Medan is the capital city of North Sumatra province, Indonesia. When you visit Medan, do not miss its largest lake in Southeast Asia, Lake Toba. Lake Toba has its own island in the middle of the lake called Samosir Island. The island delivers a laidback vibe so you can explore the area by bike easily. Scenic views of waterfalls, highlands, and combined with Batak culture will be one experience you get to share to your friends at home.
