Santiago: Cajon del Maipo Termas Colina Trip

The best part of this day is the setting: seven hot-spring pools cut into the Andes, with the Maipo Canyon rising around you. The water is heated by the nearby volcano, and the pools range from a very hot 130°F to a more comfortable 86°F. I like the hotel pickup and the guide-led stories about local traditions. I also like that this is more than a spa visit, since the drive brings mountain passes, forests, lakes, and the old Tinoco Tunnel.

The main drawback is the van. Several departures have used small vehicles with tight legroom, and taller passengers may find the ride uncomfortable. The day can also begin around 5 a.m., and the hot springs can get crowded. Bring food, warm layers, and a towel if possible, since the included picnic is a snack rather than a full meal.

Key points to know before you go

• Seven pools with different temperatures: Choose between water reaching 130°F and cooler pools around 86°F.
• Tinoco Tunnel is seasonal: You visit it from September through December. In winter, the route goes directly to the hot springs.
• A long but scenic day: Allow about 10 hours, including the drive from Santiago and time at the springs.
• Hotel pickup has limits: Pickup is offered in Santiago Centro, Providencia, and Las Condes, though some addresses require a meeting point.
• Guides can handle Spanish and Portuguese: Max, Gonzalo, Sebastián, and other guides have been praised for being friendly and attentive.
• Pack for changing conditions: You need swimwear for the pools and warm clothing for the high mountain roads.

Why the Maipo Canyon makes this more than a spa trip

Termas Colinas is the main prize, but the road there gives the day its character. From Santiago, the van heads into the Maipo Canyon, a dramatic route through the Andes with steep mountain walls, high passes, forests, and glimpses of lakes and open water.

The scenery changes as you climb. Santiago’s city feel gives way to rougher country, and the road becomes part of the experience. I would not book this trip if you want a quick transfer to a spa. You spend a good part of the day in the van, but that drive is what places the pools in such an impressive setting.

Your guide adds local color along the way. The tour includes stories about the area’s customs and folktales, so you get some sense of how people have lived around the canyon rather than simply passing through it with a camera.

The exact views depend on the weather. Clear conditions can reveal broad mountain scenery, while cloud can hide much of the drama. One departure had such heavy cloud that the views were less impressive than expected. The tour runs in all weather, so you should treat clear skies as a bonus, not a promise.

The early pickup and the long ride

This is an early start. One departure began at 5 a.m., and other start times depend on the date and availability. Your pickup is from the hotel lobby, where you should wait 10 minutes before the scheduled time. Drivers wait no more than five minutes after pickup time, so do not cut it close.

Hotel pickup is limited to accommodations in Santiago Centro, Providencia, and Las Condes. Even inside those districts, the company may assign a meeting point if your address falls outside the normal route. Check this before booking, especially if you are staying in a private apartment or on the edge of one of these areas.

Transportation is by air-conditioned van. That is useful for a long day and can make the return ride more pleasant, but the seating is the clearest weak point. A few taller passengers, including people around six feet, found the legroom poor and the seats narrow when the van was full.

If you are tall, broad-shouldered, or prone to stiffness, ask about the vehicle before paying. You cannot choose your seat from the information provided, and a full van can make the two-hour drive to the springs feel much longer.

A breakfast stop may be included in the flow of the day, but breakfast is not part of the price. Coffee and empanadas have been available at a reasonable cost, though you should carry your own snacks as well. There may not be another good chance to buy a proper meal before the return.

Tinoco Tunnel and the old railway route

From September through December, the itinerary includes the Tinoco Tunnel. This dark, disused passage follows the Camino al Volcán and is a leftover from the area’s railway era.

It is not a polished attraction. That is the point. The tunnel feels stark and unusual, and the shrines at its entrance and exit add a serious tone. Your guide explains the tragic story connected with those shrines and gives the tunnel some human context.

Do not expect a long museum-style stop. This is a roadside sight with a story, best appreciated through the guide’s explanation. It also adds variety to the day. You are not only stopping for photographs of peaks and water, but seeing a remnant of the old route through the mountains.

In winter, you skip the Tinoco Tunnel and go directly to Termas Colinas. This means the winter version gives you more time focused on the hot springs, but less of the historical sightseeing. If the tunnel matters to you, book between September and December and confirm the seasonal plan before you go.

Seven pools at Termas Colinas

The hot springs are the heart of the excursion. Termas Colinas has seven pools, each with a different temperature. The hottest reaches about 130°F, while the coolest is around 86°F. That range lets you try different pools instead of sitting in one bath for the entire visit.

The pools are heated by the nearby volcano, which gives the experience a strong sense of place. You are not in a city spa with tiled walls and a treatment menu. You are soaking in naturally hot water in the Andes, with the surrounding mountains doing much of the work.

Plan on roughly two hours at the springs, based on the usual schedule described for the tour. That is enough time to try several pools, sit quietly, and change afterward, but it is not an open-ended spa day.

