The Atacama Desert is an area of extraordinary beauty and astounding natural wonders, from the Atacama Salt Flats, which are home to colonies of nesting pink flamingos and the sacred Incan sites, to the many volcanoes, including the Licancabur Volcano which was a ceremonial center during the Incan period.

The Atacama Crossing takes place in the Atacama Desert in northern Chile – the host town is the wonderful oasis of San Pedro de Atacama. Ranging from dry arid desert, magnificent salt flats stretching as far as the eye can see, sand dunes which will literally take your breath away, to the glittering night skies that only a desert can provide. Explore one of the four astounding deserts in the world.


The archeological jewel of Chile’s rainless plateau, the Atacama Desert, spreads through Chile, Bolivia and Peru. The Atacama Crossing takes place in northern Chile - the host town is the laid back pre-Inca town of San Pedro de Atacama.The small oasis is located in the region of Antofagasta and 100 kilometers / 60 miles southeast of Calama and the Chuquicamata copper mine, overlooking the Licancabur Volcano.

At 2,400 meters / 7.875 feet, and with a permanent population of only 5,000 people, the fantastic atmosphere of the town lends itself to amazing food, comfortable hotels, hostels and an all-around great vibe.

The course of the Atacama Crossing itself is surrounded by forty-four snow-capped volcanoes, with the Lincancabur Volcano always in some range of proximity. The amazing course takes competitors through the magnificent Slot Canyons, which have been referred to some as being in a world with Alice In Wonderland, and The Valley of the Moon, with its lunar resemblance feels as though you are traversing an out of this world terrain. Not only will competitors feel as though they have stepped off planet earth, they will have the opportunity to travel across the special ALMA land, which houses one of the largest telescopes in the world – it is a specially protected area for which 4 Deserts has exclusive access once a year for the Atacama Crossing.


The Atacama Desert is the driest non-polar desert in the world. It is also one of the driest places on earth! However, as this is a desert in proximity to the Andes Mountain range, there can be a chance of some extreme weather including strong winds, rain in the mountains and variations in temperature (as low as -1°C / 30°F at night and even higher than 35°C / 95°F during the day).

September and October are considered to be the months which have the best weather in the Atacama Desert area around San Pedro. It is generally warm and mild, with temperatures reaching 25°C / 77°F during the day. At night it reaches close to 0°C / 32°F.

In recent years, NASA has been testing its Mars Rover and other instruments and vehicles for Mars missions in the Atacama's dry and rugged landscapes. The desert has also been used as a location for filming Mars scenes, most notably in the television series Space Odyssey: Voyage to the Planets. The dry air and low levels of artificial light create perfect conditions for seeing the stars and the area is home to one of the largest telescopes in the world.

This desiccated environment is the perfect preserver of ancient relics, with the world's oldest mummies (of the Paleolithic Chinchorro tribe), having been discovered in the Atacama, thought to date back to 7000BC. Huge geoglyphic paintings adorn hillsides and ruins of Indian fortresses and sacred Inca sites dot the landscape.


Research shows that people began to settle in the Atacama Desert away from the coastal areas around 1500BC. The Atacameno, who were noted for their fortified towns known as pucaras, were originally hunters in search of water, but soon began to domesticate llamas, and grow maize eventually settling the oases of Calama and San Pedro de Atacama between 100BC and 400AD.

By 1000AD, the area came under the control of the Tiwanaku of Bolivia, and then in 1450 the Inca Empire swept in briefly before the desert came under the power of the Spanish.

Today, the desert's population is approximately one million, with most people living in the coastal cities such as Iquique, but some are in the small oasis communities and mining camps. The Altiplano is still the home to descendants of the region's pre-Columbian natives, the Aymara and Atacama Indians, who live the age-old lifestyles of herding llamas and alpacas and growing crops. Along the course, some of the local wildlife might make an appearance, including wild donkeys, vicunas, llamas and alpaca – we challenge to spot the difference (excluding the donkeys!).

The course of the Atacama Crossing allows competitors to experience some of the rich culture in the area by taking them along the Old Inca Road and through the Slot Canyons where they will see rock art from Pre-Incan times.Truly an amazing experience to witness such history in its natural element.


