The Salar de Uyuni is the world’s largest salt flat — roughly 10,582 square kilometers of blinding white crust in southwestern Bolivia, so vast and so flat that NASA has used it to calibrate satellite instruments. What it looks like when you get there depends entirely on the season: in the rainy months, a thin layer of water turns the entire flat into a mirror that erases the horizon; in the dry season, the water disappears and leaves behind a landscape of naturally occurring salt hexagons stretching in every direction. Either way, it’s one of the most genuinely otherworldly places most travelers will ever stand.
How to Get There
- By air: Flights connect La Paz to Uyuni’s airport (UYU) in about an hour, with 1–2 flights daily.
- By overnight bus: From La Paz, roughly 10–12 hours; a reclining “cama” seat makes this a reasonably bearable budget option.
- By train: From Oruro, around 7 hours — one of the more scenic ways in, though you still need to get to Oruro first.
- From Chile: A popular alternative is joining a 3-day cross-border tour from San Pedro de Atacama, arriving into Uyuni on the final day rather than starting from the Bolivian side.
- Tours themselves depart from Uyuni town, a small base of around 5,000 people that exists almost entirely to service salt flat tourism.
Best Time to Visit
- December–April (rainy season), peak February–March: The famous mirror effect — a thin layer of water reflects the sky perfectly, creating the reflection photos the Salar is best known for.
- May–October (dry season): No mirror, but easier driving conditions and access to Isla Incahuasi, which can flood out during the wet months. This is also when the salt’s natural hexagonal patterns are most visible.
- There’s no wrong season here — the two versions of the Salar look completely different, and both are genuinely photogenic. Choose based on which look you want, not which season is “better.”
How Many Days to Stay
- 1 day covers the core highlights: the salt flat itself, the Train Cemetery, Colchani, and (dry season) Isla Incahuasi.
- 3 days extends into the Eduardo Avaroa Andean Fauna National Reserve — colored lagoons (Laguna Colorada, Laguna Verde), geysers, hot springs, and flamingo colonies — and is the classic full circuit most photos online are showing.
Things to Do
- The salt flat itself — walking or driving out into the endless white expanse, including the classic perspective/forced-scale photos the Salar is famous for.
- Isla Incahuasi — a rocky, cactus-covered “island” in the middle of the flat, accessible in the dry season.
- The Train Cemetery — a rusting graveyard of 19th- and early 20th-century steam locomotives just outside Uyuni town.
- Salt hotels — several accommodations near the flat are built almost entirely from salt blocks.
- Colored lagoons (3-day tours) — Laguna Colorada and Laguna Verde, both striking mineral-tinted lakes, and both home to pink flamingos, vicuñas, Andean foxes, and vizcachas.
- Sol de Mañana geysers and hot springs (3-day tours) — typically visited at sunrise on the final day of the circuit.
Where to Stay
| Type | Notes |
|---|---|
| Uyuni town hostels/hotels | Base for day tours and the start/end point for multi-day circuits |
| Salt hotels (on tour) | Distinctive accommodation built from salt blocks, typically included in multi-day tour packages |
| Basic refugios (3-day tours) | Budget multi-day tours use simple shared lodging along the route — set expectations accordingly |
Costs
| Item | Approximate Price | Notes |
|---|---|---|
| Shared day tour | ~420–650 BOB (US$60–95) | Covers the Train Cemetery, Colchani, salt hexagons, and Isla Incahuasi |
| 3-day shared tour | ~1,050–2,300 BOB (US$150–330) | Wide range reflects operator/vehicle/lodging quality — budget end uses basic shared refugios, higher end includes better vehicles and salt-hotel nights. Private or luxury multi-day tours run considerably higher (US$500+) |
| Isla Incahuasi entry | ~30 BOB | Not included in most tour prices — pay on site |
| Eduardo Avaroa Reserve entry | ~150 BOB | Cash only, required for 3-day circuit routes |
| Hot springs/showers | Small extra fee (a few BOB) | Cash only |
⚠️ Note: Tour prices below change often and vary significantly by operator and season — confirm current rates directly with Uyuni-based operators before booking.
Money-saving tip: Book tours locally in Uyuni town rather than online in advance — online prices can run notably higher for the same itinerary.
