The classic Uyuni 3-day tour costs USD 150 to 280 per person in 2026, covers roughly 800 kilometres of salt flat and high desert in a shared 4x4, and — this is the part most people do not realise when they book — spends only the first morning on the Salar de Uyuni itself. Days two and three climb south into the Reserva Nacional de Fauna Andina Eduardo Avaroa, a 7,147 km² protected area that never drops below 4,200 m. That is where the red lagoon, the flamingos and the geysers are. Here is what actually happens on each of those three days, what it costs, and the handful of questions worth asking an agency before you hand over money.
What the 3-day circuit actually covers
Almost every agency in Uyuni sells a near-identical route, because there is essentially one road network through the Lípez region and the refuges are fixed. You will be in a Toyota Land Cruiser with a driver-guide and five other passengers, sleeping in basic shared lodgings, and eating meals your driver cooks at the back of the vehicle.
The rhythm goes like this: day one is the salt flat, day two is the long haul south through desert and lagoons, and day three is a pre-dawn run to the geysers and hot springs before either returning to Uyuni or crossing into Chile.
What you are paying for is not luxury. It is a driver who knows which of a dozen unmarked tracks is passable this week, and a vehicle that will not strand you at 4,500 m.
Day one — Salar de Uyuni
You leave Uyuni around 10:30. First stop is the Cementerio de Trenes, the rusting locomotive graveyard on the edge of town, then Colchani, where salt is still harvested by hand and the souvenir stalls sell llama-wool everything.
Then the salt. The Salar opens up flat to the horizon in every direction, and this is where the perspective photos happen — your driver will have props and a practised eye. Lunch is usually on Isla Incahuasi, the coral outcrop covered in giant cactus that rises out of the salt (30 bolivianos entry, paid separately). Sunset is on the flat itself, then you drive to a salt hotel in San Juan or Chuvica for the night, at around 3,660 m.
Day two — the long climb into the reserve
This is the hardest and best day. It is eight to ten hours of driving, and you gain almost a kilometre of altitude.
You cross the Chiguana salt pan, pass the Ollagüe volcano viewpoint on the Chilean border, and then run the chain of altiplanic lagoons — Cañapa, Hedionda, Chiarkota, Honda — each holding flamingos feeding in shallow, mineral-heavy water. Three species live here: the James’s flamingo, the Andean flamingo and the Chilean flamingo.
After lunch comes the Desierto de Siloli and the Árbol de Piedra, a wind-carved rock that looks exactly like a stone tree, and then the reserve gate, where you pay the 150-boliviano entrance fee in cash.
The day ends at Laguna Colorada, and it is worth understanding what you are looking at. The lagoon sits at 4,278 m, covers 60 km², and averages just 0.35 metres deep — you could walk across most of it. Its colour comes from red sediments and Dunaliella salina, a pigmented alga that thrives in hypersaline water. Late afternoon, when the wind picks up and stirs the sediment, is when the red is deepest. It has been a Ramsar Wetland of International Importance since 27 June 1990.
The second night is the one people remember, and not always fondly. The refuges near Laguna Colorada sit above 4,200 m with no heating, and in winter the temperature inside your room can drop below freezing. It passes. Sunrise the next morning makes up for it.
Day three — geysers, hot springs and the border
You will be woken around 04:30. This is not sadism: the Sol de Mañana geothermal field is at its most dramatic in the cold pre-dawn air, when the temperature differential makes the steam columns tower.
Sol de Mañana sits at about 4,900 m and spreads across 10 km² of fumaroles, boiling mud pools and steam vents. The fumaroles reach 70 °C, fed by underground reservoirs at 250 to 260 °C. There are no railings and no marked paths. Stay behind your driver and walk only where the ground is dry and pale — the darker, damp crust is thin.
From there it is a short drive down to the Termas de Polques, natural hot springs at around 4,400 m where you can sit in 30-something-degree water looking across the Salar de Chalviri. Bring your swimsuit in your day bag, not in the roof luggage.
The last stop is Laguna Verde, a mineral lake at roughly 4,300 m below the near-perfect cone of the Licancabur volcano on the Chilean border. Its colour shifts from pale turquoise to deep emerald depending on how much wind has stirred the arsenic-bearing sediments — on a still morning it can be almost grey, so this one is genuinely luck-dependent.
Then either the long drive back to Uyuni, arriving around 18:00, or the drop at the Hito Cajón border post for San Pedro de Atacama.
