Termas Geométricas: Complete Guide + Honest Review 2025

So you leave Pucón, hit a bumpy gravel road, dust swirling behind every car, and before you know it you’re parking on the side of a volcano. The drive itself feels endless, but it ends with the perfect reward: overheating and undercooling at Termas Geométricas.

This is my personal take on one of the most iconic hot springs in Chile.

After visiting Parque Termal Botánico, I was hooked. I wanted more hot springs, but wilder, the kind where you’re surrounded by forest, hearing birdsong and rushing streams, with freezing waterfalls crashing beside steaming pools. And yes, no internet connection, which honestly makes it even better.

When we finally arrived at Termas Geométricas, my first thought was: do the people working here actually make this crazy drive every single day?

My Termas Geométricas Review

It’s hard to put Termas Geométricas into words because it’s even more beautiful than the photos could ever show. For me, it’s probably the #1 place in Chile where human design blends perfectly with wild nature, those red walkways don’t feel artificial at all, they feel like they’ve always been there.

Then came the pools. The cold pool was way colder than I ever imagined (think glacier water), and the hot pool was way hotter than expected, stepping into 46° feels like your skin is about to melt, but in the best possible way.

What I loved most was the space. With so many pools spread out, it never felt crowded or overwhelming. Add in the forest setting, the drive through lakes and volcanoes, and the genuinely kind staff welcoming you at the entrance, the whole experience felt special from start to finish.

Honestly? One of my funnest memories in Chile.

The layout

Imagine stepping into the forest and suddenly finding a bright red wooden walkway leading you deeper between trees, rocks, and streams. That’s Termas Geométricas. The entire hot springs complex is connected by these long boardwalks, stretching almost 450 meters, with pools branching off on both sides.

As you walk along, you’ll pass steaming pools of different shapes and sizes — some tucked in quiet corners, others right next to the sound of rushing water. Halfway through, there’s even a freezing waterfall cutting through the middle of it all. At the very top, the path ends at a natural ice-cold pool fed straight from the mountain.

The design makes it feel like an adventure trail rather than a spa: you wander, discover, and choose your own spot to relax. It’s part wild nature, part geometric design, and completely unique.

What does Termas Geométricas mean?

The name isn’t random, it actually makes sense once you see the place.

Termas = Hot springs (Spanish)
Geométricas = Geometric (Spanish)

Why “geometric”?

The pools are connected by a long red wooden walkway, built in straight lines and sharp angles.
Everything feels designed around geometry, contrasting with the wild natural setting.
The architect 'Germán del Sol' wanted to blend human design with nature, and that’s where the name comes from.

So basically: Geometric Hot Springs.

What should I bring if I go to the hot springs?

Pack light, but don’t forget the essentials, it makes your visit way more comfortable:

Swimwear – obvious, but easy to forget if you come straight from hiking.
Towel – they rent them, but bringing your own is cheaper and nicer.
Flip-flops or sandals – the red wooden walkways get slippery (and sometimes hot).
Water bottle – the hot pools dehydrate you fast.
Cash – small shops or the entrance sometimes prefer it, especially if cards act up.
Plastic bag or dry bag – for your wet towel and swimwear afterwards.
Warm layers – once you get out of the water, the mountain air is chilly.
Snacks – especially something salty, since you’ll sweat a lot. There’s a café on-site, but it’s a little bit pricey and the options are limited.
Phone pouch or waterproof case – if you plan on taking photos without stressing about dropping it.

Optional but nice to have:

Hair tie or cap – keeps your hair from soaking in the mineral water all day.
Light rain jacket – it’s the south of Chile, sudden rain showers are normal.

💡 Lockers are available to keep your things safe, just note you’ll need to leave an ID card or even your glasses as a deposit for the key.

What are the facilities at Termas Geométricas?

Termas Geométricas has everything you need for an amazing experience at one of the most iconic hot springs in Chile:

Changing rooms – simple but practical, with benches and hooks.
Lockers – keep your stuff safe (you’ll leave an ID card or glasses as a deposit for the key).
Food & drinks – there’s a small café/snack bar where you can grab tea, coffee, or something light to eat.
Walkways & design – the long red wooden walkways are more than just paths; they’re part of the experience, connecting all the pools and giving the place its unique “geometric” character.

So while it’s all pretty minimal, the mix of forest, hot springs, and clever design is exactly what makes Termas Geométricas special.

How long should you stay sitting in thermal waters?

It’s tempting to sink in for hours, but pacing yourself makes the experience much better (and safer):

Recommended time – about 15–20 minutes per pool, especially the hottest ones should be shorter (up to 46°).
Cool-down breaks – step out, walk the wooden paths, drink some water or dip in the icy waterfall before getting back in.
Total visit – most people spend 2–3 hours at Termas Geométricas, moving between different pools.
Listen to your body – if you feel dizzy, overheated, or lightheaded, get out, sit down, drink water, and cool down.

