Mount Sibayak is an active volcano in northern Sumatra, Indonesia in the town of Berastagi that erupted more than 100 years ago. It is 2 212m high, and is relatively easy to climb.
We began our expedition at 4:30am and reached the peak of the volcano after a hour.
On the mountain, there was a strong smell  of sulfur emitted by the steam vents.
From the mountain top, we also got a bird’s eye view of the whole town of Berastagi.
Mount Sinabung, a superactive volcano, can also be seen from the top of Mount Sibayak.
And of course, climbing a volcano is incomplete without seeing its crater. Its crater has a small lake with acidic discoloration due to the seepage of sulfurous gases.
After trekking, it was good to relax dipping ourself in a hot bath from the hot spring.
Overall, it was an unforgettable experience to hike to the top of a volcano and see its crater, sulfur mine and indulge in a healing bath thereafter.
