Medan,the capital of North Sumatra, is on the northern part of Sumatra. Lake Toba ,The Pride of Medan Indonesia,also known as Danau Toba in Indonesia is the largest volcanic lake ( crater lake ) in the world. World famous is the crater Toba Lake in the Batak highlands; approximately five hours drive from Medan. Toba Lake is the largest lake in South East Asia and also one of the most spectacular, surrounded by tall mountains and with the large island of Samosir in the middle. If we descend from the mountain we see the lake glittering in all its beauty. The Dutch writer Rudy Kousbroek even called Toba Lake, 'the most beautiful place on earth'. Most visitors stay on the peninsula of Tuk Tuk on Samosir, named after the linguist Herman Neubronner van der Tuuk. In general people stay several days on Samosir to discover the island, to visit traditional Batak villages, to swim in the lake and go to the hot springs in Pangururan.
