A special feature of the Paraná, one of the fastest running and longest rivers in the world, is that it runs between high cliffs. To the North of Rosario, upstream, the river opens up into a delta, reaching a width of up to fifty kilometers when it passes by the city.
Due to this characteristic of the river, hundreds of islands lie on its banks and enable visitors to enjoy large fine sandy beaches, thus offering a unique natural scenery for beholding or resting, and at the same time practice water sports along the channels.
