Anugrah Sibayak Hot Spring is a geothermal bathing facility on the slopes of Gunung Sibayak, an active stratovolcano in the Karo Highlands of North Sumatra, Indonesia, where volcanic activity drives naturally heated mineral waters to the surface in one of the country's most accessible volcanic hot spring zones. The name Anugrah, meaning 'grace' or 'divine gift' in Indonesian, reflects the local appreciation for the volcanic spring as a natural blessing whose warm mineral waters support both well-being and livelihoods through thermal tourism. Gunung Sibayak is popular with day-hikers from the nearby city of Berastagi, and Anugrah hot spring offers trekkers and visitors an ideal opportunity to soak their tired muscles in naturally heated water after the volcanic climb.
Insider tip — Anugrah Sibayak sits at the foot of Mount Sibayak, an active stratovolcano in the Karo Highlands of North Sumatra, and channels its mineral-rich outflow into bathing pools. The sulfur concentration here is mild enough for extended soaks, and the surrounding highland air stays refreshingly cool year-round. Berastagi town, a short ride away, offers Karo cuisine and fresh produce markets for a full day trip. Arrive before 9 AM on weekends to avoid tour group crowds.
