Lake Toba is the largest volcanic lake in the world, 100 km long and 30 km wide, measuring 505 m at its deepest point. Surrounded by tall mountains, it cradles the large island of Samosir in its middle. Lake Toba lies in the northern part of Barisan Mountain Range, which is volcanic and traverses Sumatra Island from northwest to southeast as its backbone. Based on the topographic feature and the wide distribution of volcanic ejecta around the lake, is a giant caldera or cauldron. The mountains around the lake are called Batak Highlands.
The local Batak people are very respectful and loving Christians. Some of the local males may try turn on the charm too much especially if you are a group females. You will see a wonderful local Batak performance that is a mixture of traditional dances and fantastic drinking songs (Lesoy!!- Cheers!!). Everyone is so talented it seems as the local people watching the performance also join in or start up their own sing along table after the main show.
