Quick Summary: Sucre, Potosí and Uyuni sit on a single paved road of roughly 360 kilometres, and the right direction depends on where you start. Travellers arriving from the lowlands, from abroad via Santa Cruz, or planning to finish in Chile should go Sucre to Potosí to Uyuni, climbing gradually. Travellers already acclimatised in La Paz often do better reversing the route and finishing in comfortable Sucre. Road legs take about three hours from Sucre to Potosí and three and a half to four hours from Potosí to Uyuni. Book your Uyuni tour and your first night in Uyuni first, then onward transport, and leave buses and Potosí mine tours until you are on the ground.
The Route in One Paragraph
The corridor begins in Sucre, Bolivia’s constitutional capital, at around 2,810 metres. The road climbs through the Pilcomayo valley to Potosí, one of the highest cities in the world at around 4,090 metres, then crosses the Altiplano to Uyuni at around 3,656 metres, on the edge of the world’s largest salt flat. The whole stretch is paved: Route 5 links Sucre and Potosí, and the Potosí–Uyuni section was completed in 2015, cutting what used to be a long, rough journey to a few hours. Both Sucre and Potosí are UNESCO World Heritage cities, so this is one of the most historically rich stretches of road in South America as well as one of the most straightforward to travel.
Which Direction Should You Travel?
This is the decision that shapes the rest of your plan, and it comes down to two factors: altitude and your exit point.
Sucre to Potosí to Uyuni (climbing)
Choose this direction if:
- You are flying into Sucre from Santa Cruz or starting your trip in the lowlands.
- You want to finish your salt-flat tour in Chile at San Pedro de Atacama.
- You are sensitive to altitude and want to spend several nights at a moderate height first.
The CDC Yellow Book notes that two to three nights at moderate altitude before going higher is markedly protective against acute mountain sickness. Sucre does that job well. The step from Sucre to Potosí is still large, at roughly 1,280 metres in one day, so keep your first afternoon in Potosí gentle.
Uyuni to Potosí to Sucre (descending)
Choose this direction if:
- You arrive in Uyuni by overnight bus or flight from La Paz, already acclimatised.
- You want to end your trip in Bolivia’s most comfortable city.
- You plan to fly out of Sucre to Santa Cruz or La Paz.
For travellers who entered Bolivia overland from Peru, this is often the most natural order. Many cross Lake Titicaca on Bolivia Hop, with hotel pickup, a local host and help at the Kasani border, spend a few days in La Paz, then take a separate overnight service south to Uyuni. Bolivia Hop does not run between La Paz and Uyuni or on the Sucre–Potosí–Uyuni corridor, so the southern legs are arranged independently.
A quick decision guide
| Your situation | Best order | Why |
|---|---|---|
| Arriving from Santa Cruz or abroad by air | Sucre → Potosí → Uyuni | Gradual climb from 2,810 m |
| Finishing in San Pedro de Atacama, Chile | Sucre → Potosí → Uyuni | The 3-day tour can end at the Chilean border |
| Coming from La Paz, already acclimatised | Uyuni → Potosí → Sucre | Ends low and relaxed; no backtracking |
| Flying home from Santa Cruz | Uyuni → Potosí → Sucre | Short flight from Sucre to Santa Cruz |
| Altitude-sensitive and short on time | Sucre → Uyuni, Potosí as a daytime stop | Avoids sleeping at 4,090 m |
Travel Times and Transport Options
| Leg | Approx. distance | Typical time | Main options |
|---|---|---|---|
| Sucre → Potosí | About 156 km | About 3 hours (some services quote up to 4) | Frequent daytime buses, shared taxis, private transfer |
| Potosí → Uyuni | About 200 km | About 3.5–4 hours | Daytime buses with limited departures, private transfer |
| Sucre → Uyuni direct | About 360 km | About 8 hours overnight; 7–7.5 hours by private car | Overnight bus, private transfer |
| Uyuni → La Paz | About 550 km | Around 9–12 hours | Overnight tourist-class bed buses, short flights |
Buses
Buses between Sucre and Potosí run throughout the day, with operators listing departures roughly hourly from early morning into the evening. From Potosí to Uyuni, departures are fewer and concentrated in the morning and around midday, so check times the day before. A direct overnight bus from Sucre to Uyuni leaves in the evening and arrives early the next morning.
Public buses on this corridor depart from terminals on the edge of each city. They suit fluent Spanish speakers who are comfortable buying tickets at the counter, navigating busy terminals and arranging their own taxis at each end. For travellers who are not, the time spent reaching terminals, waiting and transferring adds a noticeable amount to what looks like a short journey on paper.
Shared taxis
Shared taxis between Sucre and Potosí are a popular alternative, leaving when full and often completing the journey faster than the bus. Agree the fare before departure, check that the vehicle looks roadworthy, and avoid getting into a car where other passengers appear to know the driver unusually well.
