Samosir Island

An island within Lake Toba and itself one of the world's largest lake islands, Samosir is the cultural heartland of the Batak Toba people. Traditional Batak houses with curved, boat-shaped roofs and elaborately painted facades are found in villages such as Ambarita and Simanindo, alongside stone-age megalithic monuments and royal ceremonial grounds. The island's hills rise to around 1,000 meters above the lake surface, offering panoramic views back across the caldera water.
