Advance online tickets are mandatory for major Atacama Desert sites like Valle de la Luna (10,800 CLP) and Puritama Hot Springs (35,000 CLP). Gates open as early as 06:00 at El Tatio Geysers, and rangers rarely accept physical cash at the entrances.
The Atacama Desert operates through individual park gates rather than a central entrance, with major sites opening between 06:00 and 08:30 daily. El Tatio Geysers unlock earliest to catch the morning steam columns, while sunset spots like Valle de la Luna cut off vehicle entry at 16:00. Flash floods during the January to February Altiplanic Winter frequently force sudden road and park closures.

Check CONAF alerts locally before driving to remote gates.

View All ToursMarch to May and September to November provide the most reliable conditions for visiting the Atacama Desert. Traveling during these shoulder seasons guarantees mild temperatures and thinner crowds at major sites like Valle de la Luna. Avoid January and February entirely, as the Altiplanic Winter triggers sudden flash floods that wash out desert roads in minutes.
Plan for 4 to 5 days in the Atacama Desert. The timeline depends heavily on whether you join guided van tours or rent a high-clearance 4x4 to navigate remote tracks yourself. Reaching high-altitude sites like El Tatio at 4,320 meters requires at least 48 hours of acclimatization in San Pedro before attempting the drive.
Schedule your El Tatio Geysers visit for the end of your trip. Visitors need 48 hours to acclimatize to the 2,400-meter baseline before ascending to 4,320 meters. Altitude sickness causes severe headaches and vomiting, requiring immediate medical attention in San Pedro.
Stargazing excursions shut down during the three days before and after a full moon. Bright moonlight washes out the night sky, causing operators to cancel or limit telescope sessions. Check the lunar calendar before locking in your travel dates.
Advance online booking is mandatory for Valle de la Luna, Puritama Hot Springs, and Lagunas Altiplánicas. Main gates rarely accept cash, though you still need physical Chilean Pesos (CLP) for rural artisan shops. Withdraw money before the weekend, as Caracoles Street ATMs frequently empty out.
Pack heavy jackets alongside lightweight daytime clothing. Temperatures plunge by 30°C within an hour of sunset, hitting -15°C at night. You must also apply SPF 50+ sunscreen every 90 minutes during the 30°C days, as UV radiation is 40% stronger here than at sea level.
Skip visiting in January and February. This weather phenomenon pushes Amazon moisture into the extreme aridity, triggering sudden thunderstorms. Flash floods wash out roads in minutes, forcing CONAF to shut down park access without warning.
Valle de la Luna costs 10,800 CLP, Laguna Chaxa is 12,000 CLP, and Puritama Hot Springs charges 35,000 CLP. Advance online booking is mandatory for Valle de la Luna, Puritama, and the Lagunas Altiplánicas. Entrance gates rarely accept cash.

Online reservations are mandatory before arriving at Valle de la Luna, Puritama Hot Springs, and Lagunas Altiplánicas. Free public tours of the ALMA observatory run on weekends but require booking two to three months ahead. Unlicensed street vendors sometimes lack emergency radios or oxygen tanks, so verify your operator is SERNATUR-registered.
March through May and September through November provide mild temperatures and fewer crowds. January and February bring the Altiplanic Winter, pushing moisture from the Amazon into the desert. These sudden storms trigger flash floods that wash out roads in minutes, forcing CONAF to close access routes.
Smaller rural sites and artisan shops do not accept credit cards. Carry physical Chilean Pesos (CLP) for these remote checkpoints. ATMs line Caracoles Street in San Pedro, but they frequently run out of cash during weekends and peak seasons.
Schedule high-elevation excursions, like the 4,320-meter El Tatio Geysers, for the final days of your trip. Spend your first 48 hours acclimatizing in San Pedro de Atacama at 2,400 meters. Failing to adjust can trigger severe altitude sickness, requiring an immediate return to town for medical attention.
Operators cancel stargazing excursions during the three days before and after a full moon. Bright moonlight washes out the constellations, ruining visibility even in a region boasting 300 clear nights a year. Check the lunar calendar before booking flights to ensure you can actually use the high-powered telescopes.
