Potosí sits at around 4,090 metres above sea level in southern Bolivia, making it one of the highest cities in the world. The altitude is the first thing you feel. The second, once you start looking around, is the weight of what this place once was: a city that in the 17th century held a population that rivalled the largest cities in Europe, built on the back of a mountain that produced more silver than anywhere else on Earth.
What Potosí was and what it is now
In the 16th and 17th centuries, Potosí was among the most important cities in the Western Hemisphere. The Cerro Rico, Rich Mountain, contained silver deposits so vast that Spanish colonial administrators built an entire economic system around extracting them. The Spanish phrase “vale un Potosí” (worth a Potosí) entered the language to mean something of incalculable value. At its peak in the early 17th century, the city had a population estimated at around 200,000 people, sustained by forced indigenous labour under the mita system and by enslaved African workers.
That history is physically present in Potosí in a way that’s hard to avoid. The colonial churches, the Casa de la Moneda (royal mint), the mansions of the silver traders: all of it was built on extraction that cost the lives of a vast number of Indigenous and enslaved workers over three centuries. Cerro Rico is still being mined today, though the silver deposits are largely exhausted and miners now work primarily for tin, zinc, and other minerals.
Potosí today is a city of around 230,000 people navigating a post-mining economy. The historic centre is genuinely impressive and well-preserved. The everyday city beyond the tourist zone is poor by Bolivian standards. Understanding the gap between the colonial grandeur and the present condition of the city is part of what makes Potosí a significant place to visit.
Getting to Potosí
From La Paz: The most common approach. Buses run overnight from La Paz (the journey takes around 9 to 11 hours) and are the standard budget option. Daytime buses run too, with similar times. The road passes through stunning altiplano scenery. Several companies operate the route; quality varies. Book ahead for overnight services.
From Sucre: Bolivia’s constitutional capital is around 3 hours by bus or taxi from Potosí. The two cities are often paired on itineraries; Sucre at around 2,800m offers a lower-altitude rest before or after Potosí.
From Uyuni: Buses connect Potosí and Uyuni in around 3 to 4 hours. This is the most natural route for travellers doing the salt flat–Potosí–La Paz sequence. Road conditions vary; the journey can be longer in the wet season.
Potosí has a small airport with limited service. Most international travellers arrive by land.
Cerro Rico and the mine tours
The Cerro Rico mine is the defining visit in Potosí. The mountain is visibly pocked with extraction; thousands of mine entrances cover the slopes, and the mountain has subsided noticeably at the summit, a visible consequence of centuries of excavation.
Tours of active mines have operated since the 1980s. They take visitors into the tunnels alongside working miners; the mines are genuinely active workplaces, not heritage sites. The experience involves walking through narrow passages, crouching in low sections, and seeing the conditions under which hundreds of miners still work daily.
What to expect physically: The tour requires entering tight, low tunnels in high heat and dust. At 4,000m plus (some tunnels go to higher elevations within the mountain), the physical exertion is significant. The air quality is poor. Tours typically last 2 to 4 hours.
The ethical dimension: Mine tours are controversial in a way that most travel articles don’t engage with honestly. The tours generate income for mining cooperatives and individual miners who receive tips and gifts (dynamite sticks, coca leaves, and rubbing alcohol; specific items that the miners use and that visitors bring as gifts). They provide visibility into working conditions that might otherwise remain invisible. The counterargument is that the spectacle of poverty and dangerous labour as a tourist attraction raises real questions.
There is no clean answer here. Visitors who choose to do the tour should go with a reputable cooperative-affiliated agency rather than a budget operator, take the conditions seriously rather than treating it as an adventure activity, and tip generously. Visitors who choose not to go, and there are good reasons not to, can still access Cerro Rico’s history through the Casa de la Moneda and Potosí’s other historical sites.
Children under 14 are generally not permitted on mine tours. People with respiratory conditions, claustrophobia, or altitude-related issues should not go.
The historic centre: colonial architecture and Casa de la Moneda
Potosí’s historic centre was designated a UNESCO World Heritage Site in 1987. The scale of colonial construction here is a direct measure of how much wealth passed through this city. The churches alone (over 30 colonial-era churches, many with ornate facades) represent a concentration of religious architecture that’s unusual even by Bolivian standards.
Casa de la Moneda (Royal Mint): The most important building in the city. Built in the 18th century to replace an earlier mint, it processed enormous quantities of silver coin that circulated across the Spanish empire and beyond. The museum inside covers the coin production process, colonial history, and the social history of Potosí. Allow 2 to 3 hours. Guided tours run regularly and are recommended for context.
The Cathedral and Plaza 10 de Noviembre: The central plaza is surrounded by the cathedral and colonial-era civic buildings. The cathedral’s current neoclassical building dates from the early 19th century, though the church has older origins. The plaza is lively in the evenings and a useful orientation point.
Church of San Lorenzo: The most photographed facade in Potosí, an ornate baroque portal in mestizo style, blending Spanish and indigenous motifs. The surrounding street of Calle Quijarro gives a sense of the colonial street scale.
