Atacama Desert

San Pedro de Atacama is a small oasis village at an altitude of 2,440 meters, which has established itself as a base camp for exploring the Atacama Desert. The dusty main street Caracoles is lined with tour agencies, restaurants, artesanía shops, and cozy hostels — a charming mix of adventure base and relaxed travel destination.

The village itself is quickly explored: The Iglesia de San Pedro (1745) with its cactus wood roof is one of the oldest churches in Chile, and the Museo Arqueológico Gustavo Le Paige showcases 4,000 years of Atacameño history — including mummies, ceramics, and textiles from pre-Columbian cultures.

The true magic lies outside of San Pedro: Within a 100-kilometer radius, some of the planet's most breathtaking natural landscapes await. Plan at least 3–4 full days for the Atacama.

Altitude Adjustment

San Pedro is at 2,440 m, many excursions lead to 4,000–4,500 m. The altitude is no joke: altitude sickness (headaches, nausea, shortness of breath) can affect anyone. On the first day, only light activities, drink plenty of water (3–4 liters), Mate-de-Coca tea helps. Plan geysers and lagoons at 4,000+ meters only from the second or third day.

San Pedro offers accommodations for every budget — from simple campsites to luxury lodges that rank among the best in the world. Almost all are within a 10-minute walk to Calle Caracoles.

Ideal 4-Day Plan for San Pedro de Atacama

The Atacama tours start at different times of the day — the optimal plan maximizes the day and respects altitude acclimatization:

Day 1 (Arrival Day): Acclimatization

Morning: Arrival, check into hotel, explore San Pedro. Visit Iglesia de San Pedro (free), visit Museo Arqueológico (2,500 CLP).
Afternoon: Valle de la Luna at sunset (15,000–20,000 CLP). The tour starts around 3:30–4:00 PM and offers a gentle introduction to the Atacama landscape.
Evening: Pisco Sour at Adobe, early sleep (Geyser tour the next morning!).

Day 2: Geysers & Hot Springs

4:00 AM: Start of the geyser tour (hotel pick-up). 1.5-hour drive in the dark. Sunrise at the geysers, breakfast, bath in the hot pool. Return around 11:00 AM.
Afternoon: Termas de Puritama (optional, 35,000 CLP) — the perfect complement to the cold morning. Or: Rest by the pool, as the 4 AM alarm takes its toll.
Evening: Stargazing tour (9:00–11:30 PM). Book with SPACE or Atacama Desert Stargazing.

Day 3: Salt Flats & Lagoons

All day: Tour to the Lagunas Altiplánicas, Piedras Rojas, and Salar de Atacama (35,000–50,000 CLP). Start around 7:00 AM, return around 5:00 PM. The landscapes on the Altiplano are the most photogenic of the entire trip. Sunset at Laguna Chaxa (flamingos).
Evening: Farewell dinner at Baltinache or CKuri.

Day 4: Departure or Extra Day

Option A: Valle de la Muerte and sandboarding in the morning, then departure to Calama.
Option B: Laguna Cejar (swimming in the salt lake) in the afternoon.
Option C: Bike tour through the village and surroundings (bikes from 5,000 CLP/day).
Option D: Tour to Salar de Uyuni in Bolivia (3 days, from 150 USD) — for those continuing to Bolivia.

Valle de la Luna — The Lunar Landscape

The Valle de la Luna (Moon Valley) is located just 13 km west of San Pedro and is the most iconic landscape of the Atacama. Millions of years of wind and water erosion have created a surreal lunar landscape of salt formations, sand dunes, rugged canyons, and crystalline salt deposits that actually looks as if you have landed on another planet.

Most visitors come for the sunset — and for good reason: As the sun sinks lower, the landscape transforms into a color spectacle. The rocks change from beige to gold to deep red, orange, and violet, while the snow-capped volcanoes on the horizon are bathed in pink. It is one of the most spectacular sunsets in the world.

