Quick Summary: The overnight bus is still the default for La Paz to Uyuni — around 550 km, 9–12 hours, roughly $18–$60 depending on operator, arriving at dawn in time for the 10:00 AM Salt Flats departures. Flying takes about an hour for $80–$150 and is the most reliable option. The train via Oruro is the scenic slow choice. What changed in 2026: a national diesel shortage has cut bus departures, fares rose sharply in January, and the boliviano now floats, so dollar prices move week to week.
This is the last leg between you and the Salt Flats. Most travellers reach La Paz on a Peru Hop or Bolivia Hop pass from Cusco, Puno or Lima — La Paz is as far south as that network runs, so the Uyuni stretch is booked separately. Worth knowing: Bolivia Hop passengers get discounted rates on Salt Flats tours, so sort the tour before you sort the bus.
Four realistic options. Here’s how they compare.
Quick comparison
| Option | Time | Typical 2026 cost | Reliability | Best for |
|---|---|---|---|---|
| Overnight tourist bus | 9–12 hrs | Around $43–$60 | Good, but fuel-affected | Most travelers |
| Overnight local bus | 9–12 hrs | Around $18–$35 | Variable | Budget travelers |
| Flight | About 1 hr | Around $80–$150 one way | Highest | Time-pressed travelers |
| Bus + train via Oruro | Full day | Around $35–$50 | Fixed days only | Scenic slow travel |
| Multi-day overland tour | 3+ days | $250+ | Operator-dependent | Travelers wanting a guided route |
Option 1: The overnight bus
The default, and for good reason. The logic is tidy: leave La Paz after dinner, sleep across the Altiplano, arrive around dawn — which is exactly when Uyuni’s agencies are loading their 4x4s for the 10:00–10:30 AM departures. You save a night’s accommodation and lose no daylight.
Practical details:
- Departures typically run between 8:00 and 10:00 PM, arriving 5:30 to 7:00 AM
- Distance is around 550 km across high open plateau
- Todo Turismo is the long-standing tourist-oriented operator, running bed-style seats with the highest comfort standard on the route, at roughly $43–$60
- Local operators including Panasur, Trans Titicaca and others run cheaper services from around $18–$35
- At La Paz bus terminal, each passenger pays a small terminal fee, currently around 2.5 Bs, before boarding
What to know before you board:
- It gets genuinely cold. You’re crossing high plateau at night. Bring warm layers into the cabin rather than packing them in the hold.
- Choose full-cama over semi-cama if the budget allows. It’s a long night.
- Keep valuables on your person, never in the luggage hold. Bag tampering while passengers sleep has been reported on some local operators.
- Stick with companies that use the main paved route. A few smaller operators occasionally take dirt-road shortcuts, and that’s where the more serious incidents have historically happened.
Best for: first-time visitors, budget travelers, and anyone who wants to arrive in time for a same-day tour.
Option 2: Flying
About an hour in the air against 9–12 hours on the road, typically $80–$150 one way with Bolivian carriers. It’s the most reliable option in a year when road transport isn’t.
The trade-offs: you pay several times the bus fare, you arrive mid-morning rather than dawn so a same-day tour is tighter, and you lose the accommodation saving of a night bus.
Best for: travelers short on time, anyone who’s had enough of overnight buses, and those who can’t afford a cancellation to derail a fixed itinerary.
Option 3: The train via Oruro
This is the one people forget exists. Bolivia’s Ferroviaria Andina runs passenger services on the Oruro–Villazón corridor, and Uyuni is a main stop.
You take a bus from La Paz to Oruro (roughly 3–4 hours), then join the train south. Oruro to Uyuni is roughly 7 hours.
Two services run it:
- Expreso del Sur — the faster, more comfortable service, stopping only at main stations: Oruro, Río Mulato, Uyuni, Atocha, Tupiza and Villazón. Ejecutivo and Salón carriages plus a dining car. Runs southbound Tuesday and Friday.
- Wara Wara del Sur — stops at all twelve stations including Altiplano villages, cheaper, slower. Adds a Popular class. Runs southbound Wednesday and Sunday.
Fares are charged in bolivianos and range from around Bs 20 for short legs up to roughly Bs 170 for the full corridor in Ejecutivo.
Best for: travelers with flexible dates who want the scenic, unhurried version, and anyone continuing south to Tupiza or the Argentine border at Villazón afterwards. Uyuni’s passenger station sits in town, walking distance from the tour agencies, so you can go from platform to tour desk with your bag. Don’t confuse it with the Train Graveyard outside town — that’s a separate site, and a stop on nearly every Salt Flats tour.
