It's perhaps San Pedro's best-kept secret. Or not. It really depends on your interests. The road is long, but well-paved, until you reach the entrance to the most remote part of the Los Flamencos national reservation: Monjes de la Pacana (Pacana Monks). The place is well above 4500 m: Consider it carefully, as it's not uncommon for people to get altitude sickness. After that, it's a visit to some peculiar stone formations, obsidian quarries, more stone towers (called 'Catedrales'), and the huge Tara salt lake. Fauna is abundant, and particular to that environment. The landscape is stunning at all times-it's easy to catch glimpses of Bolivia here and there, as well. Traffic is light, as this destination's not really popular. If that matters to you, then taking this tour is the perfect way of saying 'I was off the beaten track of San Pedro de Atacama'. The schedule's a lot more flexible than in other tours, so harass the driver and guide as much as you like. There are a few optional treks along the way, but they're difficult to attempt.
Los Flamencos National Reserve is a nature reserve located in the commune of San Pedro de Atacama, Antofagasta Region of northern Chile. The reserve covers a total area of 740 square kilometres (290 mi2) in the Central Andean dry puna ecoregion and consists of seven separate sections.

Feel like visiting the Atacama salt pan, a picturesque village, and some Alp-lookalikes in a single day? Plus eating some local food? Then consider this tour, usually advertised as 'Altiplanic Lagoons', the tour varies very little, if at all, between agencies. You'll be visiting the village of Toconao, renowned for its church and bell-tower; Laguna Chaxa, a national reservation which three species of flamingos inhabit year-round, located at the heart of the Atacama salt pan; Miscanti and Miñiques lagoons, located above 4000 m, and home to a variety of local fauna; and Socaire, a tiny hamlet that lives from selling lunch to tourists-it usually includes home-grown potatoes, big beans, carrots, and quinoa, plus a few other things. There are two different tours, one from 07:00 to 14:00 (half-day), with breakfast but no lunch, and another leaving town at 07:00, and returning at 18:00 (full-day), including lunch and the impressing Piedras Rojas.
They're commonly called 'Hot Springs', but that name couldn't be more of a misnomer. The Puritama (means 'hot water' in Kunza) is actually a warm river, that breaks loose from the stone a few meters away from the actual place. Water temperature usually is around 33ºC. It is amazingly clear and pure, and hosts a budding population of rainbow trout (don't worry, they're tiny and harmless). The "hot springs" are property of Hotel Explora, a five-star brand located in all of Chile's hot spots. The facilities are basic, yet elegant and extremely functional. If you can spare the money, you won't regret it; the landscape's stunning, and the water perfect. Ancient agricultural terraces line the canyon-sides, along with massive stone walls, and even some cacti.
This is one amazing location in summer! Set in the northern tip of the Atacama salt pan, this location offers a splendid panorama of the Andes, and the possibility to bathe in waters as salty as those of the Dead Sea, meaning you can float in the without drowning, even if you cannot swim. The landscape's also remarkable. It usually ends with sunset, along a simple cocktail with pisco sour. The tour sets off at variable times (since Chile follows daylight saving time), but always in the afternoon between 15:00 and 16:00. Besides the Cejar and Piedra lagoons, excursions usually stop by the 'Ojos del Salar' (Eyes of the Salt Pan), two freshwater eyes very close together, and lake Tebenquinche, a water mirror that offers the absolute best sunsets in the whole area-imagine the mountains slowly changing colors, from yellow to pink, and that same image reflected on the lake's perfect surface!
Mars Valley
Like most deserts, Atacama has its share of dunes and sand-banks. The most popular is located here. All sandboarding tours will take you there. The dune is almost 100 m in height; still, the typical track is barely a fraction of that. Some of them offer also to watch sunset in the Moon Valley-but be aware that you won't visit any of its spots, except the Great Dune or the Cari Viewpoint.
Commonly advertised as 'Moon Valley' in English, this part of the Salt Mountain Range offers stunning clinal and anticlinal formations in a perfectly barren landscape. Almost all tours include watching the sunset there—you shouldn't miss it. The large stone walls resemble those of the Grand Canyon in Arizona, sans river. There are also huge halite (rock salt) strata that produce a knocking sound all day long. This can be unsettling at first, but it's actually harmless. Among its prime attractions are the Grand Crater, the Salt Canyon, the Three Maries and salt mines, the Salt Caves, the Cari Viewpoint (also called 'Piedra del Coyote'), and Valle de Marte (Mars Valley). All tours visit a number of these, but it's virtually impossible to know which beforehand. Summer tours tend to be longer, though, and therefore have a greater probability of including more destinations.
Rainbow Valley
It features three different parts, all of them interesting