Highlights in the Valle de la Luna

• Gran Duna: The large sand dune that can be climbed. From the top, you have the perfect 360° view over the valley — the most popular spot for sunset.
• Anfiteatro: A natural amphitheater of salt formations with acoustics that make voices sound like in a cathedral.
• Cavernas de Sal: Narrow salt caves that you can crawl through. Don't forget a flashlight!
• Las Tres Marías: Three striking rock formations that look like human figures.
• Mine Entrance: An old, abandoned mine entrance reminds us that saltpeter and copper were mined in the Atacama for centuries.

Explore on Your Own vs. Tour

The Valle de la Luna can be experienced in two ways:

• Organized Tour (15,000–20,000 CLP): Guide explains the geology and history, transport included, stop at all highlights. Duration about 4 hours. Advantage: Convenient, informative. Disadvantage: Fixed program, little time at individual stations
• Individually by Bicycle (5,000–8,000 CLP bike rental/day): 13 km from San Pedro, flat to slightly hilly. You are independent and can stay as long as you want — especially at the sunset spot. Disadvantage: Return trip at dusk (bring a light!), no guide

Geysers del Tatio — Steam at 4,320 Meters

The Geysers del Tatio are the highest geyser field in the world and with over 80 active geysers, the third largest after Yellowstone and Kamchatka. They are located at an altitude of 4,320 meters, 89 km north of San Pedro — and the only way to experience them properly is at sunrise.

The tours start at 4:00 AM (yes, really). The drive through the pitch-black desert takes 1.5 hours. Upon arrival, it is freezing cold (−10 to −15°C!) — and then the spectacle begins: As the first rays of sunlight hit the icy air, the geysers shoot their steaming fountains meters high into the air. The steam clouds are bathed in golden sunlight, while the surroundings shine in an unreal contrast of ice, steam, and dazzling light.

The geysers bubble, hiss, and spout in different rhythms — some every few minutes, some continuously. In between are hot pools, where you can actually bathe: a surreal experience to sit in steaming thermal water while the temperature around you is below freezing.

Salar de Atacama — The Great Salt Lake

The Salar de Atacama is Chile's largest salt flat at 3,000 km² and the third largest in the world. Its rough, crystalline surface of salt crusts stretches to the horizon, framed by snow-capped Andean volcanoes — a landscape of eerie beauty.

The highlight lies at the edge of the Salar: The Laguna Chaxa is a shallow salt lake where flamingos are reflected — yes, flamingos in the desert! Three species (Andean Flamingo, James's Flamingo, and Chilean Flamingo) wade through the mineral-rich water here, filtering small crustaceans. Their pink silhouettes against the white salt flat and the volcanoes in the background are among Chile's most iconic photo motifs.

Lagunas Altiplánicas

On the Altiplano at 4,100–4,300 meters lie the Lagunas Miscanti and Miñiques — two deep blue highland lakes surrounded by snow-capped volcanoes. The colors are unreal: deep blue of the water, white of the snow, brown of the desert, and the cyan of the sky. Up here, the air is thin, the silence absolute, and the feeling of seclusion overwhelming.

Laguna Cejar

The "Chilean version of the Dead Sea": The Laguna Cejar is a small salt lake with such a high salt content that you can effortlessly float like in the Dead Sea. The turquoise water amidst the white salt desert offers a surreal bathing experience. Afterwards: Watch the sunset at the nearby Laguna Tebinquinche, where the volcanoes are reflected in the mirror-like water.

Piedras Rojas — The Red Stones of the Altiplano

The Piedras Rojas are among the most photogenic landscapes of the Atacama — and that says a lot in a region full of superlatives. At about 4,170 meters altitude, an unreal scenery unfolds: blood-red volcanic rock fragments frame a turquoise highland lake, with snow-capped volcanoes behind a sky so deep blue it almost appears black. The color contrasts — red, turquoise, white, and blue — seem to come from a painting.

