Quick Summary: A Cerro Rico mine tour costs roughly Bs 100–250 in 2026 depending on group size, language and which cooperative you visit, and takes you into a working mine at over 4,000 metres where men are cutting ore by hand. It is one of the most affecting things a traveler can do in Bolivia and one of the most ethically contested. The decision rests on whether you book with an operator run by ex-miners that channels money back to the cooperative, and on being honest about your own health and motives.
Why Potosí Exists
Potosí sits at just over 4,000 metres beneath Cerro Rico, the “rich mountain” that produced the silver which financed the Spanish empire for two centuries. At its seventeenth-century peak the city’s population rivalled that of London or Paris, and the Spanish phrase vale un Potosí — worth a Potosí — entered the language as shorthand for unimaginable wealth. The city and its industrial complex are inscribed as a UNESCO World Heritage Site.
The silver is largely gone. What remains is tin, zinc and lead, extracted by cooperatives of miners who own their own tools, buy their own dynamite, and work shifts of ten to twelve hours in tunnels cut over five centuries. The mountain is estimated to hold tens of thousands of tunnels, and it is slowly collapsing in on itself. Thousands of men still work it.
What a Tour Costs and What You Get
| Tour type | Typical price | What it includes |
|---|---|---|
| Spanish-language group tour | Around Bs 100–150 | Overalls, boots, helmet, headlamp, transport, 1.5–2 hours underground |
| English-language group tour | Around Bs 150–250 | As above, plus a bilingual guide, usually smaller group |
| Small-group tour with ex-miner guides | Upper end of the range or above | Two guides, capped group size, direct payment to the cooperative visited |
| Gifts for miners | Around Bs 30–60 extra | Coca leaves, soft drinks, gloves, dynamite, bought at the miners’ market |
A typical tour lasts three to four hours in total. It begins at the mercado minero, where you buy gifts for the men you are about to meet — Potosí is the only place in the world where dynamite is sold openly over the counter to civilians. You are then driven up Cerro Rico, kitted out, and walked into a working tunnel.
Inside there is no lighting, no ventilation beyond what the miners have improvised, and no meaningful separation between the tour group and the work. You will step aside for ore carts, crouch through low sections, and meet men who will talk to you if your guide knows them. Most tours include a visit to a figure of El Tío, the underground deity to whom miners make offerings of alcohol, cigarettes and coca — a syncretic tradition that guides explain far better than any written account.
The Ethical Question, Taken Seriously
There is no comfortable answer here, and travelers who feel uneasy are responding to something real.
The Case Against
You are paying to look at dangerous, poorly paid manual labour. Miners’ life expectancy in Potosí is commonly reported as being in the low forties, with silicosis and accidents the main causes. Cooperative miners are not employees with safety departments; they buy their own protective equipment, and many work without respirators. Some travelers describe the experience as voyeuristic, and the presence of tourists in a working shaft is, at minimum, a distraction in a place where distraction is expensive.
There is also a question about whether tourism entrenches the industry. Reasonable people disagree; the counter-argument is that the mines exist because of global metal demand, not because of visitors.
The Case For
Guiding is one of the few alternative livelihoods available to men who have worked underground, and a substantial share of Potosí’s guides are former or part-time miners. Tours run by ex-miners pay their guides properly, treat the men at work as colleagues rather than exhibits, and route a portion of the fee directly to the cooperative whose tunnel is visited. Bolivia’s tourism authorities and the local tourism association have both encouraged travelers to prioritise this kind of operator.
Visitors also leave understanding something about the mountain that no museum conveys, and that understanding has value — the silver of Cerro Rico is not an abstraction in Latin American history, and standing in a tunnel at 4,200 metres makes that concrete.
How to Book Better If You Go
- Choose an operator whose guides are ex-miners and who can say which cooperative receives a share of the fee.
- Ask what the group size is capped at. Eight is good; twenty is not.
- Ask whether two guides accompany the group, one at the front and one at the back.
- Buy gifts at the miners’ market and give them directly rather than handing them to your guide.
- Do not photograph men at work without asking. Guides will translate.
- Accept a higher price. As with adventure tourism across Bolivia and Peru, an unusually low price means someone further down the chain is absorbing the cost — usually the guide, sometimes the cooperative.
