Medan is known for its diversity, and this is reflected in the range of attractions that you can experience here including a strong Tamil influence, a large Chinese community, and the indigenous Batak people who also call Medan home. Medan is famously home to Lake Toba, the largest volcanic lake in the world. Lake Toba is an extraordinary natural wonder of the world. This enormous crater lake consists of an island almost the size of Singapore in its center. At over 1,145 square km, and a depth of 450 meters, Lake Toba is actually more like an ocean. This is the largest lake in Southeast Asia and one of the deepest lakes in the world.
