Gruta do Lago Azul, Bonito

4.6
Gruta do Lago Azul enjoys a reputation for its deep blue lake and numerous fossils of large prehistoric mammals, including giant sloths and saber-toothed tigers. Local indigenous people discovered the entrance to the cave in 1924, and were probably the first to set foot inside. The underground lake is over 60 m (200 ft) deep, but the subterranean river that feeds it remains undiscovered to this day. See how the blue water twinkles when touched by the sunlight streaming from a hole in the ceiling.
