Samosir is an island located in the center of Toba Lake, North Sumatera; an island with 1000 meter above sea level height. Samosir is actually a new regency in Sumatera Utara, which was inaugurated as a regency in January 2004. Before that, Samosir is a part of Toba Samosir regency. This new regency consists of 9 districts, like Pangururan (the capital), Harian, Sianjur Mulamula, Nainggolan, Onan Runggu, Palipi, Ronggur Nihuta, Simanindo, and Sitio-Tio.
Each district has its own tourism objects, which are organized by the government and the local citizen. However, the potential of those areas are not maximized yet. Not many promotions are done to attract tourists to come here.
The lack of good access to the island is one of the factor which obstruct the development of Samosir as a tourism object. To reach this island, a long trip must be done. From Medan to Prapat needs 4 hour driving, and then 45 minute for crossing the lake from Ajibata dock. However, if you use a speed boat, it will only take 10 minutes to arrive at Samosir Island.
Samosir Island is believed as the origin of Batak people which is centered in Pusuk Buhit, Sianjur District. Pusuk Buhit is a hill range with 1800 meter above lake level height. This hill is believed by the Batak as the universe or the place for God to appear.
In the foot of Pusuk Buhit Hill there is a village name Sianjurmulamula which has a cultural site in the form of King Batak house miniature. According to local people, King Batak was originated from Thailand which crossed the pacific sea until he finally arrived at Sianjurmulamula. However, there is also another source said that King Batak was originated from India.
