Why go to Salar de Uyuni and Sur Lípez?
The Salar de Uyuni is the largest salt flat in the world. Perched at 3,660 metres on the Bolivian Altiplano, this white expanse of nearly 10,500 square kilometres is the remnant of a vast prehistoric lake that dried up thousands of years ago. In the dry season, its surface cracks into a chequerboard of perfect hexagons that runs to the horizon, without the slightest relief to catch the eye. It is a mineral landscape, silent and immense, where you quickly lose all sense of scale. Beneath this salt crust also lies one of the largest lithium reserves on the planet, which gives the place a new strategic importance.
The Salar changes face radically with the seasons. From January to March, in the rainy season, a thin film of water covers the salt and turns the desert into a giant mirror in which the sky and clouds are reflected endlessly. You then quite literally walk among the clouds, in an unreal setting whose photographs have travelled the world. The rest of the year, the dry, solid ground can be crossed by 4x4, which opens up access to Isla Incahuasi and its giant cacti, as well as to the most remote stretches.
But reducing the region to the Salar alone would be a mistake. To the south lies Sud Lípez, a high-altitude desert that climbs from 3,600 to nearly 5,000 metres and unfolds some of the most spectacular landscapes in the Andes. Here you find lagoons tinted red and emerald, perfect volcanoes, fields of bubbling geysers and rock formations sculpted by the wind. It is this sequence, from salt mirror to Andean lagoons, that makes the Uyuni circuit one of the great adventures of South America, often continued to the Chilean border and San Pedro de Atacama.

How much does a trip to Salar de Uyuni and Sur Lípez cost?
The budget depends mainly on the length of the circuit and the standard of the agency you choose. Bolivia remains one of the most affordable countries in South America, but the isolation of Sud Lípez and the cost of 4x4 logistics push the bill up compared with other regions. The prices below are per person for a three-day, two-night circuit, excluding transport to reach Uyuni.
| Style | Per day | What it covers |
|---|---|---|
| Budget | BOB 1,000-1,400 (€130-180) | Three-day group circuit with a budget agency, a salt hotel then a basic refuge, meals included. Minimal comfort and sometimes old vehicles, but most of the landscapes are covered. |
| Comfort | BOB 1,900-2,700 (€250-350) | Reputable agency, small group, experienced driver-guide and recent vehicle, better refuges and well-prepared meals. A good balance between price and safety for a demanding circuit. |
| Premium | BOB 4,000 and up (€520 and up) | Private or upmarket circuit, accommodation in the Salar's few charming lodges, private guide and tailor-made itinerary. The most comfortable way to take on the altitude and the cold. |
The currency is the boliviano (BOB). Uyuni has a few ATMs, but they often break down or run out of cash: it is wise to withdraw money in La Paz or another big city before arriving. Circuits are generally paid in cash, in bolivianos or sometimes in dollars, and entry to the Eduardo Avaroa reserve is paid on site in cash. Cards are only accepted in some hotels and agencies in Uyuni.
Is Salar de Uyuni and Sur Lípez safe?
The main risk on the circuit is not crime but altitude sickness, or soroche, which is very common at these heights, often above 4,500 metres. Headaches, nausea, breathlessness and sleep problems are frequent, especially if you arrive straight from low-lying areas without acclimatising. It is strongly recommended to spend a few days at altitude in La Paz, Sucre or Potosí before setting off, to climb gradually, drink plenty of water, eat light and give up alcohol. Coca tea and, on medical advice, certain preventive medicines help limit the symptoms. The intense night-time cold, which can reach minus twenty degrees in Sud Lípez, calls for very warm clothing, a good sleeping bag and strong sun protection, as the radiation is extreme at altitude. Finally, it is best to choose a reliable agency and a vehicle in good condition, as the isolated tracks leave little recourse if something goes wrong.