Cash tip: Carry 200–300 BOB in small bills for entrance fees, snacks, and tips — there are no ATMs once you leave Uyuni town, and guides/drivers are typically tipped 50–100 BOB on multi-day tours.
Safety
- Altitude: The Salar itself sits at ~3,656m, similar to La Paz, but 3-day circuits climb higher — Laguna Colorada and the geyser fields reach 4,800m+. Acclimatize before joining a multi-day tour. See our Altitude Sickness guide.
- Cold nights: Temperatures can drop well below freezing overnight, even though days are often sunny — this catches travelers off guard more than almost anything else on this trip.
- Don’t attempt an unguided visit. The salt flat has no roads, markers, or fixed landmarks — GPS-only navigation is genuinely difficult, vehicles can get stuck, and there’s no rescue infrastructure out on the flat. A 4×4 tour with an experienced driver is effectively mandatory, not just a convenience.
- Choose a reputable operator. Tour quality (vehicle maintenance, driver experience) varies significantly, especially at the cheapest end of the market — this is one destination where the cheapest option carries real practical risk, not just a comfort trade-off.
- Sun exposure: At this altitude and with the salt’s reflective glare, sunburn happens fast even on cool days.
Altitude Information
The Salar itself sits at approximately 3,656m, comparable to La Paz. If you extend to the 3-day circuit, expect to reach considerably higher elevations — over 4,800m near Laguna Colorada and the geysers. Acclimatize with a few days elsewhere in Bolivia’s highlands before attempting the multi-day route. See our full Altitude Sickness guide.
Good to Pack
- Sunscreen and sunglasses — glare off the salt is intense, even on overcast days
- Lip balm — the combination of altitude, sun, and dry air is hard on lips and skin
- Layers of clothing — daytime warmth and near-freezing nights require genuine layering, not just a jacket
- Snacks and water, especially for multi-day tours where options are limited
- Toilet paper — not always provided along the route
- Cash — small bills, since there’s no ATM access once you leave Uyuni town

Local Food to Try
Uyuni isn’t a culinary destination the way some other Bolivian cities are — most travelers eat meals included in their tour package, which typically means simple, hearty altiplano staples: quinoa soup, potato and llama meat dishes, bread, and api (a warm, spiced purple corn drink often served at breakfast). Salt hotels along the route occasionally offer a more memorable setting for these included meals, with tables and chairs built from salt blocks.
If you have time in Uyuni town itself before or after your tour, the dining scene leans toward simple tourist-friendly spots — pizzerias, cafes, and a handful of places serving traditional Bolivian plates like picante de pollo or Argentine-style steak, reflecting the town’s proximity to the Argentine border. The Central Market and street vendors near the main plaza are the most affordable options for a quick meal or snack like salteñas or empanadas.
FAQ
Should I visit in the wet season or dry season?
Depends what you want to see — wet season (Dec–Apr, peak Feb–Mar) gives you the famous mirror effect; dry season (May–Oct) gives you the salt’s natural hexagon patterns and easier access to Isla Incahuasi. Both are genuinely striking; neither is objectively “better.”
Can I visit the Salar de Uyuni without a tour?
It’s not recommended. There are no roads or landmarks on the flat itself, navigation is genuinely difficult, and there’s no rescue infrastructure if something goes wrong. A guided 4×4 tour is the practical standard, not just an upsell.
Should I do a 1-day or 3-day tour?
The 1-day tour covers the core highlights (salt flat, Train Cemetery, Isla Incahuasi) efficiently and suits travelers short on time or altitude tolerance. The 3-day circuit adds the colored lagoons, geysers, and hot springs of the Eduardo Avaroa Reserve, and is the more complete experience if you have the days and the altitude tolerance for it.
How cold does it get at night?
Temperatures on multi-day tours can drop well below freezing overnight, even when days are sunny and warm — pack genuine cold-weather layers, not just a light jacket.
Are there ATMs near the salt flat?
No — withdraw cash in Uyuni town before heading out. There’s no ATM access once you leave, and several entrance fees (Eduardo Avaroa Reserve, Isla Incahuasi) are cash-only.
