The Arroyo Saladillo Dulce is a waterway located in the Departamento San Justo, in the province of Santa Fe, Argentina. The surrounding landscape is characterized by a combination of monte (woodland patches), pajonales (reed beds and grasslands), and numerous aquatic environments, creating a rich mosaic of habitats along its banks.

The arroyo is particularly notable for its wildlife. Bird life is abundant and varied, with black-necked swans, flamingos, gallaretas (coots), and collar ducks (pato de collar) regularly observed along the water. Flamingos are distinguished by their long legs and necks and distinctively curved bills. Saetas and water poppies (amapolas del agua), a rooted floating herb with showy yellow flowers, add color to the aquatic margins, while camalotes (water hyacinth) also appear in the channel. Coipos (large semi-aquatic rodents native to South America) rest on grass platforms along the banks, adding to the diversity of fauna a paddler is likely to encounter.

The overall character of the paddling experience is defined by the interplay of water, vegetation, and wildlife. The banks present a mix of wooded sections and open reed beds, and the numerous associated lagunas (lagoons) in the area expand the range of aquatic environments accessible from the arroyo. The combination of these habitats makes it a destination of interest primarily for nature observation, particularly birdwatching, alongside paddling.
