Predelta National Park: Introduction

Sun, 21 Jun 2026 00:00:00 GMT

This is where a continent's second-longest river starts to come undone.

Predelta National Park protects a small sample of this beginning, the upper edge of the vast Paraná Delta. It is the smallest national park in Argentina, but it guards one of the most dynamic landscapes on the continent, a place still actively building itself out of mud and water.

Predelta National Park: The Gateway to the Delta

Sun, 21 Jun 2026 00:00:00 GMT

Predelta is best understood as a threshold. Downstream, the delta widens for hundreds of kilometers, eventually fanning out near Buenos Aires into one of the great river mouths of the world, a labyrinth of islands and channels covering an area larger than many countries. What the...
