Parque Nacional Huerquehue
Three jade-green lakes linked by trails through ancient araucaria forest, each pool clearer than the last.
Mist pools between araucaria canopies as the trail climbs through forest that looks unchanged since the Cretaceous. Each lake reveals itself suddenly — a flash of jade green through the branches, water so clear you can count submerged branches five metres below. Parque Nacional Huerquehue in Chile's Araucanía Region strings three emerald lakes along a single trail through 900-year-old monkey puzzle forest.
The Los Lagos trail links Lago Tinquilco, Lago Chico, and Lago Verde in under five hours, the araucaria canopy forming a prehistoric tunnel over the path. On clear days the trail's high points deliver simultaneous views of Volcán Villarrica and Volcán Lanín across the Argentine border — two active cones in a single sightline. In January and February the smaller lakes warm enough for swimming, their clarity revealing a submerged world of ancient branches and volcanic rock. Dawn mist sits in the valley between the lakes until mid-morning, transforming the forest into layered planes of fog and filtered light that shift character every ten minutes. The proximity to Pucón — just 35 kilometres — makes Huerquehue one of the most accessible ancient forests in southern Chile.
Couple
The trail's moderate difficulty and the reward of swimming in jade-green volcanic lakes make this a day hike that feels like an expedition. Pack piñones and a picnic — the lakeshore lunch spots are worth the climb.
Family
Older children handle the trail comfortably, and the lakes at the top provide the payoff every family hike needs — warm enough to swim, clear enough to snorkel, and ringed by trees that look like dinosaur props.
Friends
The hike-swim-beer progression is perfectly calibrated. Three lakes, one trail, and Pucón's microbreweries waiting at the bottom — a day that earns every post-hike sopaipilla.
- The Los Lagos trail links three emerald lakes through 900-year-old araucaria forest in under 5 hours — the tree canopy forms a prehistoric tunnel over the path.
- On clear days the trail's high points offer simultaneous views of Volcán Villarrica (Chile) and Volcán Lanín (Argentina) — two active volcanoes in one sightline.
- The smaller lakes are warm enough to swim in during January and February — water clarity reveals submerged araucaria branches 5 metres below the surface.
- Dawn mist sits in the valley between the lakes until 9am — early hikers walk through layered fog and light that changes character every 10 minutes.
Piñones gathered from the forest floor and boiled at the lakeshore — the trail's best snack.
