Welcome to Berastagi
Since it's only two hours out of Medan, it's still a popular weekend retreat, when main-street traffic almost comes to a standstill. For travellers the main attraction is climbing active volcano Mt Sibayak and exploring the surrounding Karo Highlands and villages, where vestiges of indigenous Karo Batak culture remain in the shape of the immense wooden houses with their soaring thatched roofs and cattle-horn adornments.
On a clear day you can see both Gunung Sinabung to the west and the smoking Gunung Sibayak to the north. Sinabung erupted without much warning in the summer of 2015, causing the evacuation of thousands of people resident on its foothills. It still erupts intermittently and is off-limits to hikers indefinitely.
