Hot springs in the Andes sounds unreal. It is, and this day trip pairs Cajón del Maipo canyon scenery with soak time at Termas de Colina.

I like how the day feels structured but not rushed, with a mix of viewpoints, short walks, and breaks. Two standouts: the hot springs session, with pools that run from 25 to 55 degrees Celsius, and the variety of stops like Las Melosas and a chocolate boutique stop.

One thing to consider is the early start and the long day on the road, about 8 to 9 hours. Also, hot spring facilities are basic, so you need to come prepared, and comfort depends a bit on the vehicle.

Key highlights at a glance

• Early pickup for morning light on the Andes: you start around 5:30 to 6:00 AM, which sets the tone for a big day.
• Hot springs with multiple temperature levels: plan on a full 2 hours to try different pools.
• Geology stop at Las Melosas, Cajón del Maipo Geopark: polished rocks and deep Maipo River ravines up to 15 meters.
• Small group feel, up to 18 people: easier conversation, more personal attention from the guide.
• Included wine and cheese picnic: an easy Chile tasting moment, plus snacks.
• Guide tips for safe soaking: one guide warning you will hear, limit soaking to about 30 minutes at a time.

Early pickup and small-group comfort from Santiago

This tour runs as a true day trip, usually 8 to 9 hours, and the timing is built for mornings. Pickup is offered from your hotel or similar place, and departures start in that 5:30 to 6:00 AM window. That early start is part of the value, because it gets you onto the mountains while the day is fresh.

You travel in an air-conditioned vehicle, and the group size is limited to a maximum of 18 travelers. That matters more than you might think. In smaller groups, the ride feels less like cattle herding, and the guide can actually keep track of who needs what.

The tradeoff is a long time away from Santiago, and you will spend more hours sitting than you might expect. One practical point: if you are sensitive to vehicle comfort, keep it in mind before booking. A few people flagged that the van seat comfort for the full day may not feel great.

Plaza de Armas stop: a fast Chile history and geography primer

You begin at Plaza de Armas, with a brief intro to why Cajón del Maipo matters to Chile. This stop is short, about 20 minutes, and there is no admission ticket needed for it.

What I appreciate about starting here is how it frames the day. You are not just going for pretty scenery. You get the quick context to understand why the canyon and the Maipo River region are so central to the country’s story. It also helps you notice the details later, like the shape of the terrain and how the river carved its way through the canyon.

Driving the Cajón del Maipo, breakfast break, and possible wildlife

After you leave the city focus behind, you move into the wider canyon region, where views dominate. The route is part of the experience. You get big-sky scenes, mountain ridgelines, and plenty of photo opportunities along the way.

There is a breakfast stop on the route that lasts about 45 minutes. Breakfast is not included, so you will be buying your own food here. The good news is it keeps the day flexible. If you want coffee, something sweet, or a simple bite before the walk and soaking, you can handle it then.

One more thing you should keep in mind: this is a nature-and-views day, and the region can be active with birds and animals. The tour description explicitly mentions Chilean fauna, so the guide may watch for sightings when conditions allow.

Las Melosas geopark walk: polished rocks and deep Maipo River ravines

Las Melosas is one of those stops that turns “scenery” into something you can explain. You do a light walk, about 1 hour, to see a waterfall in the middle of the mountains.

This area is known for polished rocks that look smooth and soft. And then there is the scale: ravines up to 15 meters where the Maipo River runs. That combination of gentle-looking rock surfaces and dramatic cuts in the terrain is what makes Las Melosas feel unusual, even if you have seen plenty of canyon views before.

A big plus here is the geopark angle. It is designated as a geological interest site within the Cajón del Maipo Geopark. Even without a long lecture, having that label changes how you look at what you are seeing. You start connecting how water, time, and geology shaped the place.

Practical note: wear comfortable walking shoes. It is described as a light walk, but you are in mountain terrain, and the ground can be uneven.

Termas de Colina hot springs: soak time from 25 to 55 C

Now for the main event. You spend about 2 hours at Termas Valle de Colina, with hot springs pools that range from 25 to 55 degrees Celsius. The tour includes the hot springs ticket, so you are not doing the math at the gate.

The water is described as mineral-rich, with a magmatic origin linked to the San Jose Volcano. The tour also mentions healing properties such as relief for rheumatic ailments, help with dermal wounds, and purification of toxins, plus mood and stress improvements. I will translate that into something more practical: expect mineral-rich warm water that feels good after a morning in a car and on uneven paths.

What you should definitely plan for:

• You need a towel. One review tip was to pack a towel specifically for the pools.
• The facilities are basic. There is a place to change, but not much else, so bring what you need before you arrive.
• Take the guide’s pacing advice seriously. One guide warning that stands out: do not bathe in the pools for more than about 30 minutes at a time to avoid side effects.