The mirror of the Salar de Uyuni 3 654 m
This is the image that defines Bolivia in travellers' imaginations. From January to March, when rain covers the salt with a thin sheet of water, the Salar becomes a perfect mirror that merges sky and earth into a single plane. You move through a setting with no reference points, where silhouettes are doubled and the horizon disappears. In the dry season, by contrast, the same place offers a chequerboard of salt hexagons repeating endlessly, ideal for the famous perspective photos that play on the absence of relief. Many tours leave Uyuni early in the morning or stay for sunset, when the light sets the mirror ablaze. It is a place to experience slowly, far from any frenzy.
Isla Incahuasi and its cacti 3 663 m
In the middle of the Salar's whiteness rises a rocky island bristling with giant cacti: Isla Incahuasi. These green columns, some more than ten metres tall and several centuries old, grow on an ancient fossilised coral reef, a reminder of the vanished lake that once covered the whole region. A marked trail climbs to the top of the island and offers a 360-degree view over the ocean of salt around it. The contrast between the green of the cacti, the white of the ground and the blue of the sky is striking. It is a classic stop on the tours, often chosen for lunch. Access is only possible in the dry season, when the salt crust can bear the vehicles.
Laguna Colorada and its flamingos 4 288 m
Further south, in the Eduardo Avaroa reserve, Laguna Colorada is one of the strangest sights in Sud Lípez. Its waters take on a blood-red hue, caused by algae and mineral-rich sediments that react to the sun and wind. Against this scarlet mirror stand hundreds of pink flamingos, including the rare James's flamingo, which come to filter plankton. Islets of dazzling white borax dot the surface and heighten the contrast. Set at more than 4,200 metres above sea level, the lagoon is discovered in biting cold and often violent wind. It is one of the visual high points of the route, best photographed in late morning when the colour is at its most vivid.
Laguna Verde and the Licancabur volcano 4 353 m
At the far southern end of the circuit, near the Chilean border, Laguna Verde spreads its intense emerald-green waters at the foot of the Licancabur volcano. This spectacular colour comes from the high concentration of minerals, notably arsenic and copper, which shows itself when the wind stirs the lagoon around midday. The perfect cone of Licancabur, which rises to nearly 5,900 metres and marks the border with Chile, is reflected in the green mirror in calm weather. Perched at around 4,350 metres, the lagoon is bathed in harsh light and an almost lunar atmosphere. It is often the southernmost point of the trip, just before crossing to San Pedro de Atacama. The scenery has a rare mineral purity.
The Sol de Mañana geysers 4 914 m
At nearly 4,900 metres above sea level, the Sol de Mañana geothermal field offers a raw, primeval spectacle. Sulphur fumaroles burst from the ground with a muffled roar, while pots of grey mud bubble and burst, throwing out steam. It feels like the earliest ages of the Earth, in a landscape without vegetation where only geology has its say. The visit takes place at dawn, when the cold intensifies the steam and the rising sun colours the plumes. Be careful and follow the guides, as the ground is unstable and the water reaches scalding temperatures. Nearby, the Polques hot springs let you warm up in a natural pool facing the mountains.
How many days, and which itinerary?
The circuit takes one to three days depending on the time you have. In one day, you stick to the Salar itself: the train cemetery, the salt hotel, the mirror effect or the chequerboard of hexagons, then back to Uyuni. The most popular formula remains the three-day, two-night circuit, which combines the salt flat with Sud Lípez and its lagoons, and often ends at the Chilean border post for San Pedro de Atacama. Two days are a compromise for those short of time who still want a taste of the lagoons.

1 day (the Salar only)
Leave Uyuni in the morning for the train cemetery, then the village of Colchani and its salt workshops. Next, head into the heart of the Salar: salt hotel, international flags, perspective photos or mirror effect depending on the season, and in the dry season Isla Incahuasi and its cacti. Back in Uyuni at the end of the day, often at sunset over the salt.
3 days (Salar and Sud Lípez)
Day 1: train cemetery, Salar and Isla Incahuasi, night in a salt hotel. Day 2: crossing Sud Lípez via the Siloli desert, the stone tree, a series of high-altitude lagoons and Laguna Colorada, night in a basic refuge. Day 3: up before dawn for the Sol de Mañana geysers, a dip in the Polques hot springs, then Laguna Verde, before returning to Uyuni or crossing the border into Chile.
