Salar de Uyuni Self-Drive: Southwest Bolivia Route

Salar de Uyuni by car: a southwest Bolivia route

The Salar de Uyuni and the Altiplanic Lagoons form the most surreal driving destination in South America. In few places in the world does the scenery change so much in three days. You leave an infinite salt desert, pass by red lagoons with flamingos, cross rock formations sculpted by the wind, sleep at nearly 5,000 meters of altitude and finish crossing the Chilean border between snowy volcanoes. It's a circuit you do in a few days, but that delivers more scenery than a two-week trip to a conventional destination.

Most tourists do southwest Bolivia on a 4x4 tour hired with a driver, leaving from Uyuni, Tupiza or San Pedro de Atacama. That's a valid option, especially for whoever doesn't have an appropriate vehicle. But for the Brazilian overlander with their own 4x4, doing it on your own is a completely different experience. You decide the pace, the stops, the overnight, and the route becomes part of the larger trip instead of an isolated package. This article is for that scenario.

In short: the classic circuit is 3 to 5 days between Uyuni and San Pedro de Atacama (Chile), passing through the Salar, the Altiplanic Lagoons, Sol de Mañana, Laguna Colorada and Laguna Verde. Vehicle: a 4x4 with good clearance is practically mandatory: deep sand, severe ripio, altitude above 4,500m at several points. Extra fuel (a 20-40 liter jerrycan) is the rule. Ideal window: May to November (dry season). January to March has the Salar as a "mirror" but stretches become impassable.

How to get there: which border to use

Three main entries, and the choice changes the logistics of the larger trip a lot:

Via Argentina, La Quiaca/Villazón (south): the most used entry by the Brazilian overlander. You go up through northern Argentina (Salta, Jujuy, La Quiaca), cross the border at Villazón, drive to Tupiza (3h) and from there go up to Uyuni (another 4-5h of ripio).

Via Argentina, Bermejo/Pocitos (further east): less touristy, it leads to Tarija and then Potosí before Uyuni. Worse roads, takes more days.

Via Chile, San Pedro de Atacama to Hito Cajón: for whoever is doing the Argentina to Chile to Bolivia circuit, this is the way to enter from the "high" side (already at altitude) and go down to Uyuni. Crossing Hito Cajón requires a vehicle in order and good planning.

The most common choice: enter through Argentina (Villazón), leave through Chile (Hito Cajón), cross the whole southwest without going back the same way.

Day-by-day itinerary

Day 1: Uyuni and the Salar

Leaving Uyuni town in the morning, cross the Salar on the Colchani side (the tourist entrance). Stop at the Salt Hotel (a museum), the Flags of the world (a classic photo stop) and continue to Isla Incahuasi (giant cacti in the middle of the salt flat, an iconic landscape).

Most of the day is spent driving on the infinite white crust, a sensation that few places in the world deliver. Overnight in Tahua or Coqueza (small villages on the north edge of the Salar with basic lodging). Alternative: a more structured salt hotel in Colchani.

Day 2: Salar to San Cristóbal / San Pedro de Quemes

Leave the Salar, go down to San Cristóbal (a mining town with a preserved old church) or San Pedro de Quemes (a smaller village, closer to the circuit). A free afternoon.

This day is more of a transition. It's worth taking advantage of it to refuel, buy water and supplies: from here on, infrastructure disappears.

Day 3: Altiplanic Lagoons

A day of mind-blowing scenery. Laguna Hedionda (with flamingos), Laguna Cañapa, Laguna Charcota, Árbol de Piedra (a rock formation sculpted by the wind, on a sand plain), and finally Laguna Colorada, a red lake with flocks of pink flamingos. Overnight at the Huayllajara refuge or in Quetena Chico.

The altitude starts to pinch: everything above 4,200m. It can be the first day of a strong headache if you didn't acclimatize well.

Day 4: Sol de Mañana, hot springs and Laguna Verde

Departure before dawn for Sol de Mañana (a geyser field at 4,850m, steam coming out of the earth from the cold). Breakfast at the Termas de Polques (a hot-water bath at 4,400m, with a view of the cordillera). Afternoon at Laguna Verde (greenish from the arsenic, with the Licancabur Volcano in the background).