The course of the Atacama Crossing takes competitors across a wide variety of terrain and includes approximately 1,683 meters (5,521 feet) of ascents and 2,508 meters (8,228 feet) of descents over the 7-day race. Starting at just below 3,200 meters (10,500 feet) in the Arcoiris Valley, the race gradually descends over the six stages to finish in the quaint town of San Pedro de Atacama at an elevation of 2,400 meters (7,900 feet).

Competitors will go through magnificent salt flats stretching as far as the eye can see, run down huge sand dunes which will literally take your breath away, go through canyons where you can touch the walls on both sides and sleep under glittering night skies in the driest place on earth.

The course is varied. You will tackle sand-dunes, river crossings, gravel, loose rocks, hard packed earth and even waist high grass. This is in addition to the infamous salt flats (described as "frozen brocoli / a ploughed field") that will challenge even the most dexterous of runners to cross at full-speed.

Each Stage of the Atacama Crossing has unique cultural, historical and scenic highlights that will encourage competitors to push themselves along to the next checkpoint. Below are some of the highlights competitors can expect to experience while crossing the Atacama Desert.

  • Stage 1 – Navigation by Rock will take competitors through the multicolored Valle Arcoiris (Rainbow Valley) and along the Ancient Inca Road where there will be the opportunity to see ancient rock art from the Inca and Aymara traders who used this route in ancient times.
  • Stage 2 – The Slot Canyons ensures that no feet are left dry, but takes competitors along the most stunning canyons of the course. Several breath-taking sand dunes allow for magnificent views across the plains with a chance to descend into the famous Valle de la Muerte (Valley of Death).
  • Stage 3 – The Atacamenos Trail introduces competitors to the “Lonely Tree” before entering the restricted ALMA Project land. The ALMA Project is the most expensive ground-based telescope in operation in the world. Atacama Crossing competitors receive special permission to enter this restricted area each year.
  • Stage 4 – The Infamous Salt Flats are both challenging and surreal.
  • Stage 5 – The Long March will take competitors along the beautiful shores of a lake and across “Cordillera de la Sal” by “Paso Domingo Rames”, climbing and descending challenging dunes, leading into the other worldly place called “La Valle de la Luna (Valley of the Moon).”
  • Stage 6 – The Final footsteps into San Pedro will lead competitors through the last kilometers with a fantastic finish in the ancient adobe-style Town of San Pedro de Atacama.



The total distance of the Atacama Crossing (Chile) 2016 is 250 kilometers / 155 miles. The format is similar to the prestigious 4 Deserts Race Series. Competitors should prepare for the following distances:

  Kilometers Miles Elevation Gain

Total 250 155.3 1,683 / 5,521 2,508 / 8,228

*NOTE: that all distances are subject to change.



During each stage checkpoints are located approximately every 10 kilometers (6 miles) along the course.

At each checkpoint competitors must:

  • Be logged on arrival by the race staff.
  • Take a minimum allocation of drinking water with them for the next leg.
  • Abide by any instructions given by the race staff due to sudden adverse conditions (e.g. thunderstorms, sandstorms, fog, etc).

At each checkpoint competitors can:

  • Rest for a short time and take advantage of the shade the checkpoint tent affords.
  • Seek advice and treatment if appropriate from the medical doctor at the checkpoint.

Please note that adverse weather and other factors can result in changes being made to the course.


The much-anticipated Stage 5 in all of the 4 Deserts events is known as The Long March. Generally, this stage is between 70 and 90 kilometers (43 to 56 miles) long, roughly double the length of the previous four stages.

The stage follows much the same format as the previous ones: checkpoints are located about 10 kilometers (6 miles) apart; however, many competitors will take the opportunity (the only one in the week) to have a few hours sleep at a designated Overnight Checkpoint.

At the Overnight Checkpoint, there will usually be a tent in which competitors can sleep as well as a campfire or stove where hot water is available for drinks and meals.


The Atacama Crossing (Chile) is part of the 4 Deserts Race Series, named by TIME magazine as one of the Top 10 Endurance Competitions in the world.