What it costs in 2026
| Item | Cost |
|---|---|
| Shared 3-day tour (basic to mid-range) | USD 150–280 |
| Eduardo Avaroa reserve entrance | 150 Bs (≈ USD 15) |
| Isla Incahuasi entrance | 30 Bs (≈ USD 3) |
| Hot springs entry | 20–30 Bs |
| Sleeping bag rental | 30–50 Bs |
| Tip for the driver-guide | 50–100 Bs per passenger |
Two notes on money. First, entrance fees are almost never included — always ask. Second, Bolivia moved to a floating exchange rate in late June 2026, so the boliviano-to-dollar figures above shift; check the day’s rate. There is no ATM anywhere on the circuit after you leave Uyuni, so bring all the cash you need in small notes.
How to get to Uyuni
The overnight bus from La Paz takes 10 to 12 hours and costs 100 to 250 bolivianos depending on whether you take a cama service. From Sucre it is around 8 hours. Flying into Uyuni’s Joya Andina airport from La Paz takes under an hour and runs USD 80 to 150. Coming from San Pedro de Atacama, most travellers do the circuit in reverse as a Chile-to-Bolivia crossing.
Choosing an operator without getting burned
Prices cluster tightly, which means a quote well below the pack is buying you something worse — usually an older vehicle or a driver working his third consecutive circuit without rest. Ask these four things:
- Are entrance fees included? The single biggest hidden cost.
- How many passengers per vehicle? Six plus the driver is standard. Seven is uncomfortable for three days.
- Does the driver speak English? Most do not. If that matters, pay for it explicitly; do not assume.
- Is there oxygen in the vehicle? A reputable operator carries a bottle. Ask to see it.
Book in person the day before if you can. Agencies on Avenida Ferroviaria in Uyuni will show you the actual Land Cruiser, and you can tell a great deal from whether the tyres have tread.
Altitude, and taking it seriously
You sleep at 3,660 m on night one and above 4,200 m on night two, after a day spent between 4,000 and 4,900 m. If you fly into La Paz and go straight to Uyuni, you are stacking altitude on altitude with no adaptation. Give yourself at least two nights above 3,000 m first — La Paz, Sucre or Potosí all work.
On the tour: drink far more water than feels necessary, skip alcohol entirely, eat lightly, and chew coca leaves or drink the tea when your driver offers. If a headache worsens rather than eases overnight, tell your driver. Descending is always possible and always the right call.
What to pack
Layers, and more of them than you think. A down jacket, thermal base layers, hat and gloves for the mornings; sunglasses and factor 50 for the middle of the day, when the salt and the thin air will burn you in twenty minutes. Add a swimsuit and quick-dry towel for Polques, wet wipes because showers are scarce and often cost extra, a power bank since electricity in the refuges runs on a generator for a few evening hours, and toilet paper.
Bring your passport. You will need it at the reserve gate and at the Chilean border if you are crossing.
Is it worth three days?
There is a one-day salt flat tour, and if you are short on time it delivers the mirror shot and the perspective photos perfectly well. But the salt flat is the famous part of southwest Bolivia, not the strangest part. The strangest part is the second afternoon, when you come over a rise at 4,300 metres and see a lagoon the colour of rust, filled with flamingos, ringed by white borax islands, with nothing else in any direction for a hundred kilometres. That is worth the cold night.

Frequently asked questions
Is the Eduardo Avaroa reserve entrance fee included in the tour price? +
Usually not, and this is the single biggest source of confusion when comparing quotes. The 150-boliviano reserve fee and the 30-boliviano Isla Incahuasi fee are almost always paid separately, in cash, on the day. Ask the agency directly whether entradas are included before you compare two prices, because a USD 180 tour that includes fees is cheaper than a USD 170 tour that does not.
How cold does it get on the second night of the Uyuni tour? +
Very cold. The night-two lodging sits near Laguna Colorada at over 4,200 m, and between May and August the temperature routinely drops below minus 15 °C after dark. Most refuges have no heating and electricity shuts off around 21:00. Sleep in thermal layers, a hat and socks, ask for a second blanket on arrival, and keep your phone and camera batteries inside the sleeping bag with you.
Can I finish the 3-day tour in San Pedro de Atacama instead of returning to Uyuni? +
Yes. On the morning of day three most operators can drop passengers at the Hito Cajón border post near Laguna Verde instead of driving back to Uyuni, with a transfer onward to San Pedro de Atacama in Chile. Say so when you book, not on the day, since it changes the vehicle's return load. Expect a small surcharge and remember Chile bans bringing in fresh food, seeds and coca leaves.
What is the best month to do the Uyuni 3-day tour? +
It depends on what you want. From November to March, rain leaves a thin film of water on the salt flat and creates the mirror effect, but tracks in the reserve can flood and some lagoons become unreachable. From May to September the roads are reliable, skies are cleanest and flamingo viewing is good, but nights are brutally cold. April and October are the quiet compromise months.
