El Tatio is one of the highest geyser fields in the world, and a dawn visit is one of the most memorable things you can do in northern Chile. The field lies about 80 km from San Pedro de Atacama at roughly 4,200 m above sea level, in a high basin ringed by volcanoes. Dozens of vents, fumaroles and bubbling pools release columns of steam into air that can be well below freezing at first light, and the contrast between the cold and the heat is what produces the famous plumes. As the sun rises over the ridge and the air warms, the steam thins and fades, which is why tours leave the village in the middle of the night, usually around four in the morning, to arrive before sunrise. On site your guide leads a walk among the vents, explaining how groundwater heated by volcanic activity is forced to the surface, and pointing out the colourful mineral crusts that ring the pools. You may see a geyser spouting a metre or two, mud pots that burp and pop, and ice crystals on the grass that melt as the day warms. Many tours include a simple breakfast cooked or served beside the steam, and some stop at a natural thermal pool where you can swim if you are willing to change in the cold. The sense of scale, with steam, mountains and a vast sky, is hard to forget.
How it works
Tours are by minibus, collecting you from your hotel in the dark and returning in the late morning. The road is rough in places and the higher section is unpaved, so a guided tour is the practical way to go. Many itineraries add a stop at the Machuca village, a tiny settlement of stone houses with a small church, where vendors sell llama skewers and local snacks, and the road crosses wetlands where vicuñas and Andean birds can sometimes be seen. Expect a total of seven to eight hours.
What to expect
Dress for real cold. At dawn the temperature at the field can drop well below freezing, so layers, a warm jacket, gloves, a hat and a scarf are essential, and even in summer mornings are bitter. The altitude is higher than any other common excursion from the village, so give yourself a couple of days to adjust before going, drink plenty of water, and avoid heavy meals and alcohol the night before.
Some people feel breathless or get a headache, and the guides are used to helping with this. Stay on marked paths, since the crust around the vents can be thin and the water is scalding.
Making the most of it
Bring a swimsuit and a towel if you want to bathe in the thermal pool, a thermos for a hot drink, and a camera with a charged battery that is kept warm in a pocket. Because this is an early start, plan an easy afternoon, and consider booking Tatio for your second or third day rather than your first, after a gentler outing such as the Valle de la Luna. If you are travelling with young children or have heart or breathing conditions, ask your doctor and the operator about the altitude before you commit.

Good questions
Why do tours leave so early?+
The geysers are most dramatic at sunrise, when the cold air makes the steam condense into tall plumes. Arriving after the sun is up means weaker steam, so tours depart before dawn.
How high is El Tatio?+
The field sits at about 4,200 m above sea level, much higher than San Pedro de Atacama. It is wise to spend a couple of days in the village before you go.
Can I swim at El Tatio?+
Many tours stop at a natural thermal pool where you can bathe. Bring a swimsuit and towel, and be ready to change in cold air.
Is breakfast included?+
Many tours include a simple breakfast at the site, but this varies by operator, so check what your tour offers and bring snacks if you want more.
What should I wear?+
Several warm layers, a hat, gloves, a scarf and sturdy shoes. Temperatures at dawn can be below freezing, even in summer.
