What’s interesting in Lake Toba is about its people. They are ethnically Bataks. You can see those traditional Batak houses from a distance, by its distinctive roofs which curves upwards at each end, exactly like how a boat’s hull is. The colors of Batak houses are also easily recognisable. Toba people are prideful and assert their identity as ‘Batak’. Much to do with their Batak cultures, their rich and complex burial traditions and pre-colonial religious ideas. There are also some interesting sights such as the monumental sculptures carved from large trees, the Batak Totem pole.
