Berastagi is a town in North Sumatra, Indonesia. Basically, the city is located in the highland, so it’s quite a cold place.
It is recommended that you know someone with a car in Medan, the closest biggest city in North Sumatra with an airport, because public transport to Brastagi is quite bad, often people squeeze inside a bus and some even sits on top of the roof of the bus.
Some of the places you can visit around the town includes Sibayak, Sinabung mountains, Sipiso-piso Falls, Traditional Karonese House at Lingga Village, Lake Toba (Tongging).
