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.
