Mt. Sibayak (Indonesian:Gunung Sibayak) is a small stratovolcano 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 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.
A nice volcano!
Two months ago I tackled Gunung Sibayak — an active volcano in North Sumatra, Indonesia, with three new friends. The visuals, eerie landscape, and risky downclimb were part of an adventure that I’ll never forget.
As an added bonus, I was kept awake all night before the climb by earthquakes rattling my bungalow. I guess that’s what happens when you sleep between Gunung Sinabung and Gunung Sibayak, two of Sumatra’s busiest volcanoes!
I just wrote up a nice four-page feature of the trek for this month’s edition of Leisure Travel Magazine in Southeast Asia.
We were literally climbing in the clouds. Low visibility made finding — and not falling off of — the trail a little tricky sometimes.

The trail leading to the volcano. We were practically the only trekkers for most of the way.
Slippery trails that were initially tricky to find.
Mike (England) and Sebastian (Germany) scramble up to the volcano rim.
The views of the Karo Highlands were amazing before we got up into the clouds. The jungle down there was/is major Karo and Batak headhunter territory.
Not what I expected at all: gases were literally just coming out of the ground around us. No cute, defined hole to relieve the pressure like on other volcanoes. We stank like sulfur for more than a week afterward.
What to do after climbing Gunung Sibayak? Well, Berastagi was quite an exciting town. You could always hang around this giant cabbage monument — the only highlight in town.
And finally, if you get hurt on the volcano, this is where you end up: At Dead on Arrival Mama’s clinic. Hmmmm….
