San Pedro de Atacama sleeps at 7,900 ft, which sounds manageable until you read the day-trip itineraries. El Tatio at sunrise is 14,170 ft. The Lagunas Altiplánicas and Salar de Tara are above 13,000 ft. The standard tour pattern is a 4 a.m. departure that climbs 6,000 ft in two hours, before your body has had a single night to acclimatize. CDC flags rapid ascent above 3,400 m as the textbook setup for acute mountain sickness, and recommends a low threshold for acetazolamide prophylaxis. Started the day before you fly to Calama, Diamox cuts both the rate and severity of AMS so the sunrise you booked is one you can actually stand up for.

Atacama Desert medication FAQ
- San Pedro itself is at 7,900 ft, which is right at the lower edge of the threshold where altitude illness becomes a real concern. The reason the medication still matters is the day-trip pattern: El Tatio at 14,170 ft, the Lagunas Altiplánicas above 13,000 ft, the Salar de Tara above 14,000 ft, and most operators leave before sunrise on day one or two. CDC flags rapid ascent above 3,400 m as the setup that pushes AMS rates toward 50% in unacclimatized travelers, and recommends a low threshold for acetazolamide. If your itinerary includes any of the standard high-altitude day trips, the medication is worth having before you land in Calama.
Get the Rx before you fly to Calama.
Start the medication the day before you ascend. Pick it up at your pharmacy before your flight, and you'll be covered through the first nights in San Pedro and the high-altitude day trips that start before sunrise.