Switching between hot and cold, resting, and staying hydrated makes the whole day more enjoyable.

How long does it take from Pucón to Termas Geométricas?

The drive from Pucón to Termas Geométricas takes about 1 hour 45 minutes to 2 hours, depending on traffic and road conditions.

You start in Pucón, right next to Lago Villarrica, and head south.
The road winds past Lago Calafquén until you reach the small town of Coñaripe.
From Coñaripe, the paved road ends and you hit the gravel track: dusty, bumpy, and slower.
the last stretch climbs into the forest and finally drops you at the hot springs parking lot, tucked into the base of the Quetrupillán volcano.

It’s a bit of a mission, but the mix of lakes, mountains, and forest makes the drive part of the adventure.

How many pools does Termas Geométricas have?

Termas Geométricas isn’t just one pool, it’s a whole network of hot springs and a ice cold natural water pool.

20 pools in total
Temperatures range from 35° to 46° Celsius (95°–114.8° Fahrenheit)
Pools are spread out along the red wooden walkways, each with a different size, depth, and heat level
Some are steaming hot, others pleasantly warm — you can move around until you find your favorite
If you walk all the way to the top, you’ll even find ice-cold pools fed directly by mountain water (I jumped in once and almost got hypothermia).
Right in the middle of the baths there’s also a freezing waterfall, perfect if you want the full hot–cold contrast.

Switching between boiling pools and icy water is part of the fun, and kind of a shock therapy, just make sure to drink plenty of water and take it slow, especially when stepping out of the hottest pools (up to 46°).

What happens if it rains or snows at the hot springs?

Bad weather doesn’t ruin Termas Geométricas, it actually makes it even more magical.

Rain – soaking in steaming pools while raindrops hit the surface is a pretty unique experience. The wooden walkways can get slippery, so flip-flops are useful.
Snow – yes, they’re open in winter, and it’s unforgettable. Sitting in 40° water while snow falls around you feels surreal (just keep a towel and warm layer close by for when you get out).
Year-round access – Termas Geométricas is open in all seasons, though winter road conditions can make the drive slower and trickier.

So don’t cancel if the forecast looks bad, rain or snow just adds to the atmosphere.

What's the benefit of the water at Termas Geométricas

The pools at Termas Geométricas aren’t just hot, the water comes straight from underground volcanic springs and is packed with minerals. Locals (and science) say soaking here can do a few good things for your body:

Muscle relaxation – the heat soothes sore muscles and joints, perfect after hiking or long drives.
Improved circulation – alternating between hot pools and the icy waterfall gives your blood vessels a workout.
Skin benefits – the mineral-rich water may help cleanse and soften your skin.
Stress relief – being unplugged in the middle of the forest, with the sound of rushing water, is therapy in itself.

While it’s not a medical treatment, most visitors leave feeling lighter, calmer, and more energized.

How can I get to Termas Geométricas without a car?

Getting to Termas Geométricas can feel tricky without your own wheels, but there are a few good options:

Option 1: Hiking from Pucón to the Termas – this is the hardcore route. It’s a long and challenging hike, but if you’re into adventure, the thought of walking through forest and mountains only to end up soaking in volcanic hot springs is pretty amazing. It has great reviews from hikers who’ve done it, and it’s definitely for those who want the journey to be as memorable as the destination. (link).

Option 2: Car lift from Pucón to the Termas (tickets included) – some tour operators offer packages where you get transport plus entrance tickets in one. It’s a stress-free option if you don’t want to drive yourself. Disclaimer: I haven’t taken this option personally, but it looks convenient if you’re short on time. 2 hours drive, 4 hour at the termen (tickets included) and 2 hours drive back (link).

Option 3: Rent a car in Temuco and drive yourself, this is what I did, and honestly, I recommend it if you enjoy road trips. Picking up a rental in Temuco gives you the freedom to explore lakes, small towns like Coñaripe, and stop for views along the way. The drive itself, paved roads, dirt tracks, forest climbs, is part of the adventure (link).

If you don’t feel like dealing with the gravel road, booking through TripAdvisor is the easiest way. They have multiple options and handle the logistics, so you can just sit back, enjoy the ride, and hop straight into the pools.

Would I recommend Termas Geométricas to friends, family and strangers?

1000% yes. If someone asked me for just one hot spring to visit in Chile, this would be it. The mix of steaming pools, icy waterfalls, forest all around, and those bold red walkways makes it unlike anywhere else I’ve ever been.

I’d tell my friends and family to go for the space and the calm, it never felt overcrowded. And to strangers? Same answer. Even if you’re not usually a “hot springs person,” Termas Geométricas is one of those places that surprises you.

For me, it’s the perfect blend of adventure, design, and relaxation. 100% worth the journey to get there.
