Quick Summary: At 10,582 km², Salar de Uyuni is larger than Lebanon, roughly the size of Jamaica, and bigger than Yellowstone National Park. It’s about seven times the area of Greater London and around thirteen times New York City. It’s also larger than Lake Titicaca, which most travelers cross on the way here. Those comparisons matter for planning, because they explain why a single day tour reaches only one section of the flat and why the classic 3-day circuit covers hundreds of kilometres.
“10,582 square kilometres” doesn’t mean much until you put it next to something you’ve stood on. The whole problem with photographing the Salar is that it offers no scale reference — and the whole problem with describing it is the same. So here it is measured against places people actually know.
Salar de Uyuni vs countries and territories
| Place | Area | Compared to Uyuni |
|---|---|---|
| Qatar | about 11,600 km² | Slightly larger |
| Jamaica | about 10,990 km² | Almost exactly the same |
| Kosovo | about 10,890 km² | Almost exactly the same |
| Salar de Uyuni | 10,582 km² | — |
| Lebanon | about 10,450 km² | Slightly smaller |
| Cyprus | about 9,250 km² | Smaller |
| Puerto Rico | about 9,100 km² | Smaller |
| Delaware and Rhode Island combined | about 10,450 km² | Slightly smaller |
The Jamaica comparison is the one that tends to land. An entire Caribbean nation — mountains, cities, coastline, three million people — fits into the footprint of a flat white plain in southwest Bolivia with no permanent residents on it.
Salar de Uyuni vs national parks and famous natural sites
| Place | Area | Compared to Uyuni |
|---|---|---|
| Serengeti National Park, Tanzania | about 14,750 km² | Larger |
| Salar de Uyuni | 10,582 km² | — |
| Yellowstone National Park, USA | about 8,990 km² | Uyuni is about 18% larger |
| Grand Canyon National Park, USA | about 4,930 km² | Uyuni is more than twice the size |
| Yosemite National Park, USA | about 3,030 km² | Uyuni is about 3.5 times larger |
| Lake District National Park, UK | about 2,360 km² | Uyuni is about 4.5 times larger |
Yellowstone is a useful benchmark because most people have a mental image of it as enormous. Uyuni is bigger — and unlike Yellowstone, it is essentially one continuous feature rather than a park containing many.
Salar de Uyuni vs cities
| City | Area | How many fit into Uyuni |
|---|---|---|
| Greater London | about 1,570 km² | Around 7 |
| Los Angeles | about 1,300 km² | Around 8 |
| Hong Kong | about 1,110 km² | Around 9.5 |
| New York City | about 784 km² | Around 13.5 |
| Singapore | about 735 km² | Around 14 |
If you’ve ever driven across a major metropolitan area and felt the distance, multiply it. Then remove every building, road sign and landmark, and you have some sense of what a driver is navigating across when they take you toward Isla Incahuasi.
Salar de Uyuni vs places on the Peru–Bolivia route
Most travelers reaching the Salt Flats have just come down through Peru, so these are the comparisons that will feel most immediate:
- Lake Titicaca covers roughly 8,300 km² and sits at about 3,810 m. The Salar is larger in area and only slightly lower — around 3,656 m.
- The Machu Picchu Historic Sanctuary covers roughly 326 km². Uyuni is more than thirty times its area.
- Colca Canyon runs about 70 km in length. The Salar is wider than that in more than one direction.
- La Paz sits at about 3,640 m — almost exactly Uyuni’s elevation, which is why travelers who acclimatize properly in La Paz usually cope well on the Salt Flats.
If you’re planning the full overland route through both countries, our guide on how to get to Salar de Uyuni covers the connections from Peru, Chile and Argentina.
