Full guide to Los Alerces National Park →

Los Alerces National Park, inscribed as a UNESCO World Heritage Site in 2017, protects one of the last remaining old-growth Patagonian Andean forests. The park's star inhabitants are the ancient alerce trees (Fitzroya cupressoides) — some over 2,600 years old, making them among the oldest living organisms on Earth.

Autumn, from March through May, reveals the park at its most dramatic. While the alerce trees themselves are evergreen, the surrounding deciduous forests of lenga, ñire, and radal trees erupt in brilliant fall colors — crimson, gold, copper, and amber — creating a stunning mosaic against the emerald backdrop of the ancient conifers and the turquoise waters of the park's numerous lakes.

The park encompasses over 263,000 hectares of pristine Andean Patagonian forest, centered around a chain of interconnected glacial lakes including Futalaufquen, Menéndez, Rivadavia, and Krüger. These lakes, fed by glacial melt and rainfall, display extraordinary turquoise and emerald hues that intensify when surrounded by autumn foliage.

March offers the warmest conditions and most available services, including the boat excursion across Lago Menéndez to the ancient alerce forest — one of the park's most celebrated experiences. April brings peak foliage color and a contemplative atmosphere as visitor numbers drop. By May, the park grows quiet, with some services closing but the main trails and campgrounds remaining accessible.

Accessible from the town of Esquel (40km), Los Alerces rewards visitors who make the autumn journey with an experience that combines botanical wonder, geological beauty, and profound natural silence — a fitting setting for trees that have witnessed millennia of Patagonian seasons.

Accommodation

Within the park, options include organized campgrounds and a few cabañas near Lago Futalaufquen. The lakeside Hostería Futalaufquen offers comfortable rooms. Most visitors base themselves in Esquel or Trevelin, which have wider options. Autumn brings lower rates everywhere (25-40% off summer). Park campgrounds are functional but increasingly cold from April — bring proper gear.

Crowds & Tourism

Los Alerces sees far fewer visitors than Nahuel Huapi or Lanín national parks, and autumn reduces numbers further. March brings modest visitor flow, while April and May offer near-solitude on the trails. The boat excursion to the alerce forest runs with smaller groups, making it more personal and enjoyable.

Pricing

Autumn offers the best value, with accommodation 25-40% below summer rates. Park entrance fees are standard year-round. The alerce boat excursion maintains its regular price but with guaranteed availability. Guided fishing excursions may offer autumn discounts. Overall, this is one of the most affordable times to experience a UNESCO site in Patagonia.
