A couple of hours south of Medan, the air changes first. Berastagi sits at altitude between two volcanoes, and after days in the humid lowland jungle, that cooler mountain air alone is worth the drive.
Two volcanoes to choose from
Mount Sibayak is the easier climb: a half-day round trip through pine forest to a crater still venting sulphur steam, doable without technical experience. Mount Sinabung, still active and periodically closed, is best admired from a distance, its plume visible from town on clear days.
The market
Berastagi's fruit and vegetable market is one of the largest in North Sumatra, terraced hillsides of Karo farmland feeding stalls piled high with passion fruit, marquisa, and produce you won't find at lower altitudes. It's as much a place to watch daily life as to shop.
Karo culture
This is Karo Batak country, distinct from the Toba Batak culture further south, with its own traditional houses, customs, and villages within easy reach of town. It's a natural stop between Bukit Lawang and Lake Toba.
We usually include Berastagi as a stopover: a night to cool down, climb, or just wander the market, on the way to somewhere else.
