A full-day trip onto the high plain east of the Salar de Atacama is one of the most scenic outings from San Pedro, and often the one that surprises people most. The Altiplanic Lagoons, including Miscanti and Miñiques, are deep blue lakes at around 4,000 m beneath a pair of volcanoes of the same names, and flamingos, Andean gulls and other birds feed in the shallows while vicuñas graze on the surrounding grassland. The colour of the water, a saturated blue against yellow grass and white salt, looks almost painted, and the wind and quiet make the stop feel remote and unspoilt. The lagoons are part of a protected area, so visits are controlled and guided. Piedras Rojas, or Red Stones, lies further along the same route and is the other highlight. Here a field of rust-red volcanic rock sits beside a pale salt lake, with a green-grey lagoon and a ring of cones behind, and the combination of red, white, blue and green is unlike anywhere else in the region. The ground is fragile, so visitors stay on a marked path and walkways, and guides explain the geology, the wildlife and the delicate high-altitude ecosystem. Many tours also stop at the Salar de Atacama and the Toconao area on the way back, giving a sweep from the high plain down to the oasis villages.
How it works
This is a long day, usually twelve hours or so, by minibus along good paved roads and then dirt tracks. You are collected from your hotel early in the morning and returned in the evening. Tours vary in how they combine stops, so check whether yours includes Piedras Rojas, the lagoons, the Chaxa flamingo stop, lunch and entrance fees. Some include a picnic or restaurant meal, and others leave lunch to you.
What to expect
The altitude is similar to El Tatio, and the weather is cold and windy even on sunny days. Dress in layers, with a warm jacket, hat and sun protection, since the sun at this height is strong. Walking is easy but the thin air makes even gentle strolls tiring, so take your time.
Wildlife is the reward for patience
Vicuñas are common along the road, and flamingos can be seen at several of the lakes when conditions suit them. Bring binoculars if you have them, and a camera with a zoom lens for the birds.
Making the most of it
This day works best a few days into your stay, once you have adjusted to the altitude. Keep your first outings gentler, and drink water steadily. Respect the signs and stay on the paths, since the salt crust and the thin soil are easily damaged and take decades to recover.
If you want a quieter experience, ask about small-group departures, and consider combining the trip with an overnight in a nearby village for a different pace. Always check the weather and road conditions with your operator, because storms in the highlands can close tracks.

Often, at the lagoons or in the salt flat, though sightings depend on the season, water levels and conditions. Vicuñas are very common along the road.
How high is the altiplano?+
Most stops are at about 4,000 m or higher, well above San Pedro de Atacama. Allow a couple of days to adjust before this trip.
Is lunch included?+
It depends on the tour. Some include a picnic or meal and others do not, so check before booking and carry snacks.
