San Pedro de Atacama is the base for exploring valleys, salt flats, lagoons, and geysers, but not all tours are at the same altitude. A smart itinerary starts low and climbs gradually, reducing the risk of losing your most beautiful days to altitude sickness.
Quick answer: Book four days: start with Valle de la Luna, save the high-altitude lagoons for day three, and hit the Gêiseres del Tatio once you’re acclimated. How you feel matters more than a rigid schedule.
How to plan your trip
The nearest airport is El Loa, in Calama, about 100 kilometers from San Pedro. Shared transfers handle the ride. In town, many tours include transportation, but entrance fees may be charged separately. Book with registered operators and check schedules, cancellation policies, and maximum altitude.
Suggested itinerary
Day 1: town and Valle de la Luna. Day 2: Salar de Atacama, Chaxa, or hot springs depending on availability. Day 3: Lagunas Altiplânicas and Piedras Rojas. Day 4: Gêiseres del Tatio at sunrise, then rest. Stargazing tours depend on cloud cover and moon phase. Always leave a buffer for weather and delays.
When to go and what to watch out for
Dress in layers: days can be hot, but early mornings can dip below freezing. Drink water, skip alcohol on your first night, and avoid intense exertion right after arriving. April through June usually sees fewer crowds; summer can bring the altiplanic winter rains and closures.
