Lagoa Misteriosa, which means “Mysterious Lagoon”, is a lake at the bottom of a sinkhole, a type of geological formation common in limestone regions. This lake of transparent waters impresses visitors for its incredible depth. It is considered one of the deepest submerged caves in Brazil, with more than 220 meters of water column (maximum depth reached by professional cave diver Gilberto Menezes de Oliveira, in 1998), which explains why is called mysterious. The tour begins with a short interpretive trail through the forest of 600m approximately. The access to this lake of blue waters is made by a staircase of 186 steps, comfortable and safe. The snorkeling is indescribable: be amazed by contemplating the vastness of the Mysterious Lagoon. Divers reported that visibility reaches 40 meters. The floating experience is circular. The reception area features a bar and restrooms.

*The Lagoon visitation remains subject to weather conditions, usually open only from May to September due visibility conditions (it requires cold weather).
