Poço da Lontra is a small, enchanting natural pool on the Rio Salobra, located on a private farm near Bodoquena in Mato Grosso do Sul.

The pool is modest in size — roughly seven meters in circumference and two meters deep — but its water is strikingly clear, transparent, and tinged green. Surrounding rocks are draped in dense vegetation, and tiny fish dart through the depths.

A wooden staircase provides access to the water's edge.

The pool is one of several natural highlights along the popular "Boca da Onça" ecotour, which guides visitors through a series of waterfalls and swimming holes in this corner of the Serra da Bodoquena region.

Poço da Lontra is consistently noted as one of the most beautiful stops on the route.
