Samosir Island, or Pulau Samosir, is a large island in the middle of Lake Toba. It is situated north of Sumatra, Indonesia. The island is surprisingly just a little smaller than the country of Singapore and is located nearly exactly in the center of the lake. The lake is considered to be the fifth largest in the world. It is said that the island and water surrounding it was formed due to a volcanic eruption 75,000 years ago. Sadly, this massive eruption also caused the extinction of some species residing on the island. The town of Pangururan of Samosir Island is connected to Tele of main land Sumatra. Lavish forests, rocks, swamps and a small lake are few of the numerous great things to see in the island.