Skip this if your dates are fixed — the train runs on set days only, and missing one costs you several.
Option 4: A multi-day overland tour from La Paz
Some operators sell packaged trips from La Paz that bundle the transport and the Salt Flats tour together, typically $250 and up. Two-day and three-day formats exist, usually with overnight buses in both directions.
Best for: travelers who want one booking and no logistics. Cheaper alternative to the same thing: a Bolivia Hop pass into La Paz plus a discounted Salt Flats tour booked through them gets you most of the “one booking” convenience without the $250+ overland premium.
One more thing he missed: you give Uyuni’s altitude as 3,670 m in the altitude note and 3,656 m in the FAQ. Pick one.
Skip this if you’d rather choose your own operator in Uyuni after seeing the vehicles — which is generally where the quality differences actually live.
Be wary of the compressed “same-day return” formats. They exist, and they mean roughly 22 hours door to door with two consecutive overnight buses. The scenery isn’t the problem; the exhaustion is.
What changed in 2026
Three things make older price guidance unreliable:
- Diesel shortage. A national fuel shortage has cut interdepartmental bus fleet operability sharply — reports in mid-August put reduced operability as high as 50%. Expect fewer departures than timetables suggest, fuller buses, and occasional same-day cancellations.
- Fares. A regulatory fare increase in January pushed prices up around 40%, followed by informal surcharges. Old figures are badly out of date.
- Currency. The boliviano moved to a managed float on 29 June 2026 and has traded well above the old fixed rate since. Ask for prices in bolivianos rather than dollars.
Practical response: book one to three days ahead rather than weeks out, confirm by phone, WhatsApp or in person the day before, and build a spare half-day into any itinerary where a missed bus would cost you a flight or a booked tour.
Altitude note
There’s no relief on this journey. La Paz sits at about 3,640 m, El Alto higher still, and Uyuni at 3,670 m — you never descend. If you haven’t acclimatized, an overnight bus is not where you want to discover that. Give La Paz two nights before heading south. More on this in our Salar de Uyuni info page.
FAQ
Can I take the overnight bus and start a Salt Flats tour the same morning?
Yes, and it’s the most common plan. Buses arrive between roughly 5:30 and 7:00 AM, and most Uyuni operators start their daily departures around 10:00–10:30 AM, which leaves time to drop bags, eat breakfast and meet your group. Agencies and hostels will store luggage while you’re on the tour. The one caveat is that you’ll be doing a long day at 3,656 m on a night of broken sleep — fine for most people, harder if you’re not acclimatized.
Is the train better than the bus?
Better for scenery and for the experience; worse for convenience. The train only runs on fixed days, requires you to get to Oruro first, and takes a full day rather than an overnight. If your dates happen to line up and you like train travel, it’s a genuinely memorable ride across the Altiplano. If you’re on a schedule, the overnight bus does the job in your sleep and gets you there in time for a tour.
How much should I expect to pay in total?
Realistically, budget $43–$60 for a comfortable overnight bus each way, or $80–$150 each way to fly. Add the Salt Flats tour itself — roughly $60–$120 for a 1-day tour or $150–$330 for a 3-day circuit — plus cash-only extras including the 150 Bs Eduardo Avaroa Reserve fee on multi-day routes. Because the boliviano is floating, treat every dollar figure as approximate and confirm in local currency.
What if my bus is cancelled because of the fuel shortage?
Operators generally rebook you onto the next available departure, but “next available” can mean the following night in a thinned-out timetable. This is why booking a few days ahead and reconfirming the day before matters more than usual this year, and why you shouldn’t build an itinerary where a single bus is the only thing standing between you and a non-refundable tour or flight. If you’re on a genuinely fixed schedule, flying is worth the premium.
Limitations
Bolivian bus fares, schedules and availability are unusually volatile in 2026 due to the national diesel shortage and January’s regulatory fare increase, and cancellations are more likely than in a normal year. The boliviano has been floating since June 2026, so all dollar figures here are approximate snapshots — confirm prices in bolivianos. Train timetables, running days and fares are set by the Ferroviaria Andina and are subject to change or suspension; always confirm at the ticket office or the operator’s official channels before planning around them. Flight schedules on this route are limited and can be affected by weather at high-altitude airports. Journey times vary with road and weather conditions.
