Sibayak) is a small stratovolcano overlooking the town of Berastagi in northern Sumatra, Indonesia. Located in near Town of Berastagi, precisely at coordinate 3°12′0″N 98°31′0″E, District of Karo, Province of North Sumatra, Indonesia.
To reach the top of Mt. Sibayak – 2.212 m or 7,257 ft – it will need about 3 hours from the base camp – actually the place of hotspring or called Village Debu-debu. Debu-debu is about 2-3 hours by bus from Medan, capital of North Sumatra, or 1 hour from Berastagi, capital of Karo District. From Medan to Berastagi is about 3 hour by bus.
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 crystalline sulfur, which was mined on a small scale in the past. Seepage of sulfurous gases has also caused acidic discolouration of the small crater lake.
Sibayak is a term from the Karo Batak language referring to a founding community. It is relatively easy to climb and has been a tourist attraction since colonial times.
