Ruta de las Termas Geométricas Villarrica
Volcanic hot springs through ancient araucaria forests
This 34-kilometer mountain track cuts through dense araucaria forests on Volcán Villarrica’s eastern flanks, connecting the main highway to the geometric hot springs complex built into a narrow gorge. The route follows old logging roads past Coñaripe village, climbing through sections of deep volcanic ash that can trap unprepared vehicles, especially after recent eruptions. Two major river crossings at Río Tancura require careful navigation during snowmelt season.
Moderate difficulty demands high-clearance 4WD and recovery gear for the ash sections. Best accessed May through September when river levels drop and volcanic activity typically decreases. No permits required but fuel up in Pucón — there’s nothing once you commit to the forest roads. The payoff is soaking in architect-designed thermal pools carved into volcanic rock, plus camping among thousand-year-old monkey puzzle trees that survived multiple eruptions.

Frequently asked questions
Can a stock Jeep Wrangler or 4Runner handle this trail, or do I need a lifted rig?
A stock 4WD high-clearance vehicle like a Wrangler or 4Runner can manage this trail, but the volcanic ash sections get soft and unpredictable — all-terrain tires and lockers help significantly. Lifted rigs have an easier time on the river fords. A bone-stock crossover SUV is a no-go.
When is this trail actually drivable — does it close in summer or winter?
Best season is May through September, which is Chile's fall and winter — counterintuitive if you're coming from the Northern Hemisphere. Summer (December–February) brings dry volcanic ash that turns the track into a loose, rutted mess and fire risk increases around Villarrica. Spring snowmelt can also spike the river ford levels unpredictably.
Do I need a permit to drive this route, and is there a fee to access Termas Geométricas?
The trail itself falls under CONAF jurisdiction — no separate driving permit is required, but check current CONAF regulations before you go as access rules around Villarrica National Park boundaries can shift. Termas Geométricas hot springs charges a separate entry fee (around 30,000–40,000 CLP as of recent visits) if you're going in to soak.
How serious are the river fords — can I cross them solo or do I need a spotter?
There are multiple fords on this route fed by Andean snowmelt and volcanic runoff, so depth varies a lot by season and recent rainfall — knee-deep is common, thigh-deep is possible after heavy rain. Solo crossing is doable in favorable conditions, but always walk the ford first to check the bottom and current before you commit. A recovery rope and a buddy rig are smart given zero cell service on the entire trail.
Is there anywhere to get gas or supplies near the trailhead, and how far is it from Pucón?
Pucón is your last stop for fuel, food, and anything mechanical — fuel up there without exception, as there's nothing once you leave town. The trailhead is roughly 20–25 km from Pucón, but roads in the area slow you down considerably, so budget 45–60 minutes from town to the start.