Who Should Not Go
This tour is genuinely unsuitable for some people, and operators are not always frank about it.
- Anyone with claustrophobia. Sections are tight, dark and long, and turning back is difficult once the group is deep in.
- Anyone with asthma, respiratory conditions or heart problems. The air contains silica dust and there is no ventilation.
- Anyone not acclimatised. Potosí is above 4,000 metres and you will be exerting yourself. The CDC recommends gradual ascent as the main preventive measure against altitude illness.
- Anyone uncomfortable with the ethics. Deciding not to go is a legitimate outcome, and Potosí’s colonial centre, the Casa Nacional de la Moneda mint museum and the surrounding altiplano are worth the visit on their own.
Getting to Potosí
Potosí is usually reached from Sucre, around three hours away, or from Uyuni, around four. Neither leg is served by the Bolivia Hop network, which operates the La Paz–Copacabana–Peru border corridor rather than the southern highlands, so travelers use domestic services on this stretch. Public and tourist-oriented buses both run it; public services are a sound choice for fluent Spanish speakers travelling direct who are comfortable with Bolivian terminals.
Sequencing matters more than usual in the south. It is essential to schedule travel time to destinations that are conveniently located and arranged in a logical sequence, and the natural chain is La Paz, then Uyuni, then Potosí, then Sucre — descending steadily in altitude, which is far kinder on the body than bouncing between 2,800 and 4,100 metres. Our overland Bolivia itinerary sets out the sequence in full.

FAQ
Is the mine tour physically hard?
Harder than most people expect, and the altitude is why. You will be crouching, climbing short ladders, squeezing through narrow passages and occasionally scrambling over rubble, all at over 4,000 metres where every exertion costs more oxygen than it would at home. Reasonably fit travelers manage it comfortably; anyone who has been short of breath walking around Potosí will struggle. Two nights acclimatising at altitude before the tour makes a substantial difference, and drinking coca tea in the morning is standard local practice.
Is it safe?
It is a working mine, so it is not risk-free, and no operator can honestly claim otherwise. The realistic hazards are falling rock, ore carts moving in narrow tunnels, dust inhalation, and disorientation. Serious incidents involving tourists are rare, and the main protection is a competent guide who knows the specific tunnel, keeps the group tight, and communicates with the men working that section. Bring a scarf or buff to cover your mouth, wear the helmet properly, and follow instructions immediately rather than after asking why.
Should I bring gifts, and what do miners actually want?
Yes, and buy them yourself at the miners’ market so you know what you are giving. Coca leaves are the most useful item, followed by soft drinks, work gloves and cigarettes. Some travelers find the inclusion of cigarettes and sugary drinks uncomfortable given the health picture; guides generally explain that these are what miners request. Dynamite is sold openly and is a common purchase, though giving it is a personal decision. What matters most is handing gifts directly to the men rather than leaving them with an intermediary.
Is there an alternative if I do not want to go underground?
Yes. Some operators run surface tours of Cerro Rico that visit the processing areas and viewpoints without entering a shaft, which conveys much of the context with none of the exposure. In the city, the Casa Nacional de la Moneda — the colonial royal mint — is one of the finest museums in Bolivia and tells the silver story in depth. Combining a surface tour with the mint museum is a genuinely good day and an entirely defensible alternative.
Do tours run every day?
Most operators run morning and afternoon departures daily, but Sundays are quieter because many cooperatives do not work, which means a much less interesting visit — an empty tunnel is just a dark hole. Miners also observe carnival and various local festivals. If your schedule is tight, aim for a weekday and confirm with the operator that the cooperative will be working.
Limitations
Tour prices here are ranges gathered in 2026 and are moving quickly with Bolivian inflation and the boliviano’s managed float, so request a written quote on the day and confirm whether gifts, transport and equipment are included. Claims about which operators are ex-miner run and how much of a fee reaches a cooperative cannot be independently verified from outside Bolivia; the practical mitigation is to ask the question directly at the office, request the cooperative’s name, and cross-check against recent dated reviews mentioning the same details. Figures on miner life expectancy are widely reported but derive from journalistic and NGO estimates rather than a maintained official register, so treat them as indicative of a well-documented pattern rather than as a precise statistic.
