Puyehue National Park: Volcanoes, Rainforest and Hot Springs

Puyehue National Park covers 107,000 hectares of Andean rainforest, active volcanic terrain, and geothermal springs just 80 km east of Osorno. The park's centerpiece, the Puyehue-Cordón Caulle volcanic complex, erupted violently in 2011, sending an ash cloud 12 km into the sky. Entry to the main trails is free, and the park is open daily from 9:00 to 17:30. Most visitors base themselves in Osorno or the small town of Entre Lagos, 16 km from the western entrance.

Getting There and Orientation

By Car from Osorno

The drive from Osorno to the park's main sectors takes about 1 hour and 15 minutes along Route 215, a fully paved international highway that continues to the Argentine border at Cardenal Samoré Pass. At kilometer 76, a signed turnoff leads to the U-485 variant, which climbs 18 km to Aguas Calientes and Antillanca. That final stretch is gravel — narrow and winding in places, so allow 30 minutes and drive carefully, especially after rain. Fuel up in Osorno or Entre Lagos; there are no gas stations inside the park.

By Bus

Buses Puyehue runs frequent services from Osorno's rural terminal (Errázuriz 1300) to the park entrance and the Termas de Puyehue hotel, with departures roughly every hour and fares under $5. The trip takes about 2 hours. From Puerto Montt, you must first transfer in Osorno. If you're coming from Bariloche, Andes Mar and Río de la Plata coaches stop along Route 215 near the park.

The Three Sectors

The park is divided into three main areas. Aguas Calientes, closest to the highway, holds the ranger office and the hot springs. Antillanca, at the end of the gravel road, is the ski and mountain resort base. Anticura, 22 km east of Aguas Calientes along Route 215, is the quietest sector, with forest trails and waterfalls. Most day-trippers crowd Aguas Calientes and Antillanca; Anticura tends to be less visited, a detail that matters if you want solitude on the trail.

What to See and Do

Volcanoes and Geothermal Features

The Puyehue volcano rises to 2,236 meters, and the surrounding Cordón Caulle is one of the most active volcanic zones in Chile. The 2011 eruption reshaped parts of the landscape and left ash deposits still visible on the slopes. Los Baños hot spring, on a river terrace near the volcano's northwest flank, has pools ranging from 43°C to 70°C. Steam vents and fumaroles appear in several spots, including the El Azufral crater area. Note that you cannot approach an active crater — the park entrance does not grant access to volcanic vents.

Hiking Trails

Trails range from short forest walks to a demanding summit route. The climb to Puyehue's summit covers roughly 16–21 km round trip with 1,700–1,950 meters of elevation gain, taking 10–11 hours — a serious full-day effort for fit hikers. In winter, crampons, an ice axe, and a helmet are necessary on exposed sections. Easier options include the waterfall trails at Anticura and the loop paths near Aguas Calientes. Three trails are concessioned and charge their own fees: El Indio, Repucura, and La Princesa. For long-distance routes, you must request authorization from the park administrator in advance.

Hot Springs and Winter Sports

The Termas de Puyehue spa, near the park's western edge, has been operating for decades and includes thermal pools and mud baths. The Gran Hotel Termas de Puyehue accommodates 350 guests and has its own thermal pool pavilion. At Antillanca, a ski area operates in winter (June–September), with lifts on the slopes of the Casablanca volcano. Summer brings hikers and climbers instead.

Lakes and Fishing

Lago Puyehue, bordering the park, offers kayaking and recreational fishing. A short detour off Route 215 toward Puerto Chalupa on Lago Rupanco leads to a beach popular with local anglers. The rivers and lakes here hold trout and salmon, and local families along the shore offer rural tourism experiences and home-cooked food.

Practical Information

Hours, Fees and Rules

The park is open Monday to Sunday, 9:00 to 17:30, year-round. General entry to the park and its main trails is free — no reservation is needed. The concessioned trails (El Indio, Repucura, La Princesa) charge separate fees set by each operator. Fees and schedules can change due to snow, ice, rain, or maintenance, so check the CONAF website before you go. Rangers are stationed at Aguas Calientes and Anticura throughout the year.

Best Time to Visit

December to March is the driest period and the best window for hiking and volcano views. Winter (June–September) suits skiers and those prepared for snow. Rain is possible at any time of year — this is temperate rainforest, after all. Pack a lightweight waterproof layer, warm clothing, and footwear that handles mud. Morning light is best for photography, and afternoon clouds often hide the peaks.

Safety and Etiquette

Weather changes fast in the Andes. Tell someone your route before setting out, carry enough water, and be aware that the volcano summit route crosses a river that can become impassable during spring snowmelt. Do not enter closed areas or approach active fumaroles. For emergencies, contact the park administrator at +56 9 93266653.