Salar de Uyuni vs other salt flats
This is where the “largest in the world” claim needs a bit of honest nuance.
| Salt flat | Country | Approximate area |
|---|---|---|
| Makgadikgadi Pans (a complex of several pans) | Botswana | around 16,000 km² |
| Salar de Uyuni (single continuous salt flat) | Bolivia | 10,582 km² |
| Chott el Djerid | Tunisia | around 7,000 km² |
| Salinas Grandes | Argentina | around 6,000 km² |
| Etosha Pan | Namibia | around 4,760 km² |
| Salar de Coipasa | Bolivia | around 2,220 km² |
| Bonneville Salt Flats | USA | around 120 km² |
Makgadikgadi is frequently cited as larger, but it is a system of separate pans rather than one unbroken surface. Salar de Uyuni is the largest single continuous salt flat on Earth, and it is also far flatter than any of the others — its elevation varies by roughly a metre across the entire surface, which is why it’s used as a calibration reference for satellites in orbit.
The Bonneville comparison is the most striking on the list. The famous American salt flats used for land-speed records are roughly one percent of Uyuni’s area.
What all this means for your trip
The size isn’t an abstract fact — it’s the reason your itinerary looks the way it does.
- A 1-day tour covers one corner. Roughly eight hours, taking in the Train Cemetery about 3 km from town, Colchani at around 22 km, a stretch of open flat, and usually Incahuasi or a sunset spot. That’s a real experience of the Salar, but it is a slice.
- Isla Incahuasi is about 80 km out, roughly two hours of driving across salt each way. That single stop is why day tours run long.
- The southern lagoons are a different landscape entirely. Laguna Colorada, the Sol de Mañana geysers at close to 4,900 m, the Polques hot springs and Laguna Verde sit hundreds of kilometres south in the Eduardo Avaroa Reserve. They are reachable on a 3-day or 4-day circuit and not on a day trip.
- You will spend a lot of hours in a Land Cruiser. That’s not a complaint about the tours; it’s arithmetic.
| If you have | You realistically see | Suits |
|---|---|---|
| 1 day | The salt flat itself, one section | Travelers short on time |
| 3 days / 2 nights | The flat plus lagoons, geysers, desert and hot springs | Travelers who want the whole landscape |
| 4 days | The above, plus the crossing to or from San Pedro de Atacama | Travelers continuing into Chile |

FAQ
Can you see Salar de Uyuni from space?
Yes. Its size combined with the brightness of the salt crust makes it clearly visible in satellite imagery — it reads as a large white plate on the Bolivian Altiplano. Its exceptional flatness has also made it genuinely useful to space agencies as a reference surface for calibrating satellite altimetry instruments, which is a rare case of a tourist attraction doubling as scientific equipment.
Is the whole salt flat accessible to visitors?
No, and not because of restrictions — because of practicality. Tours use established routes across sections of the flat that drivers know well, avoiding “ojos de sal”, the brine spring holes that can trap a vehicle. Vast areas of the Salar are simply never driven on. In the wet season, accessible territory shrinks further as flooding closes routes and can cut off Isla Incahuasi entirely.
How does the altitude compare to other places I’ll visit?
Uyuni town sits at 3,670 m and the flat at 3,656 m, which puts it slightly above Cusco (about 3,400 m) and roughly level with La Paz (about 3,640 m) and Lake Titicaca (about 3,810 m). If you’ve already spent nights at those altitudes you should be reasonably adjusted. The section that catches people out is the southern circuit, where the Sol de Mañana geysers sit close to 4,900 m — noticeably higher than anything on the standard Peru route.
Does the salt flat change size during the year?
The salt crust itself doesn’t change size, but the usable and visible surface does. In the wet season, water pools across large areas, and the flooded portion expands and contracts with rainfall. Some travelers describe the wet-season Salar as feeling larger because the reflection erases the horizon completely and there’s no visual boundary at all. In the dry season the edges are clearly defined and you can see the surrounding mountains, which paradoxically makes it feel more contained.
Limitations
Area figures for countries, parks and salt flats vary depending on the source and whether inland water, buffer zones or adjacent basins are included — the numbers here are standard reference figures rounded for comparison, not survey-grade measurements. This is particularly true of salt flats, where different studies draw boundaries differently; Salinas Grandes and Makgadikgadi are both quoted across wide ranges. Distances and driving times on the Salar are typical dry-season figures and lengthen in the wet season. Tour routes and accessible areas are determined locally by conditions on the day, so confirm the specific stops on any itinerary before booking.
