Sontang

Sontang lies in the northern Minangkabau borderlands, among streams that drain the hills towards the Rokan basin. The Sontang watercourse is part of this network of tributaries, which carries water away from the highlands of Pasaman into the plains to the east. Forested slopes and river valleys shape a landscape between the mountain country of western Sumatra and the great lowland rivers that reach the Strait of Malacca.
