Rising 2,847 meters over the eastern horizon, Villarrica volcano is the reason the town has a name and the reason it watches the sky. The Mapuche called it Rucapillán, the house of the spirit, and they were not speaking metaphorically. This is a stratovolcano that holds an open lava lake inside its crater, one of only a handful on Earth known to sustain an active lava lake, glowing intermittently from within. It is the most active volcano in Chile, and it does not announce itself politely. In 2015 it threw a fountain of fire a kilometer into the night, and it erupted again in 2025. People here live with that knowledge the way coastal towns live with the tide: as a fact of the place, neither denied nor dwelt upon.

Walk the streets and read the shop signs, and the names tell a story the architecture confirms. Beginning around 1850, waves of German and Dutch immigrants settled this corner of Araucanía, drawn by a Chilean government eager to populate its southern frontier. They built in wood, steep-roofed against the rain, and they brought dairy cattle, grain, and the methodical farming that still anchors the local economy. The result is a town that feels transplanted: a slice of Central Europe set down beside a Patagonian lake, where a Schmidt or a Müller might pour you coffee a short drive from a Mapuche craft market selling woven wool blankets and carved wood.

The same volcanic plumbing that makes the mountain dangerous makes the surrounding valleys a bather's paradise. Geothermal springs surface all through the area, each at its own temperature, and locals know them like regulars know bars. Coñaripe runs at a gentle 48 degrees Celsius. Palguín climbs to 57. Liquiñe, the hottest, reaches a scalding 87, hot enough to demand respect. The most beloved are Los Pozones, where pools step down a forested gorge, and the Termas Geométricas, a designed retreat of red walkways threading between steaming basins. You soak in water that fell as rain and was warmed by the same fire that lights the crater above.

After the drama of the mountain, Lake Villarrica offers the antidote. Its shores sit low, between 200 and 500 meters above sea level, and in the dry summer months of December through February the water warms enough for swimming and sunbathing on black volcanic-sand beaches. The rivers feeding the basin, the Toltén, the Trancura, the Voipir, carry rafters and fly fishermen chasing trout. Beyond the water, forests of Araucaria, the ancient monkey puzzle tree sacred to the Mapuche, climb toward Huerquehue National Park, where Magellanic woodpeckers hammer at trunks that predate every name on every shop sign in town.

Villarrica has always lived a little in the shadow of its flashier neighbor. Pucón, twenty minutes east along the lake, hoards the backpackers, the nightlife, and the adventure-agency hard sell, while Villarrica keeps the working rhythm of a real town: the dairy trucks, the grain harvest, the families who have farmed here for generations. That is its quiet advantage. You can still book the same volcano climbs, the same trips to Huerquehue and the hot springs, through outfitters like Politur, then return each evening to a place that does not feel staged for visitors. Getting here is simple enough, an overnight bus from Santiago or a short flight to Temuco and an hour's drive south, and the reward is the lake district experienced at the pace of the people who actually live it, with the volcano keeping its patient watch over both towns at once.
