    North Sumatra combines the vast crater lake Toba, Batak culture, active volcanoes, and Gunung Leuser National Park's orangutan-filled rainforest. Most trips begin in the metropolis Medan.
    North Sumatra has around 15 million inhabitants; its capital is Medan. The classic route takes you from Medan to Bukit Lawang for the orangutans, then into the Karo Highlands to Berastagi with the volcanoes Sibayak and Sinabung, and finally to Lake Toba with Samosir Island. This circuit typically requires about a week. The roads are winding and often slow; most travelers use shared taxis, minibuses, or a car with a driver. Further south are West Sumatra with Bukittinggi and the Mentawai Islands.
