Summer in Los Alerces National Park

Summer is the perfect season to explore Los Alerces National Park, a UNESCO World Heritage Site protecting 2,600-year-old alerce trees. Enjoy boat excursions across emerald lakes, forest hikes, pristine swimming, and ancient wilderness from December to February.

Los Alerces National Park is one of Patagonia's greatest natural treasures. Designated a UNESCO World Heritage Site in 2017, this park in Argentina's Chubut province protects some of the last remaining stands of Patagonian alerce trees (Fitzroya cupressoides) — ancient conifers that can live over 3,600 years, making them among the oldest living organisms on Earth. The park's 263,000 hectares encompass pristine lakes, Valdivian temperate rainforest, waterfalls, and snow-capped peaks.

Summer, from December through February, is the prime season for visiting Los Alerces. The park's boat excursion across Lago Menéndez to the ancient alerce grove — the highlight experience — operates only during the warmer months. Temperatures reach comfortable highs of 22-26°C, trails are snow-free and accessible, and the lakes warm enough for swimming in sheltered spots.

The park centers around a chain of interconnected lakes — Futalaufquen, Verde, Menéndez, and Rivadavia — each a different shade of emerald and turquoise. Lago Futalaufquen is the most accessible, with a road running along its eastern shore providing access to campgrounds, trailheads, and the park's administrative center. From the lake's southern end, a boat and trail combination leads deep into the park's interior to reach El Abuelo (The Grandfather), a 2,600-year-old alerce tree of breathtaking size.

Accessed from the gateway city of Esquel (50km), the park is best explored with a rental car, which allows you to drive the scenic lakeshore road, access multiple trailheads, and time your visit to the boat excursion perfectly.

Weather Overview

Avg High

24°C

Avg Low

8°C

Precipitation

Summer is the driest season, though the Valdivian forest microclimate means rain is always possible. Expect about 30-50mm per month with occasional afternoon showers.

Wind

Generally calm within the forested valleys. Lake surfaces can develop afternoon chop from valley breezes, which may affect boat excursions on windy days.

Daylight

Long days with 16-17 hours of daylight, providing ample time for boat excursions, hikes, and lakeside relaxation.

Summer in Los Alerces is warm and pleasant in the valleys, with cooler conditions in the dense forest interior and at higher elevations. Clear mornings often give way to buildups of afternoon clouds. The forest maintains its own humid microclimate — even on sunny days, the deep forest floor can be damp and cool. Layering is always wise.

Activities

Available Activities

Boat Excursion to Ancient Alerce

The park's signature experience: a boat crosses Lago Menéndez, followed by a guided forest walk to El Abuelo, a 2,600-year-old, 57-meter-tall alerce tree. The full excursion takes most of the day and operates only in summer. Book in advance.

Lago Futalaufquen Swimming and Beaches

The lake's sheltered bays and beaches warm enough in summer for swimming. Playa Desemboque is a popular spot. The crystal-clear water surrounded by forest creates a spectacular swimming environment.

Forest Hiking

Numerous trails wind through the park ranging from easy lakeside walks to challenging mountain ascents. Highlights include the Pinturas Rupestres trail, Cinco Saltos waterfall hike, and the trek to Lago Krüger.

Kayaking

Paddle on Lago Futalaufquen and connecting waterways. The calm morning waters, forested shores, and mountain reflections make for extraordinary kayaking. Rentals available at the lake.

Fly Fishing

The park's lakes and the Rivadavia River between lakes offer excellent trout fishing. Brown and rainbow trout thrive in these pristine waters. A fishing license is required.

Wildlife and Bird Watching

The park is home to the endangered huemul deer, pudú (world's smallest deer), and the Magellanic woodpecker. Summer's longer days increase wildlife sighting opportunities.

Not Available This Season

The boat excursion to the ancient alerce runs only in summer — confirm exact datesSome higher-altitude trails may be snow-affected in early December

Accommodation

The park has several organized campgrounds along Lago Futalaufquen, ranging from basic to semi-serviced sites with hot showers. A few hosterías and cabañas within the park offer more comfortable stays. Esquel (50km) provides a wider range of hotels, hostels, and dining. Park accommodation is limited and fills quickly in January — reserve well ahead.

Crowds & Tourism

The park sees moderate visitation in summer, much less than Nahuel Huapi or Los Glaciares. The boat excursion to the ancient alerce is the most popular activity and can sell out — book days ahead. Campgrounds near the main beach fill on weekends and holidays. But the park's size and trail network mean solitude is easily found beyond the main areas.

Pricing

National park entrance fees are reasonable. The boat excursion to the ancient alerce is the most significant expense at approximately $50-80 USD. Camping is affordable. Fishing licenses are extra. Esquel provides good-value dining and accommodation. Overall, this is one of the more affordable UNESCO World Heritage experiences in Patagonia. Budget $70-120 USD per day.

Driving Conditions

Important for car rental travelers

The main park road along Lago Futalaufquen is partly paved and partly well-maintained gravel. It's accessible by standard vehicles in summer. The road from Esquel to the park entrance is paved. A rental car from Esquel is the most convenient way to explore, allowing you to access different trailheads and campgrounds throughout the day. Some secondary park roads may require higher clearance.

Frequently Asked Questions

How old are the alerce trees?

The most famous tree in the park, El Abuelo (The Grandfather), is approximately 2,600 years old. The species Fitzroya cupressoides can live over 3,600 years, making alerces the second-longest-lived tree species on Earth after bristlecone pines. They can grow up to 60 meters tall and 5 meters in diameter.

How do I book the boat excursion to the ancient alerce?

The excursion departs from Puerto Chucao on the southern end of Lago Menéndez. Book through tour operators in Esquel or at the park's information center. In January, book several days ahead. The full excursion takes about 7-8 hours including the boat crossing and guided forest walk.

Can I visit the park without a car?

It's possible via organized tours from Esquel, but a rental car provides much more flexibility. The park is spread along a 40km lake shore road, and having your own vehicle lets you access different areas, trailheads, and adjust plans based on weather.

Is camping the only option inside the park?

No, there are a few hosterías and cabañas within the park, though they are limited in number and book out early in summer. Camping is the most readily available option with several campgrounds along the lake. Esquel offers the full range of accommodation 50km away.

What makes Los Alerces a UNESCO World Heritage Site?

The park was inscribed in 2017 for its outstanding natural values, primarily the ancient alerce forest ecosystem. The alerces are living relics of the Gondwanan forests that covered the southern hemisphere millions of years ago. The park also protects pristine Valdivian temperate rainforest and glacial lake systems.
