The Reloncaví Estuary, located in the Los Lagos region of Chile, is a remarkable fjord that serves as the natural gateway to Chilean Patagonia. Positioned northeast of the Seno de Reloncaví bay, it stands out for its breathtaking landscapes, exceptional biodiversity, and captivating local culture. More than just a tourist attraction, this site is essential for nature lovers and adventure seekers.

An exceptional geographical setting

The Reloncaví Estuary lies south of the port city of Puerto Montt, approximately 45 km away. It marks the transition between the Gulf of Ancud to the north and the fjords and channels of Patagonia to the south. This arm of the sea, stretching roughly 65 km long and 2 to 10 km wide, cuts deep into the land, surrounded by steep mountains covered in temperate forests.

It is here that the Petrohué River and the Puelo River complete their journey from Lake Todos los Santos, emptying their waters into the estuary. This mixture of fresh and salt water, characteristic of estuaries, creates a rich and diverse ecosystem conducive to countless forms of life.

A spectacular landscape

The Reloncaví Estuary is renowned for its grandiose scenery. It is bordered by imposing mountains and dominated by volcanic summits such as the Yates and Calbuco volcanoes, whose majestic silhouettes add a dramatic dimension to the region.

Near this estuary are various national parks and preserved natural areas, including:

• Cochamó Valley
• Llanquihue National Reserve
• Vicente Pérez Rosales National Park
• Hornopirén National Park
• Alerce Andino National Park

The estuary's waters range from emerald green to deep blue, depending on weather conditions and light. This color palette is enhanced by the striking contrast with the eternal snows of the surrounding peaks, creating panoramas that seem straight out of a postcard.

A rich and varied ecosystem

The Reloncaví Estuary is a sanctuary for biodiversity. Its mixture of fresh and salt water favors the presence of varied fauna, from marine species to terrestrial birds.

Among the most emblematic aquatic mammals of the estuary are sea lions, seals, Chilean dolphins, and otaries. It is sometimes possible to spot humpback whales, rorquals, and orcas.

Moreover, a wide variety of fish can be found in the Reloncaví Estuary waters, such as salmon, trout, hake, snook, puye, and others.

Marine birds are also abundant. Indeed, Chilean flamingos, cormorants, Magellanic oystercatchers, pelicans, herons, and gulls inhabit the shores and islands of the estuary. Near the estuary sits the Isla Mocha Natural Reserve, where various bird species can be observed in their natural habitat.

In the surrounding forests, it is not uncommon to encounter endemic species such as the pudu (a small deer), or even Chilean foxes.

The Reloncaví Estuary today

Although the Reloncaví Estuary is a natural paradise, it faces environmental challenges. The expansion of human activities, such as salmon farming, aquaculture, and tourism, exerts growing pressure on this fragile ecosystem.

Efforts are nonetheless being made to preserve this unique environment. Local and international organizations work to raise awareness among communities and visitors about the importance of conservation. Additionally, Chile has implemented regulations to protect sensitive natural areas, including national parks and marine reserves.
