Geological Exploration & Nature Walk
Discovering Batu Cermin Cave
Batu Cermin (Mirror Stone Cave) is a historic geo-heritage site providing fascinating geological evidence that Flores was once submerged deep underwater. Embedded across the high limestone walls are ancient fossils of marine corals, prehistoric fish, and sea turtles dating back millions of years. It earned its name because morning sunlight piercing through narrow ceiling crevices reflects off mineral-salt rock walls, producing a brilliant mirror-like shimmer.
