Samosir is the world’s largest island within an island, created by an ancient volcanic eruption in the midst of Lake Toba. At nearly 2,000 sq. km, the majestic cerulean blue lake of Danau Toba is also Southeast Asia’s largest. Linked to the Sumatran mainland by a narrow isthmus, discover the spectacular natural beauty of the lake island in the shadow of ragged hills. Samosir Island also holds much social and cultural interest, being an important center for the Toba Batak people of Indonesia. The locals are predominantly a peaceful Christian population, many of whom continue to live in colorful traditional homesteads or ‘rumah adat’. Since getting to this island paradise can be challenging, with the nearest airport about five hours away in Medan, Samosir is worth at least a few days visit.
