The Salar de Uyuni is the largest salt flat on Earth: more than 10,000 km² of white crust at around 3,650 metres (12,000 ft) on the Bolivian altiplano. On a motorcycle it feels like nowhere else. The horizon disappears, there is no sense of distance and it is like riding across a sheet of paper that never ends.
It also asks for more preparation than the photos suggest. Altitude affects both rider and bike, salt eats metal, the season completely changes what you will see, and Bolivia has its own rules for foreign-plated vehicles. This guide covers what you need to know to ride the Uyuni salt flats and come back in good shape.
How to reach the Uyuni salt flats by motorcycle
There are three main gateways, and how you combine them defines the trip.
From Chile via the Atacama and Paso de Jama
The most popular route. From San Pedro de Atacama the road climbs quickly across the Chilean altiplano to Paso de Jama, above 4,000 m, and descends into northern Argentina (Purmamarca and Humahuaca). From there you enter Bolivia at La Quiaca–Villazón and ride via Tupiza to Uyuni — Atacama, the Quebrada de Humahuaca and the salt flat in a single trip.
From Chile via Ollagüe
The most direct link between Calama and Uyuni, through the Ollagüe–Avaroa border. The Bolivian side has long dirt and sand sections with no services. It is a proper adventure crossing, best done as a return route and with support.
From Argentina via La Quiaca
Coming up through northern Argentina (Salta and Jujuy), you cross at Villazón and reach Uyuni via Tupiza, on a road that is paved for much of the way.
Best time to ride the Salar de Uyuni
| Period | What the salt flat looks like | For riding |
|---|---|---|
| December–March (rainy season) | Thin layer of water: the famous mirror effect | Poor. Salt water, closed areas and flooded dirt access roads |
| April–May | Drying out, crust returning, patches of mirror at the edges | Good window: clear skies, moderate cold |
| June–August (winter) | Dry, sharp salt hexagons | Possible, but nights well below freezing |
| September–October | Dry, firm crust | Good window: milder days, afternoon wind |
| November | Dry, with a risk of early rain late in the month | Possible |
For riding on the salt, the sweet spots are late March to April and September to October — the windows ROXMOTORS uses for its Atacama and Uyuni Salt Flats Motorcycle Tour. The mirror effect is stunning, but if that photo is a priority, it is usually better done on a 4×4 excursion than on a bike.
Altitude: what changes for you and the bike
The classic route through the Atacama goes from San Pedro (about 2,400 m) to over 4,000 m in a single day, then stays above 2,900 m for several days: Humahuaca, Tupiza and Uyuni at about 3,650 m. Altitude sickness — soroche — is the main risk of the trip, and fitness does not protect you from it.
How do you avoid altitude sickness?
- Acclimatise before climbing. Two days in San Pedro de Atacama before Paso de Jama make a real difference.
- Drink plenty of water and skip alcohol for the first nights at altitude.
- Eat light and sleep well. A severe headache, nausea or breathlessness at rest are signs to descend or get help.
- Talk to your doctor before the trip about preventive medication, especially with any heart or respiratory history.
And the bike?
Engines lose power in thin air. Fuel injection adjusts the mixture automatically, but you will feel weaker roll-on above 4,000 m. Leave more room for overtaking than usual.
Riding on salt: what nobody tells you
- Navigation: there are no roads, signs or landmarks on the salt. Tracks left by 4x4s help, but it is easy to lose your bearings. Do not ride onto the salar without a loaded GPS track or a local guide.
- Corrosion: salt sticks to everything and attacks the chain, brakes and bare metal. Wash the bike — underneath too — as soon as you leave the salt, then lube the chain.
- “Ojos de sal”: small holes in the crust with water underneath that can catch a wheel. Stay on established tracks.
- Glare: sunlight on white is intense. Sunglasses, a UV-rated visor and sunscreen are essential.
- The edges: the transition from dirt to salt often has saline mud, even in the dry season. That is where most bikes get stuck.
