Some places stay with you forever because of their beauty and energy, and trekking through the Geysers del Tatio is one of them.
At over 4,300 meters above sea level, deep in the Chilean Altiplano, sunrise becomes a natural spectacle where steam, ice, and sunlight compete for attention.
When I took this tour—still before dawn—the temperature was below freezing, and the sky felt incredibly close. The cold was intense (dress warmly!), but the moment the first fumaroles appeared made every shiver worth it.
Where are the Geysers del Tatio and why are they so impressive?
The El Tatio Geothermal Field is located about 90 km from San Pedro de Atacama, in Chile’s Antofagasta region. It’s the third-largest geyser field in the world and the biggest in South America.
More than 80 active geysers shoot jets of steam and boiling water up to 10 meters high.
Altitude, climate, and best time to visit
- Altitude: 4,320 meters (14,170 ft)
- Temperature: between –10 °C (14 °F) and 20 °C (68 °F) during the day
- Best time: between 5:30 and 7:30 a.m., when the contrast between cold air and hot vapor creates surreal colors and light
What to expect from the landscape
Reddish mountains, thermal pools, pure air, and a total sense of isolation. As the sun rises, the steam columns glow pink and gold—it truly feels like being on another planet.
How to get from San Pedro de Atacama to the Geysers del Tatio
From San Pedro de Atacama, the trip takes about 1 hour and 30 minutes along a high-altitude road.
Most tours depart between 4:00 and 4:30 a.m., arriving just in time for sunrise.
Practical tips for the early morning
- Dress in layers: thermal clothes, hat, gloves, and scarf are essential.
- Stay hydrated: altitude can hit you unexpectedly.
- Bring sunscreen and water: the sun gets intense after 8 a.m.
Trekking among fumaroles: living the experience
Walking between the steaming vents is both humbling and awe-inspiring. Paths are marked for safety since the water can reach over 85 °C (185 °F).
In my case, the experience was flawless. Our guide Carolina was professional and friendly, always checking on the group. On another visit, Malu, another excellent guide, made the excursion fascinating and cared for every traveler.
First light of the day
As the sun rises, the vapor turns golden and pink. Cameras can’t truly capture what it feels like to stand in the middle of a steaming field surrounded by snowy mountains.
Guided walk and safety
The organization was impeccable—punctual, attentive, and well-coordinated. The trek isn’t hard, but at this altitude, it’s best to walk slowly and let your body adjust.
The high-altitude breakfast that makes a difference
After the walk, we enjoyed a delicious outdoor breakfast with hot coffee and fresh bread. Maybe it was the cold, maybe the view, but it was one of the most memorable breakfasts of my life.
What to pack and how to prepare for the trek
- Thermal layers and windproof jacket
- Hat, gloves, and scarf
- Trekking shoes or non-slip soles
- Water, sunscreen, and sunglasses
- Camera or phone (keep it warm—batteries drain fast in the cold)
At this altitude, it’s smart to arrive in San Pedro at least one day early to acclimatize.
Wildlife, geothermal wonders, and curiosities
El Tatio is a natural geothermal laboratory, where underground water is heated by volcanic magma and rises as steam.
Around the site, you’ll often spot vicuñas, flamingos, and llamas grazing near the wetlands.
If you’re lucky, you’ll see the sunrise reflected in the thermal pools—one of the most beautiful images of northern Chile.
Final tips and personal recommendation
Of all the excursions I did in northern Chile, this was one of the most interesting and beautiful.
The contrast between the freezing air, the silence, and the rising steam creates an almost magical atmosphere.
The group, the guide, and the breakfast made the experience totally worth it.
My advice: don’t miss it—and go warmly dressed! El Tatio isn’t just a place to visit; it’s a place to feel.
