Termas de Chillán: the practical guide

Updated July 2026 · Written from Puerto Varas by Patagonia SimRacing

In the Andean foothills of Chile's Ñuble Region, at the foot of the Chillán volcano, the Nevados de Chillán ski resort shares a mountain with one of the country's oldest thermal complexes: snow up top, volcanically heated water down below — same hill. All around, the Ñuble National Reserve offers trails through native forest and lookouts onto the volcano, and down in the valley the city of Chillán delivers the culinary finale with its Denomination of Origin longaniza sausage and its historic market. Here's what to know before plotting your route between snow, hot springs and local flavor.

The must-sees

1. Termas de Chillán: hot springs of volcanic origin

The Termas de Chillán owe their existence to the same volcanic complex that crowns the area, the Nevados de Chillán: rain and meltwater heated deep underground by magma, surfacing already thermal. Bathing here goes back a long way — an oil painting by Chilean artist Onofre Jarpa, titled precisely "Termas de Chillán" and painted before 1901, now hangs in the National Museum of Fine Arts, testifying to how long this place has been a retreat. Today the hotel complex runs outdoor thermal pools with mountain views, a spa, and volcanic-mud treatments, and because it sits on the same hill as the ski resort, you can combine a morning on the snow with an afternoon in hot water on the same day.

2. Nevados de Chillán: Chile's largest ski resort

The Nevados de Chillán ski resort (known for decades simply as "Termas de Chillán") spreads its skiable terrain across several sectors linked by lifts, with a base near 1,800 m and runs climbing above 2,500 m. It's recognized as one of the most extensive in South America and, above all, for "El Otto," a run of about 13 km descending from the top to the base through araucaria and lenga forest — one of the longest on the continent. Because it sits on an active volcano, much of the appeal for more experienced skiers lies in off-piste skiing over volcanic ash, unlike the snow at other Chilean resorts. In a normal year the season runs June to October.

3. Valle Las Trancas: the gateway

On the road up to the hot springs and the ski resort, the village of Las Trancas concentrates cabins, hostels, restaurants and gear rental, and works as a base for those who'd rather not stay up at the thermal hotel. It's also the starting point for the Ñuble National Reserve and for spots like Valle Hermoso, with a direct view of the volcano. Outside the snow season, Las Trancas moves at a calmer pace, with hiking, horseback riding and the hot springs as the main draw.

4. Hiking in the Ñuble National Reserve and the Chillán volcano

The Ñuble National Reserve, managed by CONAF next to Las Trancas, protects a stretch of native araucaria, oak and lenga forest at the foot of the volcano. The short Los Pretiles trail, with its basalt column formations, is the most accessible and suitable for the whole family; for a longer walk, the trail to Laguna Fea pushes several hours through forest and open views of the cordillera. On clear days, the area's lookouts reward you with views of the Chillán Viejo volcano — intermittently active over recent decades — and the peaks known as Las Tres Marías.

5. Chillán: longaniza, the market and the Escuela México murals

Chillán, the base city about 80 km from the hot springs, is the birthplace of Bernardo O'Higgins, hero of Chile's independence, and one of the cities hit hardest by the 1939 earthquake — among the deadliest in the country's history — which explains much of its rebuilt architecture. After the quake, the government of Mexico donated the Escuela México, today a museum, with murals by Mexican muralists David Alfaro Siqueiros and Xavier Guerrero. On the flavor front, the longaniza de Chillán — a seasoned pork sausage with a Denomination of Origin granted in 2012 — is the local star, traditionally sold in the city's historic covered market alongside other regional products. The Ñuble Region also includes part of the Itata Valley, one of Chile's oldest wine valleys, known for its país and moscatel vines more than a century old.

Approximate prices (2026)

Ski and hot-spring prices change with the season, day of the week and how far ahead you book; confirm current rates and availability before traveling, especially during winter holidays.

How to get there and when to go

• By car from Santiago: Chillán is about 400 km (4.5–5 hours) down Ruta 5 Sur. From Chillán it's about 80 km on paved road to Las Trancas and the upper area with the hot springs.
• By bus or plane: regular buses run from Terminal de Buses Santiago (Alameda) to Chillán, and there are direct flights to Chillán's airport; from the city you'll need a rural shared van, taxi or rental car to get up to the springs.
• Snow season: June to October, with July and August bringing the most snow; check lift status before setting off.
• Hot springs and hiking season: the pools operate year-round; the trails of the Ñuble National Reserve are best enjoyed between November and April, when the path is clear of snow.
• Bookings: during winter holidays (July) and long weekends, reserve accommodation, ski passes and hot-spring tickets in advance.
