About Lake Toba
The world's largest crater lake lies so vast it contains an island (Samosir) larger than Singapore, created by a supervolcano eruption 74,000 years ago. Waters stretch 100 kilometers across while volcanic highlands frame the caldera in dramatic ridges. The lake's Batak people maintain distinctive culture, architecture, and cuisine unique in Indonesia.
