The Rio Paraguai-Mirim is a clear-water stream located in the Pantanal region near Corumbá, Mato Grosso do Sul. It flows for approximately 5 kilometers through this ecologically rich wetland. The river is renowned for its crystal-clear waters, which are suitable for swimming and floating. Primary access is by boat, with a common starting point being a journey of about three hours down the Rio Paraguai from local communities, or from the city of Corumbá, which is roughly 140 kilometers away. The overall experience is focused on nature observation and ecotourism within the Pantanal. Notable sights include the surrounding Pantanal landscape and the Serra do Amolar. A specific local attraction is a visit to a traditional pantaneira school. The river is a known fishing destination, with species like Barred sorubim, Piavuçu, and Spotted sorubim being common. The area is a conservation refuge, and there is community-based tourism development, with operators like Aguapé Ecoturismo Pantaneiro offering guided float tours. The remote, boat-access nature of the area suggests limited on-site facilities, with tours likely providing necessary amenities.
