Quick Summary: Potosí to Uyuni is a paved 204 km ride of about 3.5 to 4 hours, with several daily buses from Potosí’s old interprovincial terminal on Avenida Universitaria. Sucre to Uyuni takes about 8 hours by overnight bus, or you can break the trip in Potosí. Daytime buses from Potosí arrive too late for 10:30 tour departures, so either arrive the day before or take an overnight bus that gets in before dawn.
Many travelers reach the Salar de Uyuni from the south-central colonial cities rather than from La Paz. Sucre and Potosí are both beautiful, both well connected, and both make good warm-up stops before the salt flats.
The catch is timing. The buses are straightforward, but connecting them with a tour that leaves Uyuni at 10:30 takes a little planning. This guide covers the routes, companies, terminals and connections you need for 2026. For other approaches, see our how to get to Salar de Uyuni guide.
Distances, Times and Altitude at a Glance
| Route | Distance | Bus time | Road |
|---|---|---|---|
| Sucre to Potosí | About 156 km | About 3 hrs | Paved |
| Potosí to Uyuni | About 204 km | 3.5–4 hrs | Paved |
| Sucre to Uyuni (direct) | About 360 km | About 8 hrs | Paved, via Potosí |
Altitude matters on this route more than most:
- Sucre sits at about 2,810 m, low enough for most people to feel comfortable.
- Potosí sits at about 4,070 m, one of the highest cities in the world, and noticeably higher than Uyuni.
- Uyuni sits at 3,656 m.
That makes Sucre to Potosí to Uyuni a good acclimatization sequence. A night or two in Potosí means the high points of a 3-day tour, up to about 4,900 m at Sol de Mañana, are less of a shock.
Potosí to Uyuni by Bus
Where buses leave from
This is the detail that catches people out. Buses from Potosí to Uyuni leave from the older interprovincial terminal on Avenida Universitaria, not from Potosí’s newer main bus terminal on Avenida Las Banderas, which handles Sucre and long-distance routes.
Tell your taxi driver “la terminal antigua, para Uyuni” to avoid going to the wrong one.
Companies and schedules
Several companies run the route, with departures spread from early morning to late evening.
| Company | Typical departures from Potosí | Arrival in Uyuni |
|---|---|---|
| Trans Turismo ZC American | 07:00, 11:00, 18:30 | About 4 hrs later |
| Trans ATL Grevalug | 09:00, 15:00, 20:30 | About 4 hrs later |
| Línea Emperador | 12:30, 19:00, 21:00 | About 4 hrs later |
| Expreso 11 de Julio | Daily | About 4 hrs later |
These times come from Tickets Bolivia’s Potosí to Uyuni listings and change often. Treat them as a guide and confirm at the terminal.
What it costs
Before the September 2026 fuel repricing, Potosí to Uyuni tickets were typically around $8 to $15. After Bolivia removed its diesel subsidy, interdepartmental fares across the country rose by roughly 40% to 100%. Expect to pay more than older guides suggest, and ask for the fare in bolivianos at the window. The Banco Central de Bolivia official rate was Bs 11.90 per dollar on 2 October 2026.
Sucre to Uyuni by Bus
Option 1: The direct overnight bus
Direct buses leave Sucre’s main terminal on Avenida Ostria Gutiérrez in the evening and travel through Potosí to Uyuni overnight.
| Company | Typical departure from Sucre | Typical arrival in Uyuni |
|---|---|---|
| Expreso 11 de Julio | About 20:00 | About 04:00 |
| 6 de Octubre | About 21:00 | About 05:00 |
| Autobuses Emperador | About 22:00 | About 06:00 |
Before the fuel repricing, these lie-flat services started from about $15 to $19. See Tickets Bolivia’s Sucre to Uyuni page for current listings.
What you need to know:
- You arrive in the dark. A 04:00 or 05:00 arrival in Uyuni means several cold hours before tour offices open properly and tours leave around 10:30.
- It is cold. Uyuni is often below freezing before dawn from May to September. Keep a down jacket in your daypack.
- You lose Potosí. The direct bus is efficient, but you miss one of Bolivia’s most fascinating cities.
Option 2: Break the journey in Potosí
Buses run frequently between Sucre and Potosí throughout the day, and Potosí’s departures to Uyuni continue into the evening. This is the better plan for most travelers:
- Morning: bus from Sucre to Potosí, about 3 hours.
- One or two nights in Potosí: visit the historic centre and acclimatize at over 4,000 m.
- Morning bus to Uyuni: arrive around midday.
- Night in Uyuni: start your tour the next morning, rested.
Connecting With Your Uyuni Tour
Most Uyuni tours, both 1-day and 3-day, leave at around 10:30. Here is how each arrival fits.
| Arrival plan | Arrives Uyuni | Same-day tour? | Verdict |
|---|---|---|---|
| Overnight from Sucre | About 04:00–06:00 | Yes | Works, but expect a cold early wait |
| Early bus from Potosí (07:00) | About 11:00 | No, misses 10:30 departures | Stay the night, tour next day |
| Evening bus from Potosí | About 22:30–01:00 | Next day | Fine if you have a bed booked |
| Midday bus from Potosí, night in Uyuni | Afternoon | Next day | The most comfortable plan |
If you arrive by early evening, you have time to visit your tour agency, check the vehicle and confirm details in person. That is worth doing. For help choosing a tour, see our guide to Salar de Uyuni tours.
Going the Other Way: Uyuni to Potosí or Sucre
Many travelers do the route in reverse after a tour, especially those arriving from Chile.
- To Potosí: buses leave Uyuni throughout the day and into the evening. An evening departure after a 3-day tour gets you to Potosí late at night, so book your accommodation in advance.
- To Sucre: direct overnight buses leave Uyuni around 21:30 to 22:00 and arrive about 05:30 to 06:00. This fits neatly after a 3-day tour that returns in the late afternoon.
Uyuni has no finished terminal building. Bus companies operate from offices clustered around Avenida Cabrera and nearby streets in the town centre.
Private Transfers: When They Make Sense
A private car or 4×4 between Sucre or Potosí and Uyuni costs much more than the bus, but it can make sense for:
- Families with young children, who will find a 4-hour daytime drive much easier than a night bus.
- Groups of four or more, where the per-person cost narrows.
- Photographers, who want to stop on the Altiplano along the way.
- Travelers short on time, who want to leave when they choose rather than at fixed departure times.
Ask your hotel or a reputable agency for a quote, and confirm the vehicle, driver and price in writing.
Practical Tips for This Route
- Pay the terminal fee. Bolivian terminals charge a small usage fee, typically Bs 2 to 2.5, separate from your ticket.
- Keep valuables on you. Passport, phone and cash stay in a bag you hold, not in the overhead rack.
- Get a luggage receipt for anything in the hold.
- Watch for strikes. On 28 September 2026, a national transport strike over diesel prices was strongly observed in Sucre even though La Paz ran normally. Check local news the day before you travel.
- Bring cash. Uyuni’s ATMs are limited and sometimes empty, and park fees on the 3-day route are paid in bolivianos.
