Antofagasta

The Antofagasta Region is where the driest desert on Earth meets some of the clearest skies in the universe. Home to the ALMA radio telescope array and world-class observatories, it is a pilgrimage for astronomers and stargazers alike. San Pedro de Atacama is the adventure hub for volcano treks, flamingo lagoons, and the surreal Moon Valley.

San Pedro de Atacama, Desert Capital of Adventure

Nestled at 2,400 metres in an oasis at the edge of the Salar de Atacama, San Pedro de Atacama has transformed from a dusty adobe village into South America's premier desert adventure destination. Its single-storey mud-brick streets, refreshingly free of high-rises by local building code, are lined with tour agencies, craft-beer bars, and international restaurants, all catering to the steady stream of backpackers, photographers, and astronomers drawn by the region's extreme landscapes.

From here, day trips radiate in every direction: sandboarding down the dunes of Valle de la Muerte, cycling to the ancient pukará fortress of Quitor, floating in the salt-saturated Laguna Cejar, or watching sunset paint the eroded rock formations of the Moon Valley in shades of amber, rose, and violet.

The town is also the staging point for some of the continent's highest volcano ascents.

Geysers, Salt Flats, and High-Altitude Lagoons

At 4,320 metres above sea level, the El Tatio geyser field erupts at dawn with over 80 active geothermal vents sending columns of steam into the freezing morning air, the third-largest geyser field on Earth and the highest. Visitors arrive in darkness to watch the spectacle at sunrise, then warm up in natural hot spring pools while vicuñas graze in the foreground.

South of San Pedro, the Salar de Atacama stretches for over 3,000 square kilometres, its crusty white surface broken by turquoise brine pools where thousands of flamingos feed on tiny brine shrimp. Further south, the Miscanti and Miñiques lagoons sit in volcanic craters at nearly 4,200 metres, their deep blue waters framed by copper-coloured peaks.

The Tara salt flat, accessible only by 4x4, shelters the bizarre rock pinnacles of the Monjes de la Pacana, natural stone columns that resemble hooded monks standing sentinel on the altiplano.

Astronomy Under the Clearest Skies

The Atacama Desert's combination of extreme aridity, high altitude, and minimal light pollution has made the Antofagasta Region the global epicentre of ground-based astronomy. The ALMA (Atacama Large Millimeter Array) observatory, at 5,000 metres on the Chajnantor plateau, is the world's most powerful radio telescope, a collaboration of 66 antennas probing the origins of stars, planets, and galaxies.

Nearby, the European Southern Observatory operates the Paranal complex, home to the Very Large Telescope, whose four 8. 2-metre mirrors have captured images of exoplanets and distant black holes.

For amateur stargazers, San Pedro offers nightly telescope tours where the Milky Way arches overhead with a brilliance that is genuinely life-changing. The region will soon host the Extremely Large Telescope, whose 39-metre mirror will be the largest optical telescope ever built.

Copper, Lithium, and the Mining Frontier

Beneath the desert's barren surface lies extraordinary mineral wealth. Chuquicamata, just outside the city of Calama, was for decades the world's largest open-pit copper mine, a terraced crater over 4 kilometres long and 850 metres deep, now transitioning to underground extraction. The region produces a significant share of the world's copper and is increasingly central to the global lithium supply, with vast brine deposits beneath the Salar de Atacama feeding the batteries of electric vehicles worldwide.

The mining city of Antofagasta, the regional capital, has grown into a modern port hub with upscale restaurants, ocean-front boardwalks, and the iconic La Portada, a natural stone arch rising from the Pacific that has become the city's symbol.

Mining heritage tours take visitors through the abandoned camps and railways that once connected the desert to the coast.

Ancient Cultures and Living Traditions

Long before the mining booms, the Atacama Desert supported complex civilisations. The Atacameño (Lickanantay) people built irrigated villages, terraced hillside farms, and trade networks spanning from the Pacific to the jungle lowlands of present-day Argentina and Bolivia. The R.P. Gustavo Le Paige Archaeological Museum in San Pedro houses one of the finest pre-Columbian collections in Chile, including ceremonial tablets, gold ornaments, and textiles that reveal sophisticated artistic and spiritual traditions.

Today, Atacameño communities in villages like Toconao, Socaire, and Machuca maintain ancestral practices, from irrigation channels that date to pre-Inca times to the harvest festival of Limpia de Canales, where entire communities gather to clean and bless the ancient waterways.

The region's cuisine blends these traditions with desert ingredients: rica-rica herb, chañar fruit syrup, and slow-cooked camelid meats prepared in earth ovens.

Points of interest for this region are coming soon.
