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.

  • Excelent trip. It's just very fast. It takes around 1 hour.
  • Lovely experience that you should add to your Bonito itinerary. Note there is a special time of year early in the morning that you can see the cave in its glory, but it was still a site to behold. Note: the cave is very hot and humid!
