How many days in San Pedro de Atacama? 4 days, climbing slowly from 2,400 to 4,300 metres
By Tony Panopoulos · travel-agency planner in Greece · Updated
San Pedro de Atacama is an oasis village of adobe houses at about 2,400 metres in the Atacama Desert of northern Chile, among the driest places on Earth. Around it lie salt flats, red valleys, high-altitude lagoons and geysers, and some of the clearest night skies in the world. Give it four days, and plan them by altitude: stay low around the village on the first day, then go higher each day, ending at the El Tatio geysers at about 4,300 metres. Most sights are reached by half-day or full-day tours, and the best light is at sunrise and sunset, when the desert turns red and violet.
Short answer
Three days covers Valle de la Luna, Laguna Cejar, the altiplanic lagoons and El Tatio, but with little time to acclimatise. Four days lets you climb gradually and add stargazing and a bike ride.
The 4-day plan, day by day
Day 1: The village, Pukará de Quitor and Valle de la Luna
Morning. Take it easy on arrival: walk the dirt streets of the village, see the white adobe Iglesia de San Pedro, a colonial church with a ceiling of cactus wood, and the main square under pepper trees. Drink plenty of water and avoid alcohol on the first night.
Afternoon. Rent a bicycle (about CLP$10,000-15,000 a day) and ride 3 km north to the Pukará de Quitor, a stone fortress of the Atacameño people built around the 12th century on a hillside above the river (small entry fee). Climb the path to the viewpoint over the oasis and the volcano Licancabur.
Evening. Visit Valle de la Luna (Moon Valley) for sunset, by tour (about CLP$20,000-35,000) or by bike with an online entry ticket (roughly CLP$10,000-15,000; sold by time slot). See the salt caves, the Great Dune and the salt-crusted ridges as they change colour. Dinner on Caracoles, the main street.
Book the Valle de la Luna sunset slot ahead in high season, and carry a headlamp if you cycle back after dark; the road has no lights.
Day 2: Death Valley, Laguna Cejar and the stars
Morning. Cycle or drive 3-4 km to Valle de la Muerte (also called Valle de Marte), a valley of red rock and steep dunes where you can try sandboarding with a guide (about CLP$25,000-35,000). Then visit the Aldea de Tulor, the excavated remains of an ancient village of round mud houses thought to be more than 2,000 years old.
Afternoon. Join an afternoon tour (about CLP$35,000-50,000 plus fees) to Laguna Cejar, where the water is so salty that you float, Ojos del Salar, two round freshwater pools in the desert, and Laguna Tebinquinche for sunset over the salt flat with a pisco sour.
Evening. Take a stargazing tour with telescopes (about CLP$30,000-45,000), which drive a few kilometres out of the village. The Atacama's high, dry air gives views of the Milky Way, Saturn's rings and, in the southern sky, the Magellanic Clouds.
Stargazing tours are cancelled around the full moon and on cloudy nights; check the lunar calendar when you book.
Day 3: Altiplanic lagoons, flamingos and Piedras Rojas
Morning. Leave at about 7:00 on a full-day tour (about CLP$50,000-75,000 with breakfast and lunch, plus park fees) to the Salar de Atacama. At Laguna Chaxa, in the Los Flamencos National Reserve, three species of flamingo feed in the shallow water among salt crusts.
Afternoon. Continue through the village of Socaire up to the altiplanic lagoons of Miscanti and Miñiques, at about 4,100 metres, deep blue under snow-capped volcanoes. Many tours also stop at Piedras Rojas, red rocks beside a turquoise salt lagoon, depending on weather and access rules.
Evening. Return to San Pedro in the late afternoon, eat early and sleep early, because tomorrow starts before dawn. A main course of quinoa, llama or grilled meat costs about CLP$12,000-18,000.
Walk slowly at 4,000 metres, drink water often and eat light; ask a doctor before the trip about altitude medicine. Altitude sickness can affect anyone, regardless of fitness.
Day 4: El Tatio geysers at dawn and the Rainbow Valley
Morning. Be picked up at about 4:30-5:00 for El Tatio, a geyser field at about 4,300 metres, around 90 km north (about 1.5-2 hours). Tours cost about CLP$35,000-55,000 plus the entry fee. At sunrise the columns of steam are tallest; it is often -5 to -10°C before the sun warms the field, and some tours stop at a thermal pool for a bath.
