The Atacama is the driest desert on Earth—so arid that NASA runs Mars mission simulations there. Surprisingly, the extreme dryness means you barely sweat. It also offers some of the purest skies on the planet, where I spotted the Inca-recognized "llamas" in the Milky Way. Base yourself in San Pedro de Atacama, an oasis at 2,500 meters, the gateway to epic excursions. Acclimatize slowly; I arrived feeling dizzy and weak, holing up for a full day at the Alto Atacama hotel (altoatacama.com) with rica rica herbal tea for altitude sickness—a welcome excuse for poolside siestas.
In the Atacama's Luna Valley, snow appears as a mirage amid the desert. Hiking Kari Canyon past jagged peaks, I crossed ocher dunes, red plains, and crimson gorges. Under the blazing sun, a white carpet crunched underfoot like mountain frost: vast salt flats! A stunning clash of sensations, landscapes, and colors. Delicate natural formations—salt flowers and lace—adorned the ground. I'll never forget the earth's subtle music: crystallized salt expanding in the heat, echoing like raindrops on metal in the profound silence.