The Atacama Crossing (Chile) 2019 starts on 29 September and is the fifteenth edition of the race.

The Atacama Desert is recognized as the driest place on earth - it is 50 times more arid than California's Death Valley.

The Atacama Desert has the most lunar-like landscape on Earth and is frequently used by NASA to test its planetary rover vehicles.

The Atacama Desert is 15 million years old. Some of the oldest mummies found on earth come from the Atacama Desert, dating as far back as 7000 years.

The entire Atacama Crossing is held at least 2.3 kilometers / 1.4 miles above sea level and covers the distance required to make a horizontal crossing of the country of Chile (250 kilometers / 155 miles).

The highest elevation on the course is at Camp 1, which is more than 3,000 meters / 10,000 feet above sea level.

Daytime temperatures in October average 35°C / 95°F, while nighttime temperatures average 5°C / 41°F. Temperatures, however, range widely and the desert climate can be extremely hot during the day and cold at night.

Up to 200 competitors representing more than 40 countries are expected to compete in the Atacama Crossing 2019.

Approximately 30% of competitors are expected to have completed a previous 4 Deserts Race / RacingThePlanet Ultramarathon.

The fastest finish time on any Atacama Crossing course is held by Vicente Garcia Beneito of Spain with an overall time of 23 hours and 46 minutes in 2012.

The fastest women's finish on any Atacama Crossing course is held by Anne-Marie Flammersfeld of Germany with an overall time of 29 hours and 49 minutes in 2012.

Approximately 20% of competitors run the entire course, 60% combine running with walking, and 20% walk the entire course. The fastest completion time is expected to be around 25 hours and the slowest around 70 hours.

The Atacama Crossing is a self-supported race; competitors must carry everything they need for seven days on their backs. The average backpack weighs 9kg / 20 pounds. The lightest is generally 7kg / 15 pounds and the heaviest 14kg / 30 pounds.

Many competitors raise money and awareness for charities around the globe through their participation in the Atacama Crossing.

Competitors use tablets in a specially designated Cybertent to write blogs and exchange emails during the race so that friends and family at home can receive some updates and send messages of support.

During the Atacama Crossing, competitors, volunteers and staff will consume approximately 15,000 liters / 4,000 gallons of water during the race.

Competitors are required to pass through up to 30 checkpoints throughout the seven-day event before crossing the finish line.

Bottles: These allow for more flexibility they can be attached to the shoulder straps of your backpack, put in a front pack, kept in the backpack with a Platypus Drink Tube or carried by hand.

Hydration bladders: A popular choice, but sometimes difficult to know how much fluid you have drunk; can also be difficult to fill quickly.

Maintaining your body's electrolyte balance is critical for a safe race. It is strongly recommended to bring a mixture of electrolyte tablets and electrolyte drink powders. You must bring a minimum of:

  • Enough powder to make a minimum of 30 liters of drink OR
  • Enough salt tablets / Endurolytes for 30 hours on the course (usually minimum is 1.5 tablets per hour=45 tablets) OR
  • A combination of both, e.g. powder for 15 liters of water and tablets for 15 hours on the course.
  • If you expect to spend more than 30 hours on the course then you should increase this accordingly. It is vital that you test your electrolyte plan during your training and follow the amounts recommended on the packets.

You are responsible for your own food for the duration of the event. You need a meal for the night before the race as well as a minimum of 2,000 calories / day during the race (7 days) for a minimum of 14,000 calories in total.

Campfire Comfort

The campfire is an integral part of the Atacama Crossing. Nurtured and tended by our local staff, who keep a constant kettle of water boiling, the fire could be counted as the greatest luxury at a 4 Deserts event. After a hard day in the desert, there is nothing quite like the camaraderie and comfort provided by the fire. An opportunity to meet fellow competitors, swap tips, marvel at some of the ingenious meals being prepared and ease sore limbs. Before competitors awake in the morning the fire is rekindled and the kettle boiled for breakfast - a blissful cup of tea or coffee and a bowl of porridge are perennial favourites to savour as the sun rises.

