The day has two distinct halves — a border crossing in the morning and a lunar landscape at sunset — with the town of San Pedro serving as the hinge between them. Everything before lunch is about getting through the mountains and into Chile; everything after is about the light on the salt.

To the Border

The morning departs Susques early, fuel at the YPF station before the town's low adobe grid gives way to the open puna one last time. Ruta 52 west is fully paved, a fast, well-maintained road across increasingly stark terrain, climbing steadily toward the frontier.

The Complejo Fronterizo Jama sits at 4,200 metres, one of the highest integrated border posts in the Andes — both Argentine exit and Chilean entry formalities are handled at a single facility here rather than at two separate posts kilometres apart, which makes this one of the more straightforward high-altitude crossings in the region. Passport and vehicle documentation are checked on the Argentine side, followed immediately by Chilean entry processing and the standard SAG agricultural declaration — no fresh fruit, meat, dairy, or honey crossing into Chile undeclared. Beyond the complex, Chilean Route 27 descends steadily off the altiplano, paved the entire way, dropping through increasingly dramatic desert scenery toward the oasis at the bottom.

Lunch — San Pedro de Atacama

By early afternoon the road arrives at San Pedro de Atacama, a low adobe town that has served as an oasis and crossroads in this stretch of the Atacama for centuries, long before it became the tourist gateway it is today. Lunch is at Sol Inti, a modest, unpretentious restaurant popular with both locals and travellers for its honest pricing and generous lunch menu — a good, unhurried meal before an afternoon that will otherwise run until sunset.

Valle de la Luna

A short drive from town, the Valle de la Luna sits within the Cordillera de la Sal, a mountain range shaped over millions of years as an ancient lakebed was slowly uplifted by tectonic movement and then sculpted by wind, sun, and rare rain into a landscape that has drawn comparisons to the lunar surface since at least the mid-20th century. The road through the reserve runs in a single line to a dead end and back, with each stop along the way built up from millions of years of salt, gypsum, and clay.

Duna Mayor, the great dune that gives the first stop its name, offers a wide panoramic view across the whole valley toward the Cordillera de la Sal — the light here shifts constantly through the afternoon, the rock turning from reddish to violet to grey as the sun drops. Further along, Achaches presents two strikingly white mineral outcrops from a mirador on the opposite side of the valley, a different angle on the same folded, salt-streaked terrain. The road continues past the remains of the old Mina Victoria, a 20th-century salt-extraction operation whose disused machinery still sits where it was abandoned, before reaching Las Tres Marías at the end of the line — three upright rock formations shaped by wind, water, and the salt embedded in the stone, said by some to resemble three women in different postures. The formations are fenced off at close range now, following past incidents of damage, but they remain the most photographed single feature of the reserve.

Mirador Coyote — Sunset

From Tres Marías, the route doubles back the way it came, out of the reserve and onto the highway toward Calama, where a short unpaved turnoff leads to the Mirador Coyote (also known as Mirador de Ckari), the highest viewpoint associated with the valley and the traditional spot to watch the sun go down over the Cordillera de la Sal. The perspective from here is wider than anything inside the reserve itself — the full sweep of salt mountains catching the last light, the Licancabur volcano often visible on the horizon beyond. Access to this mirador has been intermittently restricted in recent seasons due to safety concerns over the approach path, so it is worth confirming locally on arrival in San Pedro whether it is currently open; if closed, the view from Duna Mayor at the same hour is a more than adequate substitute.

Arrival: San Pedro de Atacama

The return to town after sunset closes a long day that began in the mountains of Jujuy and ends in the desert oasis that will be home for the next several nights. San Pedro's low, dusty streets and adobe buildings hide a surprising density of restaurants, tour operators, and archaeological history — enough to fill the coming days at altitude far lower than almost anywhere else on this stretch of the trip. Tonight, though, is simply about food, rest, and letting the last of the day's light fade from the sky.
