Lagoa Misteriosa lies at the bottom of a 75 m deep sinkhole, fully covered by trees and surrounded by forest. Entirely underwater, the cave is considered the seventh deepest in the country. It begins as two almost vertical shafts, about 6 m in diameter, which meet at around 60 m.
The first dive in the lagoon was made in September 1992 by Augusto Auler, during the Expedição Franco-Brasileira Bonito 92. In November of the same year, Jorge Hallak reached 82 m in Poço B and suffered a serious decompression accident. In June 1998, Gilberto Menezes reached a collapse cone 220 m below the lake level, in an 8-hour dive using 8 breathing mixtures. Closed to visitors since 2005 for lack of a Speleological Management Plan, the lagoon reopened in 2011, after licensing.
Underwater you see two blue shafts, rock walls, fallen trunks, deposits of white sand, branches with golden leaves and small fish.