Also, since there are multiple temperature levels, use that to your advantage. Start with a comfortable warm pool, get your body used to it, then move toward hotter ones if you feel good. The best part of the soaking is not just the heat, it is switching between temps as you rest.

Small stops that keep the day Chilean, not touristy

This tour does not only run on hot springs and views. It includes a few quick stops that make the day feel more lived-in.

There is a stop at Casa Chocolate Tienda Boutique, about 1 hour. You can get an artisanal ice cream, taste a hot chocolate, or just slow down and enjoy the particular architecture of the place. It is the kind of break that feels fun rather than forced.

Then you have the picnic time at Los Nogales Roan Jase, about 1 hour, with photos. The picnic included is basic: cheese, wine, and salty snacks. This is one of the moments where you get a simple taste of Chile without needing to hunt for a restaurant mid-route.

One drawback to keep in mind: the picnic location may not offer the best views for everyone. Some people felt the picnic spot was placed somewhere without a view. If you care deeply about eating with a panorama, you might want to bring that mindset, grab your photos quickly, then enjoy the food and move on.

Guides make or break the experience, and this one is human

Most of the best moments come down to the guide. Discover Santiago’s guides are described as punctual, kind, and proactive, with a good attitude and flexibility when plans meet reality.

In the names you might hear, Gonzalo and Sebastian show up in the feedback, and Mat is mentioned as a guide too. Another name, Javier Rojas, appears in a very positive message thanking someone for service quality and integrity. The consistent thread is that guides do their job, explain things at stops, and keep the group moving.

Language also matters on a day like this. You can have a mixed group, so having multilingual guidance helps. The tour description says guides speak several languages, and the group can include people from different countries.

One pacing detail to know: the commentary style may be calmer than you expect. Some people liked that the ride was quieter, with fewer constant talks. If you want nonstop narration from the moment you board, you may not get that. But you do tend to get explanations tied to each stop, which many people find easier to follow.

Safety matters on long drives too. Several people mentioned feeling safe with the guide and driver, and you are in an air-conditioned vehicle with a structured schedule.

Price and value: what you get for $79, and what you pay for yourself

At $79 per person, this is priced as a full, organized day. What you get included is significant:

• Round trip transportation from your hotel or similar pickup point
• An air-conditioned vehicle
• A tour guide
• Passenger insurance
• The hot springs ticket (included)
• Picnic basics: cheese, wine, and salty snacks

What you pay separately:

• Breakfast
• Lunch

So the real value question is whether you would pay for the transport and hot springs ticket anyway. For most people, you are saving the hassle of renting a car, figuring out mountain timing, and negotiating separate entries. You also get a guide to help connect dots between canyon, geopark, and the hot springs.

If you want lunch, plan for an extra-cost stop. Some people noted there can be an optional restaurant lunch available at additional cost, and that it can be good value, but it is not part of the base price.

The final pricing tip is simple: bring cash or card for food, and budget time for the long day. If you go in with that plan, $79 feels like a straightforward way to see more than you could comfortably do alone.

Weather and the mountain reality

This is weather-dependent. The experience requires good weather, and the operator says that if it is canceled due to poor conditions, you will be offered another date or a full refund.

That matters in the mountains. If skies are clear and visibility is good, the views at Cajón del Maipo and the vibe at the hot springs are much more enjoyable. If conditions are rough, the whole day can shift or get canceled, which is why weather planning is part of the decision.

Who this trip suits best (and who should think twice)

This tour is a strong match if you:

• Want a day out of Santiago that mixes city context, canyon terrain, and hot springs
• Like organized pacing with a small group up to 18 people
• Appreciate guides who are flexible and speak multiple languages
• Want an included wine and cheese picnic without having to plan it

It may be a weaker fit if:

• You hate early mornings. Pickup starts around 5:30 to 6:00 AM.
• You get uncomfortable sitting for long periods, since some feedback flagged vehicle comfort for a full-day ride.
• You need lots of amenities at the hot springs. It is a soak and relax setup with limited facilities, though there is a place to change.

Should you book Cajón del Maipo and Termas de Colina?

I think this is a book-worthy day trip for most visitors to Santiago who want something more interesting than another city tour. The combination of canyon views, a short geology walk at Las Melosas, and a 2-hour hot springs session with multiple temperature levels is exactly the kind of “one day, three moods” outing that makes travel feel efficient.

If you do book, go prepared: towel in your bag, shoes for a light mountain walk, and a food budget for breakfast and lunch. And when you get to the pools, follow the guide’s advice about limiting soak time.

If you are the type who dreams about hot springs with Andes views, this is one of the better ways to experience it from Santiago without a car.
