Chile: Atacama, Geysers and Starry Skies in 8 Days

The Atacama Desert is the world's driest and, paradoxically, one of the most alive places we've visited. Steaming geysers at dawn, altiplano lagoons with pink flamingos, lunar valleys and the planet's cleanest skies for stargazing. ✨ Here's how we spent 8 days in northern Chile.

San Pedro de Atacama: Base camp

San Pedro de Atacama is an adobe village in the middle of the desert at 2,400 meters altitude. Its dirt streets, mud houses and an oasis with pepper trees create a unique atmosphere between rustic and bohemian.

Caracoles Street is the nerve center: tour agencies, restaurants, craft shops and San Pedro's church, Chile's second oldest (1641), built with cactus wood and llama leather.

Acclimatizing on the first day is crucial: we're at 2,400 m and excursions go up to 4,500 m. Drinking lots of fluids, chewing coca leaves (legal in Chile) and avoiding alcohol for the first 24 hours is key. Altitude sickness (puna) can ruin your trip if ignored.

Local cuisine blends Atacameño tradition with modern influences: churrasco (meat sandwich), pastel de choclo, empanadas de pino and llama meat in various preparations. Adobe, on Caracoles Street, has the town's best fusion cuisine.

Valle de la Luna and Death Valley

Valle de la Luna is exactly what its name promises: a lunar landscape of rock formations, sand dunes and salt ridges that looks like another planet. NASA has used it to test Mars rovers due to its similarity to the Red Planet.

The sunset visit is mandatory. We sat on the Great Dune as the sun descended, painting the formations impossible colors: orange, red, violet, pink. When the sun disappears, temperature drops 15°C in minutes and stars begin appearing before it's fully dark.

Death Valley (originally "Mars Valley") offers trekking among eroded rock formations and sandboarding down 100-meter dunes. The adrenaline of the descent mixed with the landscape's beauty is a perfect combination.

The Three Marys, stone formations eroded by wind for millions of years, look like human figures on the horizon. The Salt Cavern, with pure salt stalactites that sparkle with your flashlight, completes a perfect afternoon.

El Tatio Geysers and altiplano lagoons

El Tatio Geysers are the world's highest geothermal field (4,320 m) and the third largest. The excursion departs at 4:00 AM to arrive at sunrise, when the temperature difference between boiling water and freezing air (-10°C) creates steam columns up to 10 meters high.

Over 80 active geysers bubble, hiss and spit hot water. A natural thermal pool lets you bathe at 38°C while the sun rises over the Andean altiplano. It's an experience that defies the senses: hot water, freezing air, steam, absolute silence and a sky shifting from black to orange.

The Altiplano Lagoons (Miscanti and Miñiques, at 4,200 m) are two impossibly blue lagoons surrounded by perfectly conical volcanoes. Andean flamingos, pink and delicate, feed in shallow waters creating a surreal scene.

Cejar Lagoon is another wonder: a high-salinity lagoon (similar to the Dead Sea) where you float effortlessly. It's surrounded by white salt crust that gleams in the sun. The "Eyes of the Salt Flat," two perfectly circular pools of crystal-clear water, are just meters away.

Astronomy and Salar de Atacama

Atacama has the planet's cleanest skies: zero light pollution, 0% humidity and 300 clear nights per year. It's no coincidence the world's most important observatories are here: ALMA (the world's largest radio telescope) and the future ELT (the largest telescope ever built).

Nighttime astronomy tours are a transformative experience. With professional telescopes we saw Saturn with its rings, Jupiter with its moons, the Orion Nebula, globular clusters and the Milky Way with clarity that left us speechless. The Magellanic Clouds (dwarf galaxies visible to the naked eye) are exclusive to the southern hemisphere.

The Salar de Atacama is the world's third largest salt flat and home to the Los Flamencos National Reserve. Thousands of Chilean, Andean and James's flamingos feed in lithium-rich waters. Chile holds 52% of the world's lithium reserves, and most are here.

Tebinquinche Lagoon offers the salt flat's best sunset reflections: volcanoes are perfectly mirrored in the still water like a mirror, creating an unreal symmetry. It's photographers' favorite spot.

Practical tips and budget

Acclimatization is the most important thing: 90% of problems are avoided by ascending gradually and staying hydrated. Local pharmacies sell soroche pills (for altitude sickness) without prescription.

Excursions are booked at Caracoles Street agencies. Prices are fairly standard across agencies (15,000-35,000 CLP per tour ≈ €15-35). Haggling isn't customary but you can negotiate multi-tour packages.

Budget for 8 days (2 people): Accommodation (hostels and boutique): €400-700. Excursions (6-7 tours): €250-400. Meals: €200-300. Santiago-Calama flight: €100-200/person round trip. International flight to Santiago: €400-600/person. Local transport: €50-80. Total: €1,400-2,280 for two people.

Best time: March-November (austral winter has cleaner skies but colder). December-February is summer and altiplano rainy season ("Bolivian winter") which can cancel excursions. Wear layers: daytime can reach 25°C and nighttime -5°C. SPF 50+ sunscreen mandatory: UV radiation at this altitude is extreme.