Crowding can affect the visit. At busy times, the pools may feel full, and the changing bathrooms can become congested. The practical move is to arrive already wearing your swimsuit. Then you only need to change out of it after soaking, which saves you from standing in the changing-room line twice.

Bring a large towel, drinking water, and a robe or extra warm layer for cool days. The supplied information specifically advises swimwear and a change of clothes, but a robe makes the walk between water and changing area more comfortable. You should also pack sunglasses and weather-ready clothing, since the sun and temperature can change quickly in the mountains.

The tour is not suitable for people with mobility impairments, heart problems, a cold, or altitude sickness. The company also advises against joining if you have altitude concerns. This is a mountain outing with a long road journey, not a low-effort city activity.

What is included in the picnic, and what is not

From September through December, the day includes a picnic-style lunch with wine and juice. That sounds like lunch, but you should picture snacks and drinks rather than a full restaurant meal.

One itinerary included a pleasant picnic near the breakfast stop, and another included a stop at a chocolate house where an ice cream or mocha could be purchased. These stops can make the day more enjoyable, but paid items are extra. Breakfast is also extra.

I would bring sandwiches, fruit, or energy bars. You may have limited time and few places to buy food, and the long drive plus hot springs can leave you hungrier than expected. The included wine is a nice touch for a picnic, but it should not replace lunch if you need a substantial meal.

In winter, the picnic is not included according to the seasonal plan. The route goes straight to the hot springs and then back to Santiago. Pack food for the return ride, since the winter schedule may offer fewer food stops.

The guides make a real difference

The guide is important here because the day involves a long drive and several languages. The official guiding languages are Spanish and Portuguese. Some guides have also helped English-speaking passengers follow the schedule through translation apps or repeated explanations.

Max received particular praise for guiding in three languages and keeping everyone clear about the timing. Gonzalo has been described as kind, experienced, attentive, and a good driver. Sebastián was remembered for creating a friendly group atmosphere, and another guide, Marcel, was especially good at taking photos and videos.

Those details matter. You need to understand when to return to the van, how long you have at each stop, and what the guide is explaining about the tunnel and mountain communities. A guide who keeps the group together without rushing everyone can make a long day feel orderly.

Still, English is not listed as an official tour language. If you do not speak Spanish or Portuguese, bring Google Translate or another translation tool. You may be able to follow the main logistics, but you should not assume every explanation will be given in English.

Is the $66 price good value?

At $66 per person, the trip offers solid value if you want the hot springs but do not want to arrange transport into the Andes yourself. The price includes hotel pickup and drop-off, air-conditioned transport, a guide, and entry to Termas Colinas.

Admission to the springs is the key saving in convenience. You also avoid figuring out the mountain route, and a guide gives you context for the tunnel, canyon, and local stories. For a full 10-hour outing, that package is reasonably priced.

The cost does not cover breakfast, extra food, chocolate-house purchases, or every possible version of lunch. The picnic with wine and juice is included only from September through December, so check the seasonal details when you reserve.

Value depends on your tolerance for the van ride. If you are comfortable with a small vehicle and see the drive as part of the Andes experience, the price works well. If your main goal is a spacious ride and a quiet, luxurious spa visit, this is not the right fit.

Free cancellation up to 24 hours before departure and the option to reserve now and pay later make the booking less risky. The tour still runs in all weather, so flexible plans are useful if mountain conditions matter to you.

Who should book this day trip?

I would recommend it to you if you have one free day in Santiago and want to see the Andes without renting a car. It suits people who enjoy scenery, hot springs, local stories, and a full day away from the city.

It is also a good choice for couples and friends who want a memorable soak in a dramatic setting. The different pool temperatures make the visit more interesting than a single hot bath, and the picnic gives the group a simple social break.

You should think twice if you dislike early starts, long van rides, cramped seating, or changing weather. People with heart problems, colds, altitude sickness, or limited mobility should not book this activity.

For the best chance of clear mountain views, consider the season carefully, but remember that weather cannot be controlled. September through December adds the Tinoco Tunnel and picnic. Winter removes those stops and sends you directly to the springs.

What to pack for the Andes and hot springs

Keep your bag practical. I would bring:

• Passport or ID card
• Swimsuit and a full change of clothes
• Warm layers, even if Santiago feels mild
• Comfortable shoes and weather-appropriate clothing
• Sunglasses
• A large towel and, if possible, a robe
• Drinking water
• Snacks or a packed meal

You may go from warm sunshine to chilly mountain air in the same day. Dry clothes are especially helpful after the springs, when you still have the return drive ahead.

Should you book the Termas Colinas trip?

Book it if you want a convenient, reasonably priced route from Santiago to a volcanic hot-spring setting and you are happy to accept a long day in a small van. The scenery, seven pools, and local stories give the outing more substance than a simple thermal-bath transfer.

Before booking, confirm the pickup point, language, season, and food plan. Wear your swimsuit under your clothes, bring snacks and water, and prepare for cold conditions after soaking. If you can handle those practical limits, Termas Colinas offers one of the more memorable ways to spend a day in the Andes.