The Piedras Rojas are located in the Salar de Talar and are typically visited as part of the full-day "Lagunas Altiplánicas" tour. The tour ascends to the Altiplano — the high plateau at 4,000–4,500 meters — and offers other spectacular stops besides the Piedras Rojas:

Typical Tour Itinerary

• Salar de Aguas Calientes: A small salt lake with flamingos on the way to the Altiplano
• Piedras Rojas: The star of the tour — the red rocks by the turquoise lake. 30–45 minutes stay
• Salar de Talar: Huge salt flat with volcano panorama
• Lagunas Miscanti and Miñiques: Two deep blue highland lakes surrounded by volcanoes. Absolutely surreal
• Salar de Atacama (Laguna Chaxa): Flamingos at sunset

The Clearest Night Sky in the World

The Atacama Desert has the clearest night sky on Earth — and that's no exaggeration. The combination of extreme dryness (almost no clouds, almost no humidity), altitude (2,400–5,000 m, less atmosphere between you and the stars), minimal light pollution, and stable atmosphere makes the Atacama the best place in the world for astronomical observations.

It's no wonder the largest telescopes of humanity are located here: The ALMA Observatory (66 radio telescopes at 5,050 m, the most expensive ground observatory in the world), the Paranal Observatory of the ESO (European Southern Observatory) with the Very Large Telescope, and the under-construction Extremely Large Telescope, which will be the largest optical telescope in the world with a diameter of 39 meters.

What You Can See

With the naked eye:

• The Milky Way in a breathtaking level of detail — with dark dust clouds, bright star clusters, and the luminous band stretching across the entire sky
• The Magellanic Clouds — two dwarf galaxies visible from the Southern Hemisphere (not from Europe!)
• Star clusters like the Pleiades and Omega Centauri
• Planets — Jupiter, Saturn, Venus, and Mars shine so brightly they cast shadows

With a telescope:

• Saturn's rings and Jupiter's moons in sharp clarity
• Nebulae: Orion Nebula, Eta Carinae Nebula, Tarantula Nebula
• Galaxies: Andromeda Galaxy, Centaurus A

Valle de la Muerte — The Valley of Death

Right next to the more famous Valle de la Luna lies the Valle de la Muerte (Valley of Death, sometimes also called Valle de Marte — Mars Valley). The name is said to come from a translation error: Originally it was called "Valle de Marte" (Mars Valley) because the red rock formations resemble the Martian surface, but a French priest read "Muerte" instead of "Marte" — and the name stuck.

The valley is less visited than the Valle de la Luna and offers a more intense desert experience: Massive red rock cliffs, deep erosion gorges, and huge sand dunes that are ideal for sandboarding — snowboarding on sand. Several agencies in San Pedro rent sandboards (5,000 CLP) or offer guided sandboarding tours (15,000–20,000 CLP).

Highlights

• Large Sand Dune: The main dune is about 100 meters high — the climb is strenuous (30 min in soft sand), but the descent on the sandboard is a rush
• Red Rock Cliffs: The erosion formations in deep red and orange are most photogenic in the afternoon light
• Total Silence: Away from the tourist groups, there is a silence that is almost physically palpable — no wind, no animal, no sound

Termas de Puritama — Hot Springs in the Desert

Amidst a deep desert gorge, 30 km north of San Pedro on the way to the geysers, lie the Termas de Puritama — eight natural thermal spring pools connected by wooden walkways. The water has a constant temperature of 33–35°C and flows through a canyon of red rock, lined with cacti and desert plants.

The experience is surreal: You lie in warm, crystal-clear water, above you the deep blue desert sky, around you red rock walls — and all in absolute silence. The Termas are the perfect contrast after the icy morning hours at the geysers: Many tours make a stop here on the way back.

The pools vary in depth and warmth — the upper ones are hotter and quieter, the lower ones cooler and more accessible. The facility belongs to the luxury hotel Explora but is accessible to everyone.

