Alerce Andino Overview

Alerce Andino National Park, or Parque Nacional Alerce Andino in Spanish, is a protected natural area in southern Chile, covering approximately 386 square miles (1,571 square kilometers).

Located in the Los Lagos Region, the park is part of the vast Temperate Rainforest of the Southern Andes and is known for preserving one of the last remaining ancient alerce tree forests. These towering trees, which can live for over 3,000 years, are one of the park’s defining features, giving the landscape a mystical and primeval feel.

The park is part of the larger Patagonian Biosphere Reserve and sits near the city of Puerto Montt, serving as a gateway to Chilean Patagonia.

The terrain of Alerce Andino National Park is dominated by steep mountains, deep valleys, and numerous pristine lakes and rivers. The park lies within the Andes and features an intricate network of fjords and channels, shaped by glacial activity over thousands of years.

Some of the most notable natural features include Lake Chapo and the Sargazo and Chaiquenes lagoons, offering stunning reflections of the surrounding peaks. The dense Valdivian temperate rainforest blankets much of the park, filled with not only ancient alerce trees but also other native species such as coigüe, tepa, and mañío. Mosses and ferns thrive in the humid environment, adding to the lush and untouched appearance of the landscape.

Alerce Andino National Park is home to a diverse array of wildlife, with mammals and birds that are typical of Chilean Patagonia. Among the most notable species are the elusive puma, the small but rare pudú deer, and the monito del monte, a tiny marsupial that is considered a living fossil.

Birdwatchers can spot the striking Magellanic woodpecker, Chilean hawks, and the Andean condor soaring high above the cliffs. The waterways and forests also support amphibians such as the Darwin’s frog, an unusual species known for its unique reproductive behavior. The biodiversity of the park is one of its key ecological treasures, drawing both scientists and nature enthusiasts.

Visitors to the park often come for its well-maintained hiking trails, which offer immersive experiences through the dense forest and alongside crystal-clear lakes. One of the most popular trails leads to the Alerce Milenario, a massive alerce tree estimated to be over 3,000 years old. Another rewarding hike takes adventurers to the Chaicas River waterfall, where water cascades through lush greenery into a serene pool below.

Kayaking on the park’s lakes and rivers allows for a peaceful yet adventurous exploration of the region’s remote beauty. The park also attracts photographers, wildlife watchers, and those seeking a quiet retreat into nature.

Despite its protected status, Alerce Andino National Park faces conservation challenges, particularly concerning illegal logging and climate change. Alerce trees, highly valued for their durable wood, have historically been overexploited, making conservation efforts critical for their survival.

However, Chilean authorities have implemented strict protections, and ongoing reforestation projects aim to restore damaged areas. The park’s inclusion in the Patagonian Biosphere Reserve has helped secure funding and international support for its preservation. As tourism grows, sustainable visitor practices are increasingly promoted to ensure that the fragile ecosystem remains intact for future generations.

Alerce Andino National Park Highlights

Popular

Alerce Andino National Park, located in the Los Lagos Region of southern Chile, is a breathtaking landscape of ancient forests, pristine rivers, and glacial lakes. The park is named after the majestic alerce tree (Fitzroya cupressoides), one of the oldest living tree species in the world, some of which are over 3,500 years old. This dense temperate rainforest provides a sanctuary for many unique and endemic species, making it one of Chile’s most ecologically significant conservation areas.

Pudu (Pudu puda)
The pudu is the world’s smallest deer, standing only about 40 cm (16 inches) tall at the shoulder. It thrives in the dense undergrowth of Alerce Andino’s forests, feeding on leaves, fruits, and bark while avoiding predators like pumas.

Puma (Puma concolor)
As the top predator of the park, the puma plays a crucial role in maintaining the balance of the ecosystem. It preys on pudus, rodents, and other small mammals, using stealth and power to hunt in the thick vegetation.

Kodkod (Leopardus guigna)
Also known as the güiña, this small and elusive wild cat is endemic to the forests of Chile and Argentina. It is an excellent climber and primarily hunts birds, rodents, and insects in the dense rainforest.

Darwin’s Fox (Lycalopex fulvipes)
One of the rarest canids in the world, Darwin’s fox is endemic to southern Chile. It is nocturnal and highly elusive, feeding on small mammals, birds, and fruits in the dense temperate forests.

South American Coati (Nasua nasua)
A social and curious mammal, the South American coati is often seen in groups foraging through the park’s forests. It uses its long snout to dig for insects, fruits, and small vertebrates.

Southern River Otter (Lontra provocax)
This endangered otter species thrives in the park’s rivers and lakes. It is an excellent swimmer, preying on fish and crustaceans while relying on clean freshwater habitats to survive.

Huemul (Hippocamelus bisulcus)
An emblematic species of Chile, the huemul is an endangered deer that prefers remote and rugged terrain. Though rarely seen, it finds refuge in the park’s high-altitude forests and steep valleys.

Andean White-eared Opossum (Didelphis pernigra)
A nocturnal marsupial, this opossum is an important seed disperser in Alerce Andino’s ecosystem. It feeds on fruits, insects, and small vertebrates, playing a key role in maintaining forest health.

Magellanic Tuco-tuco (Ctenomys magellanicus)
This small, burrowing rodent is adapted to the cool, wet climate of southern Chile. It spends most of its life underground, where it feeds on roots and grasses.

Black-necked Swamp Turtle (Acanthochelys spixii)
An uncommon reptile in the park, this freshwater turtle inhabits slow-moving rivers and marshes. It feeds on aquatic plants and small invertebrates while relying on clean water sources.
