Full guide to Puerto Deseado →

Puerto Deseado is one of Patagonia's best-kept secrets for wildlife enthusiasts. This small fishing town on the Atlantic coast of Santa Cruz province sits at the mouth of the Deseado River estuary, a remarkable tidal inlet that creates a unique marine ecosystem teeming with life.

During summer (December to February), the estuary becomes a nursery for Commerson's dolphins, striking black-and-white cetaceans found only in southern South America. Rockhopper penguins nest on nearby Isla Pingüino, while Magellanic penguins establish colonies along the coast. The waters are alive with cormorants, sea lions, and occasionally even orcas.

The town itself is unpretentious and welcoming, with a working port atmosphere that gives visitors an authentic taste of coastal Patagonian life. Fresh seafood is abundant, and the local fishing fleet brings in spider crabs, mussels, and various fish species daily.

Summer brings warm temperatures and long days perfect for boat excursions through the estuary and visits to offshore islands. The Ría Deseado Natural Reserve protects the entire estuary system, making it one of the most important marine protected areas in Argentina. Darwin visited this area during his voyage on the Beagle, and the landscape remains largely unchanged since his time.
