🇦🇷 Argentina · Cuyo
Cacheuta is a small, picturesque thermal spot in Mendoza, tucked in at the foot of the Andes on the bank of the Mendoza river, on the road into the high mountains. It is famous for its hot springs of volcanic origin, which come out of the ground hot and have made this corner a classic destination for relaxation and wellbeing, a short distance from the city of Mendoza.
The setting is spectacular: arid, colorful mountains, the churning river and the clear air of the precordillera. Cacheuta combines the pleasure of the hot springs —in complexes with pools at different temperatures, a spa and services— with adventure activities on the river and in the mountains, and with its position on the road to Potrerillos, Uspallata and Aconcagua.
This guide covers Cacheuta with a practical eye: the hot springs and their complexes, the mountain and river setting, the adventure activities, its closeness to Mendoza and its place on the high mountain corridor, plus the useful details on getting there, enjoying the springs, eating, sleeping and getting around this thermal oasis at the foot of the Andes.
Cacheuta has long been known for its hot springs of volcanic origin, used first by Indigenous peoples and later by Mendoza society. At the start of the 20th century a grand and prestigious thermal hotel operated here, linked to the Trans-Andean railway that crossed into Chile; a flash flood destroyed it in 1934 and, decades later, the thermal complex was reborn as a tourist destination. On the bank of the Mendoza river and on the road into the high mountains, its name has Indigenous roots and its fame is tied to thermal bathing and wellness tourism. The full story is on our history page.

Origins, formation and what the sources say.
The chronicles say that in the days of the Inca Empire there were sick people who walked thousands of kilometers from Cuzco to immerse themselves in these waters: Cacheuta owes its existence and its fame to a natural phenomenon, the hot springs of volcanic origin that rise hot from underground at the foot of the Andes, on the bank of the Mendoza river. These mineral-medicinal waters were known and used from ancient times, and the area lay within the territory of the Indigenous peoples of the Mendoza region, as both the place's own name, of Indigenous root, and the long tradition of using its springs make clear.
Cacheuta's position, at the start of the corridor linking the Mendoza oasis with the high mountains and the pass into Chile, also made it a waypoint on the route through the range. The setting of arid, colorful hills and the powerful Mendoza river, which comes down hard from the glaciers and snowfields of the cordillera, made for a landscape as wild as it is beautiful, marked by the presence of water —hot in the thermal springs, turbulent in the river.
It was precisely the combination of hot springs and a strategic location that laid the ground for the place's later development as a thermal destination, tying Cacheuta's history from the outset to wellbeing, health and the use of its natural springs.
Through the 19th and 20th centuries, the use of Cacheuta's hot springs was organized and professionalized, giving rise to thermal complexes, facilities and hotels. The area joined the tradition of thermal bathing, highly prized at the time for the supposed healing and restorative properties of mineral-medicinal waters, drawing visitors in search of rest, health and wellbeing at the foot of the mountains.
The development of the high mountain corridor and of communications —including, in its day, the Trans-Andean railway that connected Mendoza with Chile across the range— made the region more accessible and increased the flow of travelers. Cacheuta thus established itself as a classic Mendoza thermal destination, tied to health and rest tourism, with its hotel and its pools fed by the hot water.
Over time the offering modernized and diversified, adding daytime thermal complexes, a spa, wellness treatments and services for different kinds of visitor. Thermal bathing remained the heart of Cacheuta's identity, in a setting that pairs the pleasure of hot water with the grandeur of the mountain landscape.
Cacheuta's peak as a thermal destination came at the start of the 20th century with the building of an imposing establishment: the Gran Hotel Termas Cacheuta. It was a prestigious hotel, with thermal facilities, baths and services designed for a well-off clientele in search of health and rest. Its development was closely tied to the Trans-Andean Railway, the audacious line that linked Mendoza with Chile across the Andes and that had a station at Cacheuta, making it easy for Argentine and foreign travelers to reach the springs.
Through those decades, Cacheuta was among the most renowned thermal destinations in the country, its hotel acting as the center of a social and wellness scene at the foot of the mountains. The combination of hot water, mountain scenery and a rail connection made the place a symbol of the health tourism of the era.
Everything changed abruptly in 1934, when a violent flash flood on the Mendoza river swept away much of the site and badly damaged the thermal complex and the area's railway infrastructure. The disaster ended that period of splendor: the old Gran Hotel was left in ruins and Cacheuta entered a long decline, during which its waters, nevertheless, never stopped flowing.
Today Cacheuta combines its historic thermal calling with a broader tourist profile, tied to adventure and to the high mountains. The springs remain the great draw —with their pools at different temperatures, the spa and steam baths in natural caves— and are especially prized on cool autumn and winter days, when the contrast between the cold air and the hot water is at its most pleasurable.
To that was added the use of the Mendoza river for adventure activities, above all rafting, which works the river's rapids in imposing mountain surroundings. The area also offers trekking, horseback riding and the chance to drive the high mountain corridor, which from Cacheuta carries on toward Potrerillos, Uspallata, Puente del Inca, Aconcagua and the pass into Chile.
Its closeness to the city of Mendoza and to the wine regions of Luján de Cuyo and Maipú has made Cacheuta a very accessible, versatile escape, where you can combine thermal relaxation, adrenaline on the river, mountain scenery and wine tourism. So this old hot-water spot keeps its tradition of wellbeing at the foot of the Andes alive, fully part of what the heart of Cuyo offers travelers.
The name of the place itself holds a story that goes back long before any hotel or thermal complex. 'Cacheuta' comes from the Huarpe language and is usually translated as 'valley' or 'the place where people gather', a definition that already hints at the role as a meeting point this site played millennia ago. The Huarpe, the Indigenous people who inhabited what is now Mendoza, San Juan and San Luis, knew and frequented these hot springs long before the Spanish arrived.
With the Inca Empire's expansion southward, the region was absorbed into Tahuantinsuyo, and the springs of Cacheuta took on a character beyond the merely curative: it is said that the sick traveled from Cuzco itself, crossing a good part of the continent, to take the steam and the baths of these waters, considered sacred. That ancestral reputation for healing power is, in a way, the direct ancestor of the wellness tourism that draws visitors today.
Local oral tradition also preserves a legend about the origin of the hot water, starring a chief who gives the place its name. The story goes that, before he died, the chief Cacheuta and his men hid a treasure in the belly of the mountain; and that his spirit, in a last act of generosity or of magic, turned that hidden gold into the thermal waters that have risen hot from the earth ever since. Whatever its exact origin, the legend ties the natural landscape to a local epic that guides still tell visitors, and gives the Cacheuta hot springs a mythical dimension alongside the geological one.
