The Uyuni – Potosí route brings together two of Bolivia’s most powerful faces in one journey. On one side, there is the endless white landscape of the Salar de Uyuni, where the ground seems to merge with the sky. On the other, there is Potosí, a city shaped by the shadow of Cerro Rico and centuries of mining history. This route is not only about beautiful photos; it is also a way to understand nature, colonial history, mining, altitude and the Andean landscape.
Many travelers arrive in Uyuni with one image in mind: perspective photos on the white salt flat or the famous mirror effect during the rainy season. And yes, Salar de Uyuni is truly breathtaking. But the region is much more than the salt flat. The Train Cemetery, Isla Incahuasi, Colchani, high-altitude lagoons, the historic center of Potosí, the National Mint and the history of Cerro Rico make this route much deeper.

Uyuni and Potosí overview
Uyuni is a small town in southwestern Bolivia, in the department of Potosí. At first glance, it may look simple and functional, but it is the main gateway to the Salar de Uyuni, the largest salt flat in the world.
Potosí has a completely different atmosphere. Located at almost 4,000 meters above sea level, it is one of the highest cities in the world. Its identity is marked by Cerro Rico and centuries of silver mining.
Visiting both places on the same route helps you understand Bolivia in a deeper way. Uyuni shows the country’s natural grandeur; Potosí shows the weight of its history.
Why Salar de Uyuni is so special
Salar de Uyuni covers more than 10,000 square kilometers and is considered the largest salt flat on Earth. It was formed from prehistoric lakes that dried out, leaving behind a vast white salt surface.
In the dry season, the salt surface reveals hexagonal patterns and an endless white horizon. In the rainy season, if enough water covers the surface, the salt flat becomes a giant mirror reflecting the sky.
Salar de Uyuni is also important because of its lithium reserves. It is not only a natural wonder, but also a key area for Bolivia’s economic future.
Potosí and the shadow of Cerro Rico
The history of Potosí is inseparable from Cerro Rico. From the 16th century onward, this mountain became one of the main sources of silver for the Spanish Empire.
The wealth extracted from Cerro Rico fed the colonial economy, but the human cost was enormous. Potosí cannot be understood without talking about exploitation, forced labor, mining and inequality.
The historic city of Potosí is listed as a UNESCO World Heritage Site. You can read more on the UNESCO page for the City of Potosí.
How to get to Uyuni
From La Paz
The most common way to travel from La Paz to Uyuni is by night bus. The journey is long and at high altitude, so it is worth choosing a comfortable and reliable company.
From Sucre or Potosí
A very logical route within Bolivia is Sucre – Potosí – Uyuni. This combination connects historic cities with the country’s most famous natural landscape.
From Chile
You can also arrive from San Pedro de Atacama on multi-day tours that cross high-altitude lagoons, deserts and volcanic landscapes. It is spectacular, but physically demanding.
How to get to Potosí
Potosí has road connections with Sucre, Uyuni, Oruro and La Paz. The Sucre – Potosí route is one of the most common connections in southern Bolivia.
When you arrive in Potosí, remember the altitude. Take the first day slowly, walk short distances and leave the more demanding visits for after some acclimatization.
How to plan the Uyuni – Potosí route
The route can be done in either direction. If you are coming from northern Bolivia, a good sequence is La Paz – Sucre – Potosí – Uyuni. If you enter from Chile, San Pedro de Atacama – Uyuni – Potosí – Sucre may make more sense.
Ideally, do not rush. Potosí needs time for its history to sink in, and Uyuni needs at least one full day to experience the salt flat properly.
How to choose a Salar de Uyuni tour
In Uyuni, you will find 1-day, 2-day and 3-day tours. One-day tours usually include the Train Cemetery, Colchani, the salt flat, Isla Incahuasi and sunset. Three-day tours go farther, reaching high-altitude lagoons, deserts, geysers, hot springs and areas near the Chilean border.
Do not choose only by price. Ask about the vehicle condition, seat belts, driver experience, meals, accommodation, included entrance fees and route changes during the rainy season.
Things to see in Uyuni
Salar de Uyuni
This is the heart of the route. In the dry season, the salt patterns and endless white surface stand out. In the rainy season, the mirror effect can make the sky and ground blend together.
Isla Incahuasi
Isla Incahuasi is a rocky island covered with giant cacti in the middle of the salt flat. From its trails, you can better understand the scale of Salar de Uyuni.
Train Cemetery
The Train Cemetery shows Uyuni’s railway and industrial past. Rusted locomotives, old wagons and desert wind create a melancholic and photogenic atmosphere.

