Lake Toba
Lake Toba is the world's largest volcanic lake, a breathtaking natural wonder in North Sumatra. Formed by a massive supervolcanic eruption over 74,000 years ago, its serene waters now fill a colossal caldera, with the island of Samosir rising from its center. Surrounded by lush, green mountains and traditional Batak villages, Lake Toba offers a peaceful retreat. Travelers can explore the unique culture by visiting ancient royal tombs and stone chairs, or simply relax and enjoy the cool, clear lake with activities like swimming, kayaking, and hiking.
