In the middle of Lake Toba, there is an island called Samosir Island. Samosir Island has two small lakes, Lake Aek Natonang and Lake Sidihoni. Samosir Island which has an area almost equal to the vast country of Singapore is not an empty island, the island is home to Batak Samosir tribe. Batak tribe who live d Samosir Island still hold firm belief ancestors. They also still run various rituals that ancestors used to do first. 
In Samosir Island there are two villages visited by many tourists, namely Tomok and Tuktuk. Tomok is a village that has many interesting attractions such as the Tomb of King Sidabutar, the Batak Museum and the popular Sigale-gale puppet dance performance. In contrast to Tomok which has many historical sights, Tuktuk is a village where there are many inns for tourists. 
Not only the island of Samosir which became the attraction of this tourist spot, Lake Toba is also surrounded by pine forests and several waterfalls and also a hot bath in the forest. The scenery around the lake is very beautiful with a relatively cool air so you will feel at home lingering here.italic
