Sumatra

Sumatra is known for its dramatic landscapes. A long chain of mountains and volcanoes runs almost the entire length of the island, creating some of Indonesia's most stunning scenery. Right in the middle of it all is Lake Toba, the world's largest volcanic lake.

In the middle of the lake sits Samosir Island, home to the Batak Toba people. The landscape here feels surprisingly different from what you'd expect in Southeast Asia. Rolling grasslands, pine trees, and buffalo grazing across the hills make it look more like an African plateau than a tropical island. And what's even more amazing is that this entire lake was formed by a massive supervolcano eruption thousands of years ago.

The local culture is just as fascinating. Traditional Batak houses, known as rumah bolon, are easy to recognize with their curved, saddle-shaped roofs. They're not just beautiful—they also reflect Batak beliefs, family heritage, and clan identity.

But what really makes Lake Toba special is the contrast. Within just a few hours, you can go from open savannas to lush rainforests, all while exploring villages built on the remains of one of the biggest volcanic eruptions in Earth's history.
