Summer in Pumalín Park

Summer is the ideal season for Pumalín Park, one of South America's great conservation triumphs. Hike through ancient alerce forests, soak in volcanic hot springs, explore the Chaitén volcano crater, and drive the northern Carretera Austral from December to February.

Pumalín Park (officially Parque Nacional Pumalín Douglas Tompkins) is a conservation masterpiece. Originally created as a private nature reserve by American philanthropist Doug Tompkins and later donated to the Chilean state in 2018, this 402,000-hectare park stretches from the Pacific coast to the Andes, protecting vast swaths of ancient Valdivian temperate rainforest, alerce groves, volcanic peaks, and pristine fjords.

Summer from December through February is the only practical season for most visitors. The park's notorious rainfall — among the highest in Chile — eases somewhat in summer, trails become accessible, ferry services to Caleta Gonzalo operate at full schedule, and the region's hot springs reach their most comfortable ambient temperatures. Even in summer, expect rain, but you'll also get glorious stretches of sunshine that illuminate the primeval forest in extraordinary green light.

The park straddles the Carretera Austral near its northern end, making it a natural first or last stop for road trippers. From the northern entrance at Caleta Gonzalo (reached by ferry from Hornopirén) to the town of Chaitén at the southern end, the route through the park is among the most dramatic stretches of the entire highway. Waterfalls cascade from forested cliffs, fiords penetrate the coastline, and the scarred Chaitén volcano — which erupted violently in 2008 — looms over the landscape.

The park infrastructure, a legacy of the Tompkins Conservation vision, is remarkably well-designed. Campgrounds, trail systems, cabins, and a café at Caleta Gonzalo blend seamlessly into the environment. A rental car is essential for navigating the Carretera Austral through the park.

Weather Overview

Avg High

18°C

Avg Low

9°C

Precipitation

Pumalín is one of Chile's wettest areas, receiving 3,000-5,000mm annually. Summer is the driest period but still wet — expect 100-200mm per month. Rain gear is essential at all times.

Wind

Winds are moderate in the sheltered forest valleys but can be strong on the coast and exposed ridges. The fjord geography channels wind through certain corridors.

Daylight

Long days with 16-17 hours of daylight, though cloud cover and rain can reduce effective sunlight hours.

Summer in Pumalín is mild and green. Expect a mix of rain, cloud, and sunshine — sometimes all within the same hour. When the sun breaks through, the forest glows with an almost supernatural intensity. Temperatures are cool to mild; you'll rarely feel hot. The persistent moisture creates a lush, almost tropical feel despite the latitude.

Activities

Available Activities

Alerce Forest Trails

Walk among giant alerce trees — some over 3,000 years old and 5 meters in diameter — on well-maintained boardwalk trails. The Sendero Alerce trail near Caleta Gonzalo and the Sendero Los Alerces trail are the most accessible.

Chaitén Volcano Hike

Trek to the rim of Chaitén volcano, which erupted dramatically in 2008. The trail passes through devastated forest regenerating around the lava dome. A surreal and powerful landscape that shows nature's destructive and regenerative power.

Volcanic Hot Springs

Several natural hot springs in the park offer soaking in volcanic-heated waters surrounded by temperate rainforest. The Termas El Amarillo are the most developed and accessible.

Cascadas Waterfall Hikes

Multiple short trails lead to dramatic waterfalls fed by the park's abundant rainfall. The Sendero Cascadas trail near Caleta Gonzalo features a series of cascades through dense forest.

Carretera Austral Driving

The stretch of Carretera Austral through the park is among the most dramatic of the entire highway — clinging to fiord edges, tunneling through forest, and crossing rivers. Summer offers the best driving conditions.

Kayaking Fjords

Guided kayak excursions explore the park's pristine fjords and coastline, paddling past sea lion colonies, waterfalls cascading directly into the ocean, and towering forested cliffs.

Not Available This Season

Some trails may be closed for maintenance or weather damage — check at park entrancesFerry schedules to Caleta Gonzalo may be affected by bad weather

Accommodation

The park has beautifully designed campgrounds at Caleta Gonzalo, Río Gonzalo, and other locations. Basic but charming cabañas are available near Caleta Gonzalo. The café at Caleta Gonzalo offers meals and provisions. Chaitén at the park's southern end has hostels, hotels, and restaurants. All park accommodation should be booked ahead in January.

Crowds & Tourism

Pumalín sees moderate summer tourism concentrated along the main Carretera Austral corridor. Caleta Gonzalo and the most popular trailheads can be busy when ferries arrive. However, the park's vast size and the region's remoteness mean it never feels crowded. Many trails offer complete solitude even in peak season.

Pricing

Park entry is free (national park). Camping fees are modest. The café and cabins at Caleta Gonzalo are reasonably priced. The main expenses are car rental, fuel, and ferry crossings. The ferry from Hornopirén to Caleta Gonzalo should be booked well in advance for summer travel. Budget $70-120 USD per day.

Driving Conditions

Important for car rental travelers

The Carretera Austral through Pumalín is partly paved and partly gravel. Summer provides the best conditions, but the road can be narrow, winding, and slippery after rain. A high-clearance vehicle is recommended; 4x4 is ideal for secondary roads. The ferry from Hornopirén to Caleta Gonzalo carries vehicles — book ahead in summer. From the south, the road from Chaitén into the park is accessible. Always carry extra fuel as stations are sparse.

Events & Festivals

Conservation Education Programs

Frequently Asked Questions

How do I reach Pumalín Park?

From the north, take the ferry from Hornopirén to Caleta Gonzalo (book ahead for vehicles in summer). From the south, drive the Carretera Austral from Chaitén. Both routes require a car. The nearest airports are Puerto Montt and Chaitén (small aircraft).

Do I need to book the ferry in advance?

Yes, especially for vehicles in summer. The Naviera Austral ferry from Hornopirén to Caleta Gonzalo fills up quickly in January. Foot passengers have more flexibility, but car spots should be reserved weeks or months ahead.

Who was Doug Tompkins?

Douglas Tompkins was the co-founder of The North Face and Esprit clothing brands. He and his wife Kristine dedicated their fortune to conservation in Chilean and Argentine Patagonia. Pumalín was their flagship project, eventually donated to Chile as a national park in 2018, creating the Route of Parks network.

How rainy is it really in summer?

Expect rain on at least half the days, sometimes more. However, the rain often comes in bursts between sunny periods. With good rain gear and the right attitude, the wet conditions are manageable and the forest is at its most magical when mist weaves through the ancient trees.

Can I camp in the park?

Yes, the park has several well-designed campgrounds with sheltered cooking areas, composting toilets, and cleared tent platforms. The infrastructure is excellent by wilderness standards. Bring warm, waterproof gear — night temperatures drop and rain is likely.