Private transfers
Private transfers offer door-to-door service, a daytime schedule and the option to stop in Potosí for a few hours of sightseeing on the way from Sucre to Uyuni. Operators have listed Sucre–Uyuni private transfers from around US$250 per vehicle. This makes most sense for groups of three or four, families, or travellers with limited time.
What to Book First
Getting the booking order right avoids the most common problem on this route: arriving somewhere only to find the thing you came for is full.
- Your Uyuni tour. This is the most time-sensitive booking, especially in July and August, for private tours, and for 3-day tours ending in Chile. Outside peak months, you can book a day or two before, but shortlist operators in advance. Our Salar de Uyuni tour price guide compares formats and costs.
- Your first night in Uyuni. Accommodation near the tour offices fills quickly in peak season, and a salt hotel on the edge of the flat, if you want one, needs booking ahead.
- Your onward journey from Uyuni. If you are returning to La Paz, book the overnight bus or flight for the evening your tour ends. If you are crossing to Chile, confirm that the border transfer is included in your tour.
- Your accommodation in Sucre and Potosí. Book at least the first night in each city, particularly around festivals and Bolivian holidays.
- Buses between Sucre, Potosí and Uyuni. These can usually be bought the day before at the terminal, or through online ticketing platforms.
- Your Potosí mine tour. Book through your accommodation or a cooperative-linked agency a day ahead, and choose a day after you have adjusted to the altitude. Bolivia Hop’s guide to the Potosí mines covers what to look for in an operator.

Conditions to Factor In for Late 2026
This corridor has been affected by road blockades during past protest episodes, and the current picture calls for flexibility. Bolivia’s Legislative Assembly extended the nationwide state of emergency on 17 September 2026 for a further 90 days, citing the risk of renewed blockades, as reported by Reuters via US News. The government then ended the diesel subsidy on 19 September, with prices rising from 9.80 to 17.95 bolivianos per litre according to The Rio Times. Expect some movement in bus and tour prices, and check the U.S. Embassy’s September 2026 security alert and current road status with the ABC before each leg.
Cash is also worth planning. ATMs in Uyuni can run out, and the tour route has none. The boliviano has been floating since mid-2026, so check the Banco Central de Bolivia rate and withdraw what you need in Sucre or Potosí.
It is essential to schedule travel time to destinations that are conveniently located and arranged in a logical sequence. On this corridor, that means choosing one direction and sticking to it, matching it to your altitude and your exit point, and keeping a buffer night before any flight or border crossing at the end.

FAQ
Is it better to go from Sucre to Uyuni or from Uyuni to Sucre?
It depends on where you start and where you finish. If you are arriving from the lowlands or abroad, or if you want to end your salt-flat tour in Chile, go from Sucre to Uyuni so that you climb gradually and finish at the tour’s starting point. If you are coming from La Paz and are already acclimatised, going from Uyuni to Sucre is usually better, because you descend, avoid backtracking and end your trip in the most comfortable city on the route. Neither direction is wrong; the mistake is choosing one that forces you to retrace the same road.
Can I travel from Sucre to Uyuni in one day and still see Potosí?
Yes, with a private transfer or careful bus planning. A private car can stop in Potosí for a few hours, allowing you to visit the Casa de la Moneda and the historic centre before continuing to Uyuni the same day. By bus, you would need an early departure from Sucre, a short stop in Potosí and one of the limited afternoon connections to Uyuni, which leaves little margin. Most travellers find one night in Potosí more enjoyable and better for acclimatisation.
Do I need to book buses in advance on this route?
Usually not. Buses between Sucre and Potosí run frequently, and tickets can typically be bought at the terminal on the day or the day before. Potosí to Uyuni has fewer departures, so buying a day ahead is sensible, particularly in July, August and during holidays. Overnight buses from Uyuni to La Paz fill faster in peak season, so book those in advance if your tour ends on a specific day and you need to leave that evening.
Is the road between Potosí and Uyuni safe?
The road is fully paved and in generally good condition, which has made the journey much easier than it was before 2015. As with any long road in Bolivia, the main risks come from driving practices, weather and fatigue rather than the road surface itself. Choose established operators, travel by day where possible, keep valuables with you rather than in overhead racks, and check for road disruptions before departure given the political situation in late 2026.
What if a blockade closes the road between the cities?
Do not attempt to pass a blockade on foot or by car. Stay where you are, contact your accommodation and tour operator, and follow local news for updates. Blockades in Bolivia can last from a few hours to several days. If you have a fixed flight or border crossing at the end of the route, a buffer night gives you room to wait. Flights between Sucre, La Paz and Santa Cruz have generally continued operating during past road disruptions and may offer a way around a closure.
Limitations
Bus schedules, shared-taxi fares and private transfer prices on this corridor were drawn from operator listings and recent guides rather than confirmed directly, and fuel price changes in September 2026 may already have affected them, so confirm times and fares at the terminal or with your accommodation the day before each leg. Road conditions and the risk of blockades can change quickly under the extended state of emergency; mitigate this by building a buffer night before any flight or border crossing and checking official sources before departure.
