Arrive before the main tour buses to capture the most dramatic photographic moments and enjoy the natural hot springs before the crowds descend. Remember to dress in layers, as temperatures can swing dramatically from freezing to warm.
Floating in the Salar's Embrace: Laguna Cejar

Visit in the late afternoon for softer light and fewer crowds, allowing you to truly appreciate the stark beauty of the surrounding salt crusts and the distant Andes. Be sure to rinse off thoroughly at the designated showers afterward to remove the clinging salt.
High Altiplano Serenity: Miscanti & Miñiques Lagoons
Ascend to the breathtaking altitude of the Altiplano to discover the twin jewels of Miscanti and Miñiques, two sapphire-blue lagoons cradled by towering volcanoes.

Essential Travel Tips
San Pedro de Atacama sits at 2,400m, but many incredible tours, like El Tatio Geysers, take you up to 4,300m! Take it easy your first day, drink plenty of water (avoid alcohol), and consider coca tea or leaves (available locally) to help with the altitude. Don't push yourself too hard on arrival.
The desert has extreme temperature swings. You'll need shorts and a t-shirt for midday sun, but a warm fleece, hat, and gloves are essential for early morning tours (like El Tatio) and stargazing nights when temperatures can drop below freezing. Think layers you can easily add or shed throughout the day.
Resist the urge to pre-book all your tours online! Once you arrive in San Pedro, you'll find dozens of agencies, and prices can vary significantly for the same excursions. Spend an hour or two walking around, comparing prices, checking reviews (ask your hostel for recommendations), and don't be afraid to negotiate a little, especially if booking multiple tours.
While some larger establishments accept cards, many smaller restaurants, shops, and even some tour agencies in San Pedro de Atacama are cash-only or charge a fee for card payments. ATMs can be unreliable or run out of money, so it's wise to arrive with a good stash of Chilean Pesos for daily expenses and smaller purchases.
This is one of the driest places on Earth! Carry a reusable water bottle and refill it constantly – dehydration is a real risk. Also, the sun is incredibly intense; pack high-SPF sunscreen, a wide-brimmed hat, and good quality sunglasses to protect yourself from the harsh desert rays.
Atacama boasts some of the clearest skies globally for stargazing. To truly appreciate it, book a dedicated astronomical tour with a professional guide and powerful telescopes. Crucially, check the moon phase – avoid full moon nights, as the moonlight will wash out many of the fainter stars and nebulae.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Frequently Asked Questions
When's the absolute best time to visit the Atacama Desert for stargazing and comfortable exploration?
While Atacama is fantastic year-round for its unparalleled clear skies, I'd personally lean towards the shoulder seasons like April-May or September-October. You'll largely avoid the intense summer heat (December-February) and the slightly colder winter nights (June-August), making daytime excursions much more pleasant. Plus, you might just miss some of the peak crowds, giving you a more serene experience.
I've heard about altitude sickness in Atacama. How serious is it, and what's your best advice for dealing with it?
Altitude sickness, or *soroche*, is a genuine concern, especially since San Pedro de Atacama sits at 2,400 meters (8,000 ft) and many excursions climb much higher. My top tip is to take it easy your first day: hydrate constantly with water (seriously, avoid alcohol!), eat light, and don't rush into high-altitude tours like El Tatio Geysers immediately. Coca tea, widely available, can also help alleviate mild symptoms, but listen to your body.
What's the best way to explore the Atacama's main attractions once I'm in San Pedro de Atacama?
For most visitors, joining organized tours from San Pedro is by far the most practical and safest option. The roads to many attractions can be rough and unmarked, and some sites require specific permits or local knowledge. You'll find countless reputable agencies offering everything from Valle de la Luna to high-altitude lagoons, often including transportation and a guide, which is invaluable for navigating the vast desert.
With Atacama being a prime stargazing spot, are there any specific tips for making the most of a night sky tour?
Absolutely! First, book a dedicated astronomical tour with a reputable guide; they'll have powerful telescopes and expert knowledge to enhance your experience. Dress *extremely* warmly, even in summer, as desert nights are frigid. And here's a pro tip: avoid looking at your phone or any bright lights for at least 30 minutes before the tour to allow your eyes to fully adapt to the darkness – it makes a huge difference in what you'll see.
Beyond the popular Moon Valley and El Tatio, is there a lesser-known spot in Atacama you'd recommend?
If you have an extra day and want to escape the main tourist circuit, consider a trip to the Puritama Hot Springs. While not exactly 'hidden,' they're less crowded than some other spots and offer a truly unique experience. These natural thermal pools are nestled in a canyon, providing a serene, warm soak amidst stunning desert scenery – a perfect way to relax and rejuvenate after dusty excursions.
When visiting indigenous communities or villages, what's important to keep in mind regarding local customs?
Many tours pass through or visit small Atacameño villages, and respectful interaction is key. Always ask permission before taking photos of people, especially children, and be mindful of their privacy. If you're buying crafts, haggle gently if at all, and remember that your purchase directly supports their livelihood. A simple 'Hola' and 'Gracias' go a long way in showing respect and appreciation.
