Most of Medan’s top attractions are focused around food and you can sign up for a food tour, or simply go it lone and explore the sights, smells, and tastes of the city by yourself. Home to the largest ethnic Tamil community in Indonesia, Kampung Madras is known as Medan’s Little India. Indians’ history here dates back to the mid-19th century, when the Dutch colonialists sent Indian workers to the area, mainly as construction workers. Lake Toba, also known as Danau Toba, is one of the most popular tourist attraction in Sumatra. Tourism in Lake Toba is fairly developed, but it still holds its own quiet charm. It is the largest volcanic lake in the world measuring at 1,707 sq ft. It is formed by a gigantic volcanic eruption some 70,000 years ago and is probably the world’s biggest caldera. This largest volcanic lake is located in Sumatra, Indonesia. Samosir island (Pulau Samosir) within the lake is the island inside of the island of Sumatra.
