🇨🇱 Chile · North and desert
Few places on earth feel as much like another planet as San Pedro de Atacama. This little village of dirt streets and adobe houses, with its white church and its plaza shaded by carob and pepper trees, is only the launching point toward one of the most extreme and beautiful landscapes on the planet: the Atacama Desert, the driest there is. Around the oasis spread endless salt flats, snow-capped volcanoes, turquoise lagoons, steaming geysers and dunes that change color at dusk, all under one of the clearest and most star-filled skies in existence.
But San Pedro isn't only spectacular geology: it's also one of the oldest settlements in Chile, the heart of the Atacameño or Lickanantay culture that has lived in these oases for millennia. In its surroundings there are pre-Inca pukarás (fortresses), adobe villages more than two thousand years old such as Tulor, geoglyphs and the traces of caravans that crossed the desert. The village keeps a colonial church of adobe and cactus wood, declared a National Monument, and an unhurried rhythm of life that tempts you to stay longer than planned.
This guide walks you through San Pedro with a practical, warm eye: how to organize the trips to the El Tatio geysers, the Valle de la Luna, the Salar de Atacama and the altiplano lagoons; how to acclimatize to the altitude; where to watch the stars; and how to get around a destination where almost everything is done through an agency. San Pedro rewards the traveler who respects the rhythms of the desert and the altitude: with good planning, it hands you absolutely unforgettable days in northern Chile.
Long before any city existed, the oases of the Salar de Atacama were inhabited by the Atacameño or Lickanantay people, who for more than ten thousand years adapted to life in the driest desert in the world, farming the oases, herding llamas and alpacas and trading via caravans that crossed the cordillera and the altiplano. That culture left extraordinary evidence, such as the village of Tulor (around 800 BC) and the Pukará de Quitor, a 12th-century stone fortress. Toward the 15th century the Tahuantinsuyo (Inca Empire) absorbed the region, which was folded into the Inca Road, or Qhapaq Ñan. After the Spanish conquest, San Pedro de Atacama established itself as a key point on the route between Upper Peru (Potosí) and the Pacific coast; its adobe church, raised in the colonial period and rebuilt in the 17th and 18th centuries, is a witness to those years. The area belonged to Bolivia until the War of the Pacific (1879-1883), after which it passed to Chilean sovereignty. For much of the 20th century it lived on mining (sulfur, borax) and livestock, until, in the final decades of that century, tourism turned the village into the capital of travel in northern Chile. The full story is on our history page.

Origins, formation and what the sources say.
Long before any town or city existed, the oases of the Salar de Atacama were inhabited by the Atacameño people, who call themselves Lickanantay, an expression from their language, Kunza, usually translated as 'the inhabitants of the territory' or 'the people of the place'. Their presence in the area goes back thousands of years: the hunter-gatherers who occupied the desert and the altiplano gave way, over time, to settled communities that learned to live in one of the most extreme environments on the planet, the Atacama Desert, the driest in the world.
The key to their success was making the most of water. In the oases fed by the rivers coming down from the cordillera (such as the San Pedro and the Vilama) and by springs, the Atacameños developed irrigated agriculture with canals and terraces, growing maize, quinoa, squash and other crops, and supplementing it with llama and alpaca herding. These camelids gave not only meat, wool and leather, but were also the engine of trade: enormous llama caravans crossed the desert and the cordillera exchanging goods between the Pacific coast, the altiplano and the valleys, which turned San Pedro into a crossroads of routes thousands of years old.
Extraordinary evidence of that culture survives. The village of Tulor, dated to around 800 BC, with its circular mud enclosures, is one of the oldest known settlements in northern Chile. The Belgian priest Gustavo Le Paige, a missionary and archaeologist who arrived in the mid-20th century, assembled a monumental collection of pieces that made the historical depth of the region intelligible and gave rise to the archaeological museum that bears his name in the village.
Between the Middle Period and the final centuries before the arrival of the Incas, the Atacameño communities reached a remarkable level of organization. Spread across a series of ayllus (communities bound by kinship and land) around the oasis, they built a society that combined irrigated farming, camelid herding and an intense caravan trade connecting them with cultures as distant as Tiwanaku, on the Bolivian altiplano, and with the coast.
One of the most impressive legacies of this period are the pukarás, stone fortresses built at strategic points. The Pukará de Quitor, raised around the 12th century on the slope of a hill beside the San Pedro river, is the most famous: its walls and enclosures climb the incline and command the valley from a privileged defensive position. These constructions reflect both Atacameño architectural ingenuity and the conflicts of the age.
The richness of Atacameño material culture — ceramics, textiles, tablets for inhaling hallucinogens in rituals, metal objects and the astonishing preservation of bodies and offerings thanks to the aridity — has made San Pedro a world-class archaeological site. The caravan trade, which crossed the desert for weeks at a time driving trains of laden llamas, was the circulatory system that kept this desert civilization alive and connected for centuries.
