Gruta do Lago Azul
Gruta do Lago Azul information
The centerpiece of this large, vaulted cave is a luminous underground lake with incredibly clear water and seemingly immeasurable depths (over 70m by the current estimates). The cave lies 20km west of Bonito and is worth visiting for the strange stalactite formations alone. It’s truly miraculous in late December and early January, when the sun shines in at just the right angle, illuminating the lake. Wear sturdy footwear.