Colchani
Colchani is a small settlement near the salt flat. It offers a brief look at salt production and local crafts.
Things to see in Potosí
Cerro Rico
Cerro Rico is the symbol of Potosí. It is not just a mountain; it is the historical, economic and human center that shaped the destiny of the city.
National Mint of Bolivia
The National Mint is one of the most important visits in Potosí. It helps explain silver, colonial economy and the city’s role in world history.
Historic center
The historic center of Potosí can be explored on foot, but slowly. At this altitude, even short walks can feel demanding.

Cerro Rico and mine tours
Mine tours in Cerro Rico are a sensitive experience. They can help visitors understand real working conditions, but they are not suitable for everyone. There are narrow spaces, dust, darkness, altitude and a very hard labor reality.
Before joining a mine tour, ask yourself whether you have claustrophobia, respiratory issues or difficulty with altitude. If you are unsure, the National Mint and historic center are strong alternatives.
Where to stay
In Uyuni, accommodation is usually a practical stop before or after the tour. The most important things are cleanliness, safety, hot water and proximity to agencies or transport.
In Potosí, staying near the historic center is practical, but check heating, hot water and whether the hotel has many stairs. At this altitude, stairs feel harder than usual.
Transport, roads and self-driving
There are bus connections between Uyuni, Potosí and Sucre. In Bolivia, travel times can change because of weather, roads or delays, so avoid planning very tight connections.
Driving into the salt flat with your own vehicle can be risky because of salt, water, mud, navigation issues and limited phone signal. Even if you have a car, local information or a guided tour is safer for entering the salar.
Budget and money
Tour prices in Uyuni vary a lot. The cheapest option is not always the best. Safety, vehicle condition, driver experience, food and accommodation matter.
Carry cash in Bolivianos for entrance fees, toilets, tips, small expenses and local purchases. Cards are not accepted everywhere.
Altitude, health and safety
Uyuni is around 3,600 meters above sea level, while Potosí is close to 4,000 meters. Altitude sickness can cause headaches, tiredness, loss of appetite, nausea or poor sleep.
Walk slowly, drink water, avoid alcohol at first and do not overfill your first day with demanding activities. On long tours, prepare for strong sun during the day and serious cold at night.
When to go
The dry season, from May to October, usually offers clearer skies and visible salt patterns. It is ideal for perspective photos.
The rainy season, from December to March, can create the famous mirror effect. It is not guaranteed, but when it appears, it is one of Bolivia’s most magical sights.
How many days to spend in Uyuni and Potosí
For a fast route, 2 days can be enough: one day in Uyuni and one day in Potosí. For a more complete experience, 4 or 5 days are much better.
If you want to add Sucre, plan 6 or 7 days for the Sucre – Potosí – Uyuni route.
Photography and gear tips
Salar de Uyuni is one of the most creative places in the world for photography. Bring small objects for perspective photos, extra batteries, sunglasses, sunscreen and something to clean salt from your camera, shoes and backpack.
During the rainy season, protect your phone or camera from water. For sunset or night photography, a tripod and warm clothing can be very useful.

Final notes
The Uyuni – Potosí route shows one of Bolivia’s strongest contrasts. Uyuni offers endless white landscapes, sky reflections and almost unreal nature. Potosí carries the weight of history, mining and the colonial past.
