El Tatio Geysers

The van left San Pedro at 4am. I sat in the dark with six other people, none of us speaking, all of us wearing every layer we’d packed and wishing we’d packed more. The road climbs from 2,400 meters to 4,300 meters in about two hours, switchbacking up through a landscape you can’t see but feel — the air thinning, the temperature dropping, something shifting in the equilibrium of the world. When we stopped and stepped out, the cold hit like a physical object.

Then the geysers. They were already active in the pre-dawn dark, columns of steam rising ten, twelve meters into the air, backlit from below by the faintest geological warmth. The ground around the vents was painted in sulfurous yellows and reds that showed up even in the half-light. You stand two meters from a geyser that is shooting superheated water out of the earth and the noise is a low, sustained roar, like something breathing that is very, very large. I kept stepping closer. The guide kept pulling me back.

The sun crests the ridge line fast when it comes. Within minutes the steam columns turn from grey to white to gold, the colors of the mineral deposits around the vents leap into visibility — rust, canary yellow, bone white — and the mountains that form the backdrop reveal themselves as enormous and snow-capped. What had been mysterious and slightly terrifying in the dark becomes, in the sun, spectacular in a different and more straightforward way. Both versions are true. I preferred the dark.

Breakfast is served at sunrise by the tour operators, often quinoa porridge and hard-boiled eggs and instant coffee in styrofoam cups. At 4,300 meters, instant coffee in a styrofoam cup is the most satisfying drink I have ever had. My hands were shaking slightly — from altitude, from cold, from I’m not sure what else. The person next to me was crying, quietly, looking at the steam rising into the blue. I understood completely. There is something about being this high, this cold, this early, watching the earth exhale, that breaks something open. The guide had seen it hundreds of times. He handed out the coffee without comment.

There is a thermal pool near the main geyser field where you can swim. At 4,300 meters in the morning cold, lowering yourself into hot geothermal water with the steam columns visible fifty meters away is an experience that sits in memory with unusual clarity. The contrast between the freezing air and the warm water is almost painful. Then it isn’t. I floated there for twenty minutes with my face tilted up at the sky, which was turning from pale gold to a blue so saturated it looked digital.

When to go: Any time of year, but the pre-dawn visit is the whole point — the spectacle fades as the temperature rises and the pressure differential drops. The geysers are most dramatic between 6am and 8am. Dress for temperatures well below freezing. Acclimatize in San Pedro for at least two nights before the climb.
