Cerro Rico, the "rich mountain," towers over the city of Potosi at 4,786 meters elevation. Discovered by the Spanish in 1545, this mountain was the greatest silver mine in history and sustained the wealth of the Spanish crown for two centuries. Still mined today, it has been listed as a UNESCO World Heritage Site in Danger since 2014 due to progressive collapse of its summit.

Why Visit Cerro Rico

A tour of the active Cerro Rico mines is no ordinary tourist attraction. It offers an immersion into the daily lives of the mineros who continue extraction under extremely difficult conditions, in galleries carved since the 16th century. It is also an opportunity to understand a unique religious syncretism in Bolivie, where Catholic worship coexists with veneration of the Tío, a protective deity of the underground.

Three reasons primarily motivate the visit:

• Explore South American colonial history at its founding site
• Meet the miners and observe their rituals
• Enjoy panoramic views of the Kari Kari mountain range and Nuevo Mundo volcano

History of Cerro Rico

Before the conquest, Inca peoples considered Cerro Rico a huaca, a sacred mountain. During periods of unrest or transition, human sacrifices were celebrated at its summit in honor of Huiracocha and Pachamama.

Mining history began in January 1545, when the indigenous Diego Huallpa discovered an outcropping silver vein. He initially exploited the site for his own account before informing his friend Huanca, who served majordomo Diego de Villarroel. Under the command of Lorenzo de Estupiñan, the conquerors took control of the mine. News of the discovery brought a considerable influx of people from across the Viceroyalty of Peru, and the city of Potosi was founded at the mountain's base in 1546.

In the 16th and 17th centuries, silver from Cerro Rico financed much of the Spanish empire. On-site, religious life transformed through a blend of indigenous cultures and Catholicism: the Virgin Mary was depicted with Cerro as her mantle, merging with Pachamama. It was also during this period that the Tío cult was born in the depths of the galleries—a protective figure that miners still honor today. Mining continued uninterrupted, and an open-pit mine was opened on the mountain's slopes in 2008.

What to See and Do at Cerro Rico

Inside the Galleries

The mountain is pierced by approximately 5,000 galleries serving nearly 200 mines, some descending more than 450 meters deep. The guided tour requires full equipment: boots, helmet with headlamp, and respiratory protection against dust and fumes. The route alternates between traversing rock blocks and descending through narrow tunnels. Good physical fitness and absence of claustrophobia are essential.

The Tío Cult

At the heart of the mine stands a statue of the Tío, to which miners leave offerings. Visitors are invited to participate by bringing American cigarettes or coca leaves, purchased at the miners' market before the tour. This brief but moving moment illuminates the spiritual dimension of underground work.

The Miners' Lives

Sirens sound the wake-up call at 6 a.m. Miners venture into the socavones for approximately 10-hour shifts, six days a week. The profession passes from generation to generation despite the risks (cave-ins, silicosis, dynamite explosions). Earnings remain modest: the luckiest can reach around €150 per month, often reduced by the cost of tools and explosives. Many nonetheless prefer mine work to labor in the coca plantations of the Chapare valleys.

The Panoramas

From the heights of Cerro Rico, views extend over the Kari Kari mountain range to the south and the Nuevo Mundo volcano to the east.

Practical Information

• Duration: plan for approximately half a day, including transfer from Potosi
• Rates: moderate for a group guided tour; budget extra for Tío offerings
• Equipment: provided by agencies (suit, boots, helmet)
• Acclimatization: allow at least 1 to 2 days at altitude before the visit
• Not recommended for those with claustrophobia, asthma, or heart conditions

When to Visit Cerro Rico

High altitude means cool temperatures year-round. The dry season, April to October, remains most favorable: sunny days and easier access to the mountain's surroundings. During the southern winter (June-July), nights can drop below freezing, while summer days (December-February) are milder but punctuated by showers. Prioritize morning visits, when activity in the galleries is most active.

How to Reach Cerro Rico

Cerro Rico is located approximately 10 km from Potosi, roughly thirty minutes by car via Av. Poleoducto, Route 1, or Route 5. Most visitors arrange a visit through a local agency that includes transfer from the city center.

To reach Potosi:

• From Sucre (150 km): approximately 3 hours by bus
• From La Paz (500 km): 8 to 10 hours by overnight bus
• From Oruro (320 km): approximately 6 hours of driving

Potosi's Capitán Nicolás Rojas airport remains minimally served; domestic flights typically arrive at Sucre.

Around Cerro Rico

The historic center of Potosi, at 4,070 meters elevation, is one of the world's highest cities and is listed as a UNESCO World Heritage Site. Among the sites to explore:

• Casa de la Moneda: former mint building that traces mining and colonial history
• San Francisco Church: portal carved from rock
• Torre de la Compania: 18th-century bell tower
• San Lorenzo Church: emblematic facade of mestizo art
• The traditional market, where you can taste an almuerzo

To extend your discovery of mineral and Andean Bolivie, you can also visit the Valley of the Moon near La Paz or the Lauca River.