Final overnight at a refuge near Laguna Verde, or go straight down to the Chilean border.

Day 5: Hito Cajón border and Atacama

Cross the border at Hito Cajón (a simple procedure, but at altitude, the office at 4,500m), go down to San Pedro de Atacama (Chile, ~2,400m). A brutal drop in altitude, a strong physical sensation of recovery.

Vehicle, altitude and fuel

Vehicle. A 4x4 is practically mandatory. There are stretches of deep sand, severe ripio, small water crossings in some periods. A high SUV has a chance, a pickup with 4x4 works well. A motorhome can pass in some parts but is restricted. Many motorhomes can't manage certain stretches. A normal passenger car is not recommended. For that profile, it's better to hire a tour with a local driver.

Altitude. It leaves 3,700m (Uyuni town) and climbs to 4,900m (the geysers). Most of the circuit is above 4,200m. Acclimatize beforehand. Ideally, spend 2-3 days at moderate altitude (Potosí, La Paz, or Argentine Salta) before going up the southwest. Coca leaf, coca tea and constant hydration are the local standard, it's not a fuss, they really help.

Fuel. Critical points: between Uyuni and Tupiza, and during the whole Lagoons circuit. A 20-40 liter extra jerrycan is the rule. An additional caution: Bolivia has dual fuel pricing: a Bolivian pays the subsidized price, a foreigner pays up to 3x more. At small-town stations, the attendant sometimes "negotiates" the price, sometimes refuses to sell. Always carry cash (bolivianos and dollars).

Food and water. From San Pedro de Quemes on, a restaurant is very rare. Carry supplies for at least 3 days.

Bolivia's critical points

Bolivia has peculiarities that the overlander going for the first time needs to know:

Green Card in Bolivian format: the international insurance for Bolivia has its own format, different from Mercosur. Confirm with your insurer beforehand.

Cash payments: a card rarely works outside a capital. Bolivianos in cash are the rule. An ATM in a mid-size city is reliable, but Uyuni town has a big line.

Language: basic Spanish is enough, but the local accent is different from Argentina/Chile. In a small village, Quechua/Aymara is the first language.

Non-official charges: at some borders and parks (the Eduardo Avaroa Reserve), there are fees payable in cash. All apparently legitimate, but check before paying amounts that seem high.

FAQ

Can you do the Salar without a 4x4?

You can, but with limits. A passenger car reaches Uyuni town, and in the dry season the most touristy part of the Salar (Colchani to Incahuasi) is even crossable with care. But the Lagoons circuit requires a 4x4, without it, the way is a hired tour.

Is it worth going in the rainy season to see the "mirror" effect?

For a photographer, yes. For a complete trip, complicated: stretches of the Salar and the Lagoons circuit become impassable in heavy rain. A hybrid solution: go in March or early April, the end of the rain, there's still a partial mirror effect and the roads start to open.

Can I do only the Salar and go back, without doing the Lagoons circuit?

You can. The Salar as a day trip from Uyuni takes 1 day. But it's a piece of the experience, whoever goes all the way to Bolivia usually finds it worthwhile to do the complete circuit.

How much does the additional fuel cost?

It varies a lot with the exchange rate and the day's price. The order of magnitude: the extra spending on a jerrycan and dual pricing is a small fraction of the trip's total budget.

Is there a phone signal on the circuit?

In Uyuni town, yes. Outside it, practically zero. Plan: warn family/contacts before entering, take offline GPS, and prepare yourself psychologically to disconnect for 3-5 days.

To wrap up

Southwest Bolivia is the kind of destination that changes the yardstick of what you consider "extraordinary scenery". There's no other place in South America that combines an infinite salt desert, red lagoons with flamingos, geysers at 4,900m and snowy volcanoes in a single circuit of a few days. For the Brazilian overlander, it's also the place where the vehicle's technical preparation fully pays off: whoever arrives well equipped does the trip calmly. Whoever improvises finds out quickly why most people hire a tour.