Getting there and getting around
The starting point is the town of Uyuni, linked to La Paz, Sucre and Potosí by night bus and by a daily flight from La Paz, which is faster and more comfortable. Almost all visitors explore the Salar and Sud Lípez by 4x4 with a driver, the only realistic way to get around these expanses without roads or signposts. The vehicles generally carry six passengers, a driver-guide and supplies for the whole circuit.
The choice of agency is decisive, for both safety and comfort. It is better to favour a reputable operator, an experienced driver and a well-maintained vehicle than the lowest price. The Sud Lípez tracks are gruelling, the distances long and assistance almost non-existent in the event of a breakdown. For those continuing to Chile, most three-day circuits drop travellers at the border, from where a shuttle runs to San Pedro de Atacama.
Where to stay in Salar de Uyuni and Sur Lípez?
The first night of the circuits is often spent in a salt hotel, a building whose walls, tables and sometimes beds are carved from blocks of salt. The experience is unusual and comfortable for the region, even if the standard remains simple. Uyuni itself has hotels and hostels of every level, handy for arriving the day before and recovering before the early-morning departure.
In Sud Lípez, accommodation becomes much more rustic: shared refuges without heating, basic dormitories and minimal facilities, often near Laguna Colorada. Nights there are freezing, as the thermometer can drop well below zero at these altitudes. Bring a warm sleeping bag or layered clothing, as the blankets provided are not always enough. It is the price to pay for sleeping in the heart of such grandiose landscapes.
What to eat in Salar de Uyuni and Sur Lípez?
During the circuits, meals are prepared by the 4x4 crew and eaten as a group, often in refuges or outdoors facing the scenery. The food is simple but filling: quinoa soups, llama or chicken, rice, pasta and vegetables, with coca tea to help cope with the altitude. Breakfast comes before the dawn departures, and picnics punctuate the long days on the tracks.
In Uyuni, before or after the circuit, the town offers a wider choice of restaurants and pizzerias popular with travellers, as well as markets where you can try Andean specialities. You will find Bolivian classics such as salteñas, pastries filled with meat, and Altiplano soups. It is wise to stay well hydrated and avoid alcohol at altitude, which worsens the effects of soroche.
Entry requirements
Visa-free for up to 90 days a year for UK, US, Canadian and Australian passports, and for EU citizens except Cypriots. US citizens have been exempt since December 2025. Make sure your passport is stamped on arrival: a missing stamp means a fine on the way out.
Rules change: check your own government's travel advice before you go.
Frequently asked questions about Salar de Uyuni and Sur Lípez
When is the best time to see the Salar's mirror effect?
The mirror effect occurs in the rainy season, from January to March, when a thin layer of water covers the salt. On the other hand, some areas become inaccessible, including Isla Incahuasi. To cover the whole of the Salar and Sud Lípez in dry conditions, it is better to come from May to October, even if it means giving up the mirror.
How many days should you allow for the circuit?
One day is enough for the Salar alone, but the classic circuit lasts three days and two nights and combines the salt flat with the lagoons of Sud Lípez. It is the most complete formula, often ending at the Chilean border for San Pedro de Atacama.
Is altitude sickness really a problem?
Yes, it must be taken seriously. The circuit runs between 3,600 and nearly 5,000 metres, an altitude where soroche is common. Acclimatising beforehand for a few days in La Paz, Sucre or Potosí, climbing gradually, staying well hydrated and drinking coca tea significantly reduce the risks.
How do you choose an agency in Uyuni?
The lowest price often hides worn-out vehicles and careless drivers. It is better to favour a reputable agency and check the condition of the 4x4, the number of passengers and the guide's experience. On such isolated tracks, reliability matters far more than saving a few euros.
What should you wear for the circuit?
The climate swings from blazing sunshine by day to freezing cold at night, down to minus twenty degrees in Sud Lípez. Wear layers, bring a hat, gloves and a very warm jacket, a sleeping bag for the refuges, plus sunglasses, sunscreen and strong protection against the extreme radiation at altitude.
