The Rio da Prata in Mato Grosso do Sul, Brazil, is renowned for its exceptionally clear and clean water, with one source noting it is considered the third cleanest river in the world. This high water quality creates a visually striking aesthetic, with transparent waters ideal for viewing the riverbed and aquatic life. The river's character is defined by a popular guided floating or snorkeling activity, which involves a route of approximately 1,700 meters from the meeting point of the Olho D'Água and Prata rivers, followed by another 500 meters of flotation on the Rio da Prata itself, ending at a stone deck. This full tour experience, including travel and walking, typically lasts about four hours, suggesting a leisurely, observation-focused paddling or floating experience rather than a strenuous journey. The area is part of a rich natural environment, with opportunities for hiking through rainforest and birdwatching, with 234 species of birds noted. The river is located in the Jardim region. The prevalence of organized tour descriptions implies that guided commercial flotation is a primary activity on this stretch of the river.