Afternoon. On the way back, stop at the small village of Machuca, with its tiny church and grilled llama skewers. After a rest, take a half-day tour to the Valle del Arcoíris (Rainbow Valley), with layers of red, green and white rock, and the Hierbas Buenas petroglyphs, carvings of animals left by ancient caravans.
Evening. End with a farewell dinner in the village. Try a pisco sour made with rica-rica, a local desert herb, and finish with a llama or quinoa dish and a glass of Chilean wine.
Dress in many layers for El Tatio: thermal underwear, a down jacket, hat and gloves; you will strip down to a T-shirt by mid-morning.
Only have 3 days?
With 3 days, combine Valle de la Luna with Laguna Cejar on Day 1, then the altiplanic lagoons and El Tatio. It works, but the climb to 4,300 metres comes quickly; drink plenty of water and rest.
Got extra days?
A 5th day can be used for the free weekend visits to the ALMA observatory (booked online well in advance), a hike up a volcano such as Cerro Toco with a guide, or a 3-day jeep tour across the border to the Uyuni salt flats in Bolivia.
Where to stay in San Pedro de Atacama
| Budget | Area | Why | Typical double/night |
|---|---|---|---|
| Budget | Hostels in the village | Simple rooms and shared kitchens, walk to tour agencies on Caracoles. | CLP$35,000-60,000 |
| Mid-range | Central San Pedro | Adobe guesthouses within walking distance of restaurants and tour pick-ups. | CLP$80,000-140,000 |
| Mid-range | Ayllus around the village | Quieter oasis hamlets, more space and dark skies; you need a bike or taxi. | CLP$90,000-160,000 |
| Comfort | All-inclusive desert lodges | Lodges with guided excursions, meals, pools and spas included. | CLP$400,000-1,000,000 |
Getting around
Fly from Santiago to Calama (about 2 hours), then take a shuttle or bus about 100 km to San Pedro (about 1.5 hours; shuttles about CLP$15,000-25,000). Buses also come from Antofagasta and Arica. The village is walkable; bicycles are good for Pukará de Quitor, Valle de la Muerte and Valle de la Luna. Most other sights need a tour or a rented car; if you drive, fill up in Calama and carry water, because distances are long and some high roads are gravel. Tours include pick-up from your hotel.
What to eat in San Pedro de Atacama
Restaurants on and around Caracoles mix Chilean and Andean food. Order empanadas, cazuela (a meat and vegetable stew), quinoa dishes, llama meat and grilled meat, and sopaipillas (fried pumpkin bread). Desert herbs such as rica-rica appear in pisco sours and ice cream. Many restaurants offer a set lunch menu for about CLP$10,000-15,000; dinner costs CLP$20,000-35,000 with a drink. Prices are higher than elsewhere in Chile because everything is brought in from Calama.
Best time to visit
The desert is dry year-round. September to November and March to May have mild days (around 20-25°C) and cold nights, and fewer crowds. Summer (December to February) is warmest and busiest, but the 'Bolivian winter' can bring storms that close high roads. June to August is coldest, with nights below -10°C at altitude and snow that can close El Tatio or the lagoons, but it is the clearest season for stars.
What a day costs

Before you go
Common questions
How do I avoid altitude sickness in San Pedro?
Climb gradually: spend the first day around the village at 2,400 metres, then visit places at 3,000-4,000 metres before El Tatio at 4,300. Drink plenty of water, eat light, avoid alcohol on the first night and sleep well. Symptoms such as headache, nausea or dizziness should be taken seriously; descend and see a doctor if they get worse.
Do I need a tour, or can I drive myself?
You can drive yourself with a rented car, ideally a higher-clearance vehicle, and many roads are paved. Tours are easier for El Tatio, which starts in darkness on gravel roads, and for stargazing with telescopes. Some sites require tickets bought online or at entrances run by local Indigenous communities, and access rules can change.
Can I go from San Pedro to the Uyuni salt flats?
Yes. Many agencies in San Pedro sell 3-day and 4-day jeep tours to Uyuni in Bolivia, crossing the border at Hito Cajón and passing the Laguna Verde, Laguna Colorada and the Salar de Uyuni. Nights are spent in basic lodges at high altitude. Check the visa rules for your nationality and choose an operator with good safety reviews.
Is San Pedro de Atacama expensive?
It is one of the more expensive places in Chile, because almost everything is transported from Calama and most sights require a tour. Expect to spend more on tours and entry fees than on your bed. Booking several tours with one agency can bring a discount, and cycling to nearby sites saves money.