Flags For All Nations

The Atacama Crossing is a truly international event with over 40 nationalities expected to be represented. To welcome each and every competitor, we make sure that we fly the flag of every competitor's nation at the start and finish lines of each stage. Our flags are handmade by a traditional sailmaker, Mr. Poon, who lives and works in Hong Kong. Mr. Poon is a master in his trade, having originally been trained to make sails for junks that used to ply the South China Seas.

Specially Made Tents

The 4 Deserts uses Bedouin style tents specially made in Egypt for the Atacama Crossing. The tradition of tent-making in Egypt is centuries old and the quality of the canvas and design means that the tents are robust in the harshest of conditions and last for years. The tent design includes windows and venting that can capture breezes during the heat of the day but that are also reassuringly draft-proof during cold nights and even sandstorms.

World Class Volunteers

Volunteers are carefully selected from around the world to ensure a variety of nationalities, language abilities, fitness levels and general experiences working in challenging conditions. Approximately four volunteer applications are received for every available position. View our Atacama Crossing volunteer team.

Local Expertise

The 4 Deserts employs a team of local Chilean staff on the ground, many of whom we have worked on the Atacama Crossing since its inaugural event in 2004. These Chileans are an integral part of the Atacama Crossing, facilitating our relationships with government agencies and community leaders. They provide invaluable local expertise and the manpower necessary for keeping the event moving each day and the camps working without hitch each evening.

Local Chilean drivers ensure that media, management and volunteer teams are transported safely around the course. Drivers also help media personnel reach the best vantage points on the course to shoot the race.


Checkpoints are spaced at approximately 10 kilometer intervals, with the final checkpoint of the day being the finish line and campsite. At each checkpoint, competitors are supplied with 1.5 liters of water as well as shade and a place to rest. Once all competitors have passed through the checkpoint, it is dismantled. No trace of the checkpoint is left in the desert.

A Path of Pink Flags
A course team works around the clock to mark all 250-kilometers of the course using mostly small pink flags to make the route as visible as possible. Other course markings include pink ribbon, chalk spray, reflective tape and glowsticks. Competitors must follow these markers from checkpoint to checkpoint.
The Glowing Path
The 4 Deserts uses up to 3,000 glowsticks to mark the Atacama Crossing course at dusk and throughout the dark hours of night. The glowsticks guide the way for competitors during The Long March, offering maximum light while withstanding the heat and other harsh elements of the desert.

The Cybertent is the competitors' lifeline to the outside world. The tent is a unique concept in multi-day stage races as a place for competitors to read emails and blog comments that have been sent to them over the preceding 24 hours. Competitors have the option to send emails and update blogs from the Cybertent at each campsite at the end of the day's stage. The blogs endure as a permanent archive of their experiences in the desert and are accessible through the race website.


There is a fast growing global community interested in 4 Deserts races - not only friends, family, supporters and former competitors, but also a fanbase of people inspired by the dream of one day competing. To keep up with the demands of this expanding community, we are constantly developing our media capabilities.

The 4 Deserts uses a combination of satellite and mobile communications to distribute content from the races to our website and to broadcasters around the world. During each stage of the race we post hourly updates to the website about race leaders and individual competitors. We also post daily video highlights captured by staff, and volunteers.

At least 150 photographs are uploaded daily from the race capturing the locations, highlights and spirit of the event. We also distribute daily features about competitors and the locations as well as stage updates on the race website. Overall positions and timings are logged on the website as soon as possible after the last competitor crosses the finish line of each stage.

Leave No Trace

Catering to the needs of 200 people in the Atacama Desert and making sure that we leave no trace of their presence is an important part of putting on the Atacama Crossing. Fortunately, our competitors are overwhelmingly attentive to this matter and make this task as easy for us as possible. We institute a system of time penalties for any competitor seen littering. Sweepers also follow behind the final competitors removing course markers and remaining litter from the ground.

Finisher Medals

Only those who successfully complete each stage of Atacama Crossing will receive a medal at the finish line in the central square of San Pedro de Atacama. The 4 Deserts specially designs the medals and has them manufactured in Malaysia which is renowned as having the world's best pewter.
