The Best Things to Do in Chile’s Atacama Desert
Discover Chile’s Atacama Desert: surreal landscapes, ancient geysers, salt lakes, unique wildlife, and stargazing adventures.
The Atacama Desert, stretching across northern Chile, is one of the planet’s most mesmerizing destinations. Known as the driest non-polar desert on Earth, it surprises visitors with its surreal beauty, unique ecosystems, and a remarkable range of activities for every type of traveler. Whether you’re a seeker of adventure, a wildlife enthusiast, or simply want to marvel at otherworldly landscapes, the Atacama offers unforgettable experiences. This guide covers the essential highlights and hidden gems you shouldn’t miss.
1. Marvel at the Valle de la Luna (Moon Valley)
Valle de la Luna, or Moon Valley, is perhaps the Atacama Desert’s most iconic landscape. Aptly named for its lunar appearance, the valley features dramatic rock formations, vast sand dunes, and salt-crusted terrain shaped by eons of wind and erosion.
- Best time to visit: Late afternoon for golden light and to witness the valley’s surreal transformation at sunset.
- Main highlights: Walk through natural amphitheaters, climb giant dunes, and gaze at jagged peaks that seem sculpted by another world.
- Photography tip: The changing colors at dusk make this a paradise for photographers both amateur and professional.
2. Float Effortlessly in the Salar de Atacama and Laguna Cejar
Salar de Atacama is Chile’s largest salt flat and a shimmering white expanse punctuated by turquoise lagoons. Laguna Cejar, famous for its high salt concentration, allows visitors to float effortlessly on its surface – a sensation similar to the Dead Sea.
- What to expect: Stunning views of volcanoes, flamingos feeding along the shore, and a chance to relax in uniquely buoyant waters.
- Travel tips: Don’t forget to bring a swimsuit and towel. Rinse-off showers are available at the lagoon, but expect chilly water.
- Alternative: Consider visiting Laguna Tebinquinche for sunset reflections of the Andes.
3. Discover the Hidden Lagoons of Baltinache
The Hidden Lagoons of Baltinache are a chain of seven dazzling, turquoise-colored pools surrounded by brilliant white salt crusts. This spot offers peace and tranquility away from busier sites and is an excellent place to enjoy the bold contrast between bright blue water and arid landscape.
- Important note: Swimming in the lagoons was common, but as of 2024, access is strictly controlled and bathing may be prohibited to preserve fragile ecosystems.
- Photographic opportunities: The intense colors and stillness provide some of the Atacama’s most striking visuals.
- Getting there: Reachable by tour from San Pedro de Atacama.
4. Watch the Sunrise Amid the Geysers of El Tatio
El Tatio Geysers form one of the highest geothermal fields in the world. Located at 4,300 meters (over 14,000 feet) above sea level, they deliver a morning spectacle of over 80 active geysers blasting plumes of steam into the frigid desert air.
- Why visit at dawn? The contrast between cold night air and the geothermal heat creates the most dramatic bursts of steam at sunrise.
- Tips for visitors: Wear multiple layers, as temperatures before sunrise can be well below freezing. Altitude can make physical exertion more challenging, so take it slowly and stay hydrated.
- Additional: Some tours include breakfast by the geysers for a memorable meal surrounded by steam vents.
5. Relax at Puritama Hot Springs
Puritama Hot Springs consist of eight cascading geothermal pools nestled in a rocky canyon. The mineral-rich waters, with varying temperatures, offer the perfect way to unwind after days of exploration.
- Facilities: Locker rooms, changing areas, and footbridges connect the pools. Visitor numbers are regulated to preserve the springs.
- Booking tip: Reserve tickets in advance, as spots often sell out, especially during peak travel seasons.
- What to bring: Swimsuit, water shoes, towel, and sun protection.
6. Explore Rainbow Valley’s Colorful Rock Formations
Rainbow Valley (Valle del Arcoíris) is famed for its vivid hills, striped with layers of red, green, ocher, and blue – a result of ancient mineral deposits. This palette of colors makes Rainbow Valley a photographer’s dream.
- Geology: The spectrum of hues is created by varied mineral and volcanic compositions.
- Hiking: Well-marked trails meander through sculpted canyons, offering close-up views of the colorful formations.
- Travel tip: Rainbow Valley is less trafficked than other sites, so you can often enjoy its quiet splendor in relative solitude.
7. Cycle or Trek Through Martian Landscapes
Adventurers will find abundant opportunities to get active in the Atacama Desert. Cycling through canyons and valleys allows you to experience the landscape at your own pace.
- Mars Valley (Valle de Marte/Valle de la Muerte): Not far from San Pedro de Atacama, Mars Valley offers a red-orange terrain of craggy rocks and sandy dunes. Rent a bike and explore winding trails – just be prepared for some strenuous sections due to altitude.
- Devil’s Throat (Garganta del Diablo): A dramatic canyon popular with mountain bikers and hikers; the route features tight passes and panoramic viewpoints.
- Tip: Begin early in the morning to beat the desert heat, take plenty of water, and use sun protection.
8. Try Sandboarding on the Giant Dunes
The Atacama’s colossal sand dunes provide an unexpected thrill: sandboarding. Whether you’re a seasoned boarder or a curious beginner, local operators offer tours with equipment and instruction.
- Popular spots: Death Valley (Valle de la Muerte) has some of the best dunes for sandboarding near San Pedro de Atacama.
- What to expect: Fast rides, plenty of sand in your shoes, and spectacular desert views – especially at sunset.
- Note: Equipment rental and transportation are typically included in guided tours.
9. Observe Wildlife at Laguna Chaxa and Flamingo National Reserve
Laguna Chaxa, within the Los Flamencos National Reserve, is a top spot for bird lovers. The salt flats host three of the world’s six flamingo species: Andean, Chilean, and James’s Flamingos, alongside dozens of other birds adapted to this seemingly inhospitable environment.
- Best time to visit: Early morning or late afternoon when the flamingos are most active and the backdrop glows with warm light.
- Facilities: Walkways and observation points for low-impact wildlife watching.
- Photography: Use a zoom lens for close-ups while keeping a respectful distance from the birds.
10. Stargazing: Experience the Clearest Night Skies on Earth
The Atacama’s high altitude, minimal humidity, and almost zero light pollution make it one of Earth’s premier stargazing destinations. Astronomers from around the globe flock to this region for its superior visibility.
- Astronomical tours: Join a night-time guided tour to peer through observatory-grade telescopes and learn about the southern hemisphere’s constellations, planets, and the Milky Way.
- Top observatories: While some professional installations like ALMA are off-limits to casual visitors, smaller observatories organize educational stargazing sessions accessible to the public.
- When to go: Clear nights are almost guaranteed, but avoid full moon times for the best views of galaxy clusters and nebulae.
11. Visit Unique Museums and Local Markets
For a break from the wild landscapes, explore the region’s cultural and scientific heritage.
- Meteorite Museum: Exhibits feature fragments collected from the Atacama region and interactive panels explaining the science of meteors.
- Archaeological Museum of San Pedro: Displays artifacts from the Atacama’s ancient peoples, including mummies and petroglyphs.
