The Aguas Milagrosas Sinkhole, and scuba diving site

King VulturesScuba diving in 180 meters deep cave!

A sinkhole is a nature-made hole on the earth surface caused by removal of soil or bedrock, usually both, by water. Also called sink, shake hole, swallow hole, swallet, doline or cenote, sinkholes are found worldwide and may be formed gradually or suddenly. They are common where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by ground water circulating through them.

Diving enthusiasts enjoy exploring this water-filled sinkhole and is the site of Brazil's deepest cave dive. We do not know if is a bottomless pit, once there are no studies about it.

The Serra das Araras, a narrow peninsula of Amazonian forest follows the southern edge of the mountain range which give its name, is an ecotone between the cerrado (savanna-like) vegetation and the southern Brazilian amazonia. This makes its avifauna be a real treat. The phantom endemic Blue-eyed Ground-Dove was seen once in 1986 at the Serra das Araras Ecological Station, not far from here.

The reason why we were visiting this site was because we were doing scuba diving in a 180 meters (540 feet) deep cave!!! One of the few Brazilian caves which are allow to dive in.

Diving is another universe, and there are no words to express the feeling, the solitude, the encounter with yourself. Just magical.

Yeah, but we were birding too and found King Vultures in the same doline we were diving, Red-legged Seriema, Campo Flicker and Buff-necked Ibis in the fields around the restaurant, Point-tailed Palmcreeper and Sunbittern nearby, while Golden-chevroned Parakeets were crossing the sky above us. The hills around us host a mix of Amazonian and Pantanal birdlife with Gray-headed Tanager, Flavescent Warbler, Black-fronted Nunbird and others.