What to see at the Salar de Uyuni
- Colchani: a village on the edge of the salt flat where salt is still extracted and processed by hand.
- Dakar monument and the Plaza of Flags: landmarks from the rally’s years in Bolivia, near the main entrance to the salar.
- Salt hotels: walls, beds and tables built from salt blocks. Spending a night in one is part of the experience.
- Isla Incahuasi: a rocky island in the middle of the flat, covered in giant cacti, with white in every direction.
- Train Cemetery: early 20th-century locomotives abandoned just outside Uyuni.
- Tupiza: red canyons straight out of a Western, on the way up from Argentina.
Riding Bolivia: visas, fuel and the border
Do I need a visa for Bolivia?
It depends on your passport. Most EU citizens, as well as UK, Canadian and Australian nationals, have historically entered Bolivia visa-free as tourists, while US citizens have needed a visa. Bolivia’s rules have changed more than once, so check the current requirement for your nationality before booking.
How much is fuel in Bolivia for foreign vehicles?
Foreign-plated vehicles pay a different price from Bolivian ones. In January 2026, Bolivia’s hydrocarbons agency (ANH) set petrol for foreign plates at Bs 8.68 per litre. Bolivia has also had periods of fuel shortages in some regions in recent years — top up whenever you can and do not count on stations in remote stretches.
How does the border work with a motorcycle?
Bolivian customs registers a temporary import for the bike, which has to leave the country within the time granted. Bring the original registration and, if the bike is not in your name, the owner’s authorisation. On a rental, cross-border permission has to be arranged by the rental company in advance — without it, the bike cannot leave its home country. Our guide to riding South America as a foreigner covers the paperwork in more detail.
Independent or guided?
You can ride to Uyuni independently, but it is the South American trip where support makes the biggest difference: altitude, long stretches without services, navigation on the salt and three borders in a few days.
On a Fly & Ride trip you fly into Antofagasta, Chile, and the bike is waiting. The ROXMOTORS Atacama and Uyuni Salt Flats tour covers the route in 10 days: two acclimatisation days in San Pedro (Valle de la Luna, the altiplanic lagoons and El Tatio geysers), Paso de Jama, Humahuaca, Tupiza, a night in a salt hotel, a full day exploring the salar and a return through Chile. You ride a Triumph Tiger 900 with fuel included, a support vehicle, a guide trained in mechanics and wilderness first aid, and the border paperwork handled.
Short on time? The 6-day Atacama Desert tour focuses on the Chilean desert without crossing into Bolivia.
Uyuni salt flats by motorcycle: FAQ
Can you ride a motorcycle on the Salar de Uyuni?
Yes. Motorcycles and 4x4s use the tracks across the salt in the dry season. In the rainy season parts of the flat flood and access is restricted. In any season, ride with a guide or a reliable GPS track.
What is the altitude of the Salar de Uyuni?
About 3,650 m (12,000 ft). On the route from Chile, Paso de Jama is above 4,000 m and the Chilean road leading up to it climbs higher still.
Does salt damage the motorcycle?
It speeds up corrosion if left on the bike. Washing it soon after leaving the salar, including underneath, and lubing the chain solves most of the problem.
Do I need off-road experience?
Not for the salt itself: in the dry season the crust is firm and flat. Experience helps on the dirt access roads and muddy edges. On the ROXMOTORS route, around 95% of the distance is paved.
How many days do you need?
On a Fly & Ride from Chile, 10 days lets you combine the Atacama, northern Argentina and the salt flat with proper acclimatisation.
Is it cold at the Salar de Uyuni?
Days are usually sunny and mild, but nights are cold all year and well below freezing in winter. Pack thermal layers even for April or September.
The most beautiful white on Earth
The Salar de Uyuni is one of those places a photo cannot explain. With the right season, proper acclimatisation and good support, it becomes the highlight of any South American ride. See the upcoming Atacama and Uyuni departures and pick your window.