The Potosí Market: The main market, centred on Mercado Central, is a working Bolivian market rather than a tourist market. Good for food, context, and the kind of activity that shows what a living city actually looks like away from the historic monuments.
Altitude in Potosí: higher than almost anywhere
At 4,090m, Potosí is higher than Puno (3,830m), higher than La Paz city centre (3,650m), and higher than Cusco (3,400m). It is one of the highest cities of significant size anywhere in the world.
Altitude sickness is a serious concern. If you’re coming from lower elevations, expect headaches, fatigue, and shortness of breath. Even travellers who have already acclimatized in La Paz may feel the additional 400 to 500 metres. The Cerro Rico mine, which takes visitors to higher elevations within the mountain, should not be attempted until you have spent at least one full day at Potosí’s altitude.
Standard altitude precautions apply: move slowly for the first day, hydrate well, avoid alcohol initially, and don’t push through symptoms that are getting worse rather than better. Coca tea is ubiquitous in Potosí and widely used by locals and visitors alike for mild altitude effects.
Where to eat and sleep
Potosí has a solid range of accommodation spread around the historic centre. Budget guesthouses and mid-range hotels are both plentiful. Heating is important; nights at 4,090m are cold year-round, and even in the warmer months (December–February), temperatures drop sharply after dark.
The food in Potosí follows Bolivian highland cooking: hearty, starch-based, and built for altitude. Local specialties include puchero potosino (a meat and vegetable stew) and llajwa (a fresh salsa of tomatoes and locoto pepper that appears on almost every table). The central market area has cheap, filling lunch menus. Better restaurants around the Plaza 10 de Noviembre and Calle Matos offer more varied menus for dinner.
El Mesón and La Casona (in the historic centre) are frequently recommended for both food quality and setting.
How long to spend in Potosí
Two nights is the practical minimum. That gives you one day for the Casa de la Moneda, a walk through the historic centre, and the main colonial churches, and one day for Cerro Rico if you choose to do the mine tour.
Three nights is comfortable and allows you to explore the city more slowly, visit the market area at leisure, and have time to recover from any altitude adjustment.
More than three nights is unusual unless you have a specific historical or research interest in the city.
Potosí and the Uyuni connection
Potosí and Uyuni are commonly combined. The bus journey between them takes around 3 to 4 hours on a route through altiplano landscape. Most travellers heading to the Uyuni salt flats include Potosí as either a precursor stop (La Paz → Potosí → Uyuni) or a return stop (Uyuni → Potosí → Sucre or La Paz).
Potosí is at higher altitude than Uyuni (3,656m), so some travellers acclimatize in Uyuni before going up to Potosí. Others come to Potosí from La Paz and descend to Uyuni afterward. Either sequence works; the altitude in Potosí is the variable to plan around.
Frequently asked questions
How high is Potosí and how does the altitude affect you? Potosí sits at around 4,090m, higher than most other major cities travellers encounter in South America, including Cusco and La Paz city centre. Expect real altitude effects: headache, fatigue, and laboured breathing are common in the first 24 to 48 hours. Acclimatize before attempting the mine tour.
Is the Cerro Rico mine tour ethical? The answer isn’t simple. Tours support miners directly through tips and purchases. The alternative argument is that active working conditions shouldn’t be a tourist attraction. If you go, use a cooperative-affiliated agency, take the experience seriously, and tip well. If you don’t go, the Casa de la Moneda covers the history thoroughly.
What is Casa de la Moneda? The Royal Mint of Potosí, one of the most important colonial buildings in South America. Built in the 18th century to produce silver coins from Cerro Rico’s output. The museum covers coin production, colonial history, and the economic history of the Spanish empire’s silver system. Allow 2 to 3 hours.
Is Potosí safe for tourists? Generally yes in the historic centre and main tourist areas. The usual precautions apply: don’t display expensive electronics, be aware of your surroundings, and use taxis arranged through your hotel at night. Petty theft exists; violent crime targeting tourists is uncommon.
How do I get to Potosí from La Paz? Overnight buses are the standard option, journey time around 9 to 11 hours. Several companies operate the route with varying quality. Book ahead for overnight services. Daytime buses exist with similar times.
How long should I spend in Potosí? Two nights is the minimum for the main sights. Three nights is more comfortable, particularly if altitude adjustment eats into your first day’s energy.
What is the best way to get from Potosí to Uyuni? Bus is the standard option, around 3 to 4 hours on a route through altiplano. Multiple companies operate the route daily. The road can be rough in the wet season (November–April) and longer in bad conditions. Shared taxis cover the route faster but cost more.
What are the must-see buildings in Potosí’s historic centre? Casa de la Moneda, the Cathedral on the main plaza, the Church of San Lorenzo (for the baroque facade), and the Church of San Francisco (oldest church in the city, with rooftop access) are the main architectural anchors. The surrounding colonial streets reward wandering without a specific agenda.
