The world's largest volcanic lake, and the centre of Batak culture. The main travel destination is Samosir Island, especially the small village of Tuk Tuk - almost an island within the lake. Because of its elevation (900 metres above sea level) Lake Toba has an almost ideal year climate, with day time temperatures around 26-28 degrees and night time temperatures around 20 degrees.

Lake Toba (Indonesian: Danau Toba) is a lake and supervolcano, 100 kilometres long and 30 kilometres wide, and 505 metres (1,666 ft) at its deepest point. Located in the middle of the northern part of the Indonesian island of Sumatra with a surface elevation of about 900 metres (2,953 ft), the lake stretches from 2°53′N 98°31′E / 2.88°N 98.52°E / 2.88; 98.52 to 2°21′N 99°06′E / 2.35°N 99.1°E / 2.35; 99.1. It is the largest volcanic lake in the world.[1] In addition, it is the site of a supervolcanic eruption that occurred 69,000-77,000 years ago, a massive climate-changing event. The eruption is believed to have had a VEI intensity of 8. The eruption is believed to be the largest explosive eruption anywhere on Earth in the last 25 million years. According to the Toba catastrophe theory  to which some anthropologists and archeologists subscribe, it had global consequences, killing most humans then alive and creating a population bottleneck in Central Eastern Africa and India that affected the genetic inheritance of all humans today. ... read more

Wikitravel - Lake Toba

Lake Toba

Lake Toba is an immense volcanic lake covering an area of 1707 sq km (1,000 sq km bigger than Singapore) with an island in the center. Formed by a gigantic volcanic eruption some 70,000 years ago, it is probably the largest resurgent caldera on Earth. Some studies say it might have been associated with causing previous ice age/climate change and the largest human population bottleneck ever. Genetic estimates suggests that there where only a few thousand individuals that survived the catastrophe. The island in the middle - Pulau Samosir - was joined to the caldera wall by a narrow isthmus, which was cut through to enable boats to pass; a road bridge crosses the cutting. Samosir island is the cultural centre of Batak tribe who are mostly Christians in the modern days. ... read more