Toward the 15th century, in its expansion southward, the Tahuantinsuyo (Inca Empire) absorbed the Atacameño region into its domains. The Incas folded San Pedro and the neighboring oases into their vast administrative and road network: the Qhapaq Ñan, or Inca Road, crossed the area, linking it with Cusco and with the rest of the empire. Inca influence was thus layered onto the millennia-old local culture, leaving traces in roads, tambos (way stations) and high-altitude ceremonial centers.
The arrival of the Europeans changed this world brutally. In 1536 Diego de Almagro's expedition toward Chile crossed the Atacama Desert on a punishing journey. But the most remembered episode came in 1540, when Pedro de Valdivia's troops, advancing toward central Chile, reached the region. A detachment under Francisco de Aguirre took the Pukará de Quitor in a bloody fight that broke Atacameño resistance. Tradition and the chronicles remember it as an episode of great violence, commemorated today at the site.
With the conquest, the region fell under Spanish rule and was absorbed into the colonial order. San Pedro de Atacama, thanks to its position on the routes linking the rich mining center of Potosí (in Upper Peru) with the Pacific coast, kept its importance as a waypoint for caravans and merchandise, now within the framework of the Viceroyalty of Peru.
During the colonial period, San Pedro de Atacama established itself as a key settlement in the trade of the north. Its position made it an obligatory stop on the route linking the Pacific coast with Potosí, the legendary silver mountain of Upper Peru that supplied the Spanish Empire with precious metal for centuries. Muleteers, mules and caravans laden with goods passed through San Pedro, and the village remained a vital oasis in the middle of the desert.
The most enduring symbol of this era is the Church of San Pedro de Atacama, one of the loveliest and most representative colonial churches in northern Chile, today a National Monument. Built using the adobe technique (mud and straw), it has a plain white façade and a bell tower that have become the classic image of the village. Its roof is a feat of ingenuity: beams of cactus wood (chañar and cardón) and carob lashed with leather strips, without a single nail. Its origins go back to colonial evangelization, with construction and rebuilding across the 17th and 18th centuries.
The Atacameño region was administratively tied to the Viceroyalty of Peru and, after the independence movements of the 19th century, became part of Bolivia. San Pedro and the whole coastline and desert that are Chilean today were then Bolivian territory, a circumstance that would have enormous consequences in the decades that followed, when the wealth of the desert — nitrate and minerals in particular — set off a conflict that redrew the map of the continent.
Until the end of the 19th century, San Pedro de Atacama and the whole desert that today forms northern Chile belonged to Bolivia (the coastal region) and to Peru (further north). The extraordinary wealth of the desert — nitrate, used as fertilizer and in explosives, along with guano and other minerals — drew Chilean capital and workers into Bolivian and Peruvian territory, and became a source of diplomatic and economic friction.
The conflict broke out in 1879 with the War of the Pacific, which pitted Chile against the alliance of Bolivia and Peru. The war, fought largely over control of the desert's riches, ended in Chilean victory. As a result, vast territories changed hands: Bolivia lost its outlet to the sea (the Antofagasta coastline) and the Salar de Atacama region, San Pedro included, passed into Chilean hands. The Treaty of Peace and Friendship of 1904 definitively sealed the new border between Chile and Bolivia.
Incorporation into Chile changed the administration and the life of the region, although the Atacameño way of life, bound to the oases, herding and farming, persisted. The 20th-century economy around San Pedro rested on smaller-scale mining (sulfur in the volcanoes, borax) and livestock, while large-scale copper mining concentrated at Chuquicamata, near Calama. The village remained a relatively remote oasis, until a new phenomenon transformed it completely at the end of the century.
For much of the 20th century, San Pedro de Atacama was a small, quiet village given over to oasis farming, herding and small-scale mining, well outside the main tourist currents. Scientific interest, on the other hand, did arrive early: the archaeological work of Father Gustavo Le Paige from the 1950s onward brought the region's immense heritage to light and drew the attention of researchers from all over the world.
The great change came in the last decades of the 20th century and, above all, from the 1990s, when San Pedro turned into one of the most important tourist destinations in Chile and South America. The pull of its extreme landscapes — the Valle de la Luna, the El Tatio geysers, the Salar de Atacama, the altiplano lagoons — and the growing ease of access from Calama made the village the excursion base par excellence of northern Chile. Agencies sprang up, along with accommodation running from backpacker hostels to luxury lodges, and a tourism infrastructure that now shapes local life.
Another draw was added to that one, this time looking upward: the exceptional quality of the skies over the Atacama Desert, among the clearest and darkest on the planet, made the region a world epicenter of astronomy, with great observatories such as ALMA, and opened the door to astro-tourism, with stargazing tours that are today one of the most sought-after experiences. The challenge for today's San Pedro is balancing this tourism development with the conservation of its fragile desert setting and with respect for Lickanantay culture, whose communities now manage many of the sites travelers visit.