ALMA — The Eyes of Humanity

The Atacama Large Millimeter/submillimeter Array (ALMA) is the most expensive and powerful ground observatory in the world — a joint project by Europe (ESO), North America (NRAO), and East Asia (NAOJ), which cost over 1.4 billion US dollars. The 66 radio telescope antennas (each 12 or 7 meters in diameter, weighing up to 115 tons) are located on the Chajnantor Plateau at 5,050 meters altitude — one of the highest observatories in the world.

ALMA observes the universe in the millimeter and submillimeter wavelength range — wavelengths between infrared and radio waves. This allows ALMA to see things invisible to optical telescopes: The birth of stars and planets in dense gas and dust clouds, the chemical composition of distant galaxies, and the oldest structures in the universe. In 2019, ALMA was part of the network that took the first photo of a black hole.

Visiting

Every Saturday and Sunday, ALMA offers free tours (advance registration on the ALMA website required, booked out months in advance!). The visit leads to the Operations Support Facility (OSF) at 2,900 m — not to the Chajnantor Plateau itself (5,050 m, too high for unacclimatized visitors). There you can see the control rooms, visit an antenna replica, and learn about current research from astronomers.

Other Observatories

• Paranal Observatory (ESO): The Very Large Telescope (VLT) with four 8.2-m mirrors — one of the most powerful optical telescopes in the world. Free Saturday tours, registration via ESO website. 120 km south of Antofagasta
• Extremely Large Telescope (ELT): Under construction on Cerro Armazones — with a 39-meter mirror diameter, it will be the largest optical telescope in the world. Completion expected in 2028
• SPACE Observatory (San Pedro): Private observatory for tourists with high-quality telescopes. Evening astronomy tours, highly recommended (25,000–35,000 CLP)

Life in the Driest Desert in the World

The Atacama Desert appears lifeless at first glance — and in some places, it actually is: In the hyper-arid core, NASA has taken soil samples and found no living organisms. This part of the Atacama is the best analogy for Mars that our planet has to offer — that's why NASA tests its Mars rovers and life-search devices here.

But the desert also has its lively side:

Flora

• Desierto Florido (Blooming Desert): Every 5–7 years, when El Niño brings enough rain, the Atacama transforms into a sea of flowers: Millions of wildflowers (over 200 species) cover the otherwise barren desert floor in pink, violet, yellow, and white. The last major Desierto Florido was 2022/2023 — a natural spectacle that made headlines worldwide
• Tamarugo: A tree that survives in the salty desert by extending its roots up to 20 meters deep into the ground. The Pampa del Tamarugal near Iquique is one of the few forested places in the desert
• Llareta (Yareta): A bizarre, moss-like plant that grows at altitudes over 3,000 m and looks like a green stone. It grows only 1–2 mm per year — some specimens are over 3,000 years old
• Cacti: The candelabra cactus (Browningia candelaris) towers over the desert landscape at altitudes over 2,500 m

Fauna

• Flamingos: Three species live at the salt lakes of the Atacama — Andean Flamingo, James's Flamingo, and Chilean Flamingo. They filter small crustaceans from the salty water with their beaks
• Vizcacha: A rodent that looks like a hare with a squirrel tail. Lives in rock crevices over 3,000 m and is surprisingly tame
• Vicuña: The wild relative of the alpaca, with the finest and most expensive fur in the world. Herds graze in the highlands over 4,000 m
• Andean Condor: The largest flying bird in the world (wingspan up to 3.2 m) circles over the gorges and valleys
• Chinchilla: The wild ancestors of pet chinchillas live in a few colonies in the Atacama — extremely rare and endangered

Geology

The Atacama is a geological open-air museum: Salt pans, copper deposits (Chile is the world's largest copper producer — 28% of world production!), lithium deposits in the Salar de Atacama (one of the largest lithium reserves in the world, crucial for electric car batteries), and volcanic formations. The oldest rocks in the Atacama are over 400 million years old.
