Predelta National Park, National park in Diamante Department, Argentina
Predelta National Park is a protected area along the Parana River in Entre Rios province, Argentina, covering three islands shaped by wetlands, lagoons, and riverside forests. The terrain alternates between raised ridges and low-lying flood zones crossed by waterways.
The park was formally established by federal law in December 1991 and began operating in January 1992. Its creation was part of a national effort to protect the ecologically fragile zone at the start of the Parana Delta.
Fishing traditions have shaped how people relate to this place for generations, and those practices remain part of daily life here. In some areas of the park, you may see people fishing, keeping old habits alive along the riverbanks.
The park is reached from Diamante city through the La Jaula gateway to the south, via a paved road with clear signs. Sturdy footwear is a good idea since many paths can be muddy or wet after rain.
This park sits at the very point where the Parana Delta system begins, one of the largest river delta systems in the world, showing all its early formation stages in one place. The raised ridges here are built by river sediment and are still slowly growing, meaning the land itself continues to change.
