The Best-Kept Secret Under Cali's Asphalt
If you walk through downtown Cali, right where Carrera 4 meets Calle 11, the ground beneath your feet hides more history than you imagine. Below the buses, street vendors, and city noise, there exists a network of tunnels, passages, and vaults dating back to the colonial era, the republic, and even the gold rush. It is not fiction or an urban legend: it is the underground Cali, a heritage few know about and that is just beginning to be explored. As of June 2026, some sections are still closed to the public, but others can already be visited with local guides who know every brick. This article is a guide for you to delve into that hidden world, with verifiable data, real names, and useful recommendations.
Downtown Tunnels: From Canal del Pueblo to Pasaje del Comercio
The historic center of Cali was not only the political and religious heart of the city but also a strategic point for commerce and defense. During the 18th and 19th centuries, tunnels were built connecting key buildings, such as San Pedro Cathedral, the National Palace, and some elite homes. Today, many of these passages are walled up or converted into warehouses, but some survive and are accessible.

Canal del Pueblo
Located under Carrera 4 between Calles 11 and 12, Canal del Pueblo is not a tunnel in the strict sense, but an old sewage canal dating from the early 20th century. It was built to drain downtown floods, but its brick vaulted design and its extension of almost 500 meters make it an impressive underground passage. Today, the Mayor's Office of Cali has enabled sporadic tours (it is recommended to check dates with the Secretary of Culture) that allow you to walk inside. Bring rubber boots and a flashlight: the floor is muddy and the temperature hovers around 18°C.
Pasaje del Comercio
This pedestrian passage, connecting Carrera 4 with Carrera 5 at the height of Calle 12, is one of the few commercial tunnels still in operation. Originally it was a covered alley that linked Plaza de Cayzedo with the old market. During the 1920s, it became a center for trading fabrics and jewelry. The exposed brick vaults and semicircular arches are still preserved, although many shops have been replaced by fast-food outlets. It is not a guided tour, but you can explore it freely from 8am to 7pm. Look at the marble plaques on the walls: some mark the boundaries of old properties.
The Gobernación Tunnel
Under the building of the Gobernación del Valle, at Carrera 4 with Calle 9, there is a tunnel that connected to the old Cali prison. It was used to transfer prisoners without being seen from the street. Today it is closed to the public, but its entrance can be seen from the building's basement during guided tours organized by the Municipal Secretary of Culture. Ask at the Gobernación reception for tour times, which are usually on Thursday mornings.
Vaults of San Pedro Cathedral: Colonial Refuges
San Pedro Cathedral, on Plaza de Cayzedo, is not only the oldest temple in Cali (its construction began in 1772), but it also houses a system of underground crypts and vaults that served as a refuge during earthquakes and, according to some historians, as a hiding place for valuables during the war of independence. The vaults are made of brick and lime, with semicircular arches that support the entire weight of the church. Access is only possible with authorization from the parish priest, and visits are limited to small groups. Contact the parish at least one week in advance. The tour lasts about 30 minutes and costs around $15,000 COP per person (reference price as of June 2026). Do not expect artificial lighting: bring your own flashlight.
Hidden Passages of San Antonio: Legends of Smuggling and Resistance
The San Antonio neighborhood, famous for its hill and colonial church, hides a network of underground passages that connected old houses with the Cali River. During the 19th century, these tunnels were used to move contraband goods from the port of Buenaventura to downtown shops, avoiding customs taxes. They are also said to have served as escape routes during civil wars.
The Passage of Casa de la Memoria
At Calle 4 with Carrera 6, Casa de la Memoria (a cultural center documenting the history of the armed conflict in Cali) has a basement that connects to a tunnel leading to the river. It is not permanently open to the public, but tours are held during the Cali Fair or special events. Ask at the Casa de la Memoria reception, which is open Tuesday to Saturday from 9am to 5pm. Entry is free, but the tunnel requires prior reservation.
The Tunnel of Loma de la Cruz
Going up Calle 5 towards Loma de la Cruz, there is an old mansion known as Casa de los Virreyes (today a restaurant called "El Virrey"). Its owner, Don Carlos, says the basement has an entrance to a tunnel that goes down to the banks of the Cali River. Although it cannot be visited, Don Carlos sometimes shows the tunnel's mouth to diners who ask. It is worth going for lunch (dishes from $25,000 COP) and asking him to tell you the story.
How to Access: Permits, Local Guides, and Precautions
Accessing underground Cali is not as simple as buying a ticket at a box office. Most tunnels are on private property or under public buildings and require special permits. Here are the keys:
- Local guides: The best option is to contact the Cali Tourism Guides Association (AGT Cali). They offer underground tours that include Canal del Pueblo and the Cathedral vaults. Prices range from $40,000 to $60,000 COP per person, depending on the group. It is recommended to book at least three days in advance.
- Municipal permits: To visit the Gobernación tunnel or Canal del Pueblo, you must request authorization from the Cali Secretary of Culture (Carrera 5 # 11-25, second floor). The process is free but can take up to a week.
- Precautions: Wear closed-toe shoes with non-slip soles, clothes you can get dirty, a flashlight (preferably a headlamp), water, and a reflective vest if entering Canal del Pueblo. Some tunnels have poor ventilation; if you suffer from claustrophobia, assess if it is for you. Do not go alone: always go with a guide or in a group.
- Hours: Most visits take place between 9am and 2pm, Tuesday to Saturday. Sundays and holidays are usually closed.
A Journey to the Cali That Doesn't Appear on Maps
Underground Cali is not a theme park or a massive tourist attraction. It is a journey into the past that requires patience, curiosity, and respect for heritage. Every brick, every arch, and every tunnel tells the story of a city that grew upwards but never forgot what it keeps underground. If you are one of those who prefer authentic stories to tourist brochures, this is your plan. Book a tour with AGT Cali, bring your flashlight, and get ready to walk where few have stepped. The bowels of Cali await you.
Frequently Asked Questions
Is it safe to visit the tunnels of Cali?
Yes, as long as you go with an authorized guide and follow safety instructions. The tunnels open to the public, such as Canal del Pueblo and the Cathedral vaults, are in good structural condition. Avoid entering places that are walled up or have "no entry" signs. Always carry a flashlight and do not touch the walls if you see mold or dampness.
Are there tours in English or for foreigners?
Most AGT Cali guides speak basic English, but availability is not always guaranteed. If you do not speak Spanish, we recommend hiring a private guide in advance. Some operators offer bilingual tours, but they cost between $80,000 and $100,000 COP per person. Ask the Secretary of Culture for options.
Can I bring children on the underground tours?
It depends on the tunnel. Canal del Pueblo is not recommended for children under 12 due to the mud and lack of ventilation. The Cathedral vaults are safer, but the spaces are small. If you bring children, make sure they are not claustrophobic and wear appropriate footwear. Most guides do not accept children under 8.

History of the Tunnels: Engineering, Faith, and Smuggling
Cali's underground network did not emerge from a single master plan, but from several layers of history that overlapped. The oldest construction dates back to the late 18th century, when the San Pedro Cathedral built its vaults as an anti-seismic refuge. The engineers of the time, influenced by Spanish colonial architecture, designed brick and lime arches that distributed weight evenly, a technique that still keeps the crypts intact today. However, the true boom of the tunnels came in the mid-19th century, during the gold rush in the Cauca Valley. Merchants and miners needed to move gold and goods from Buenaventura to Popayán without paying the high customs taxes. Thus, they dug passages connecting warehouses, churches, and elite homes, creating a smuggling route that operated for decades.
One of the most revealing discoveries occurred in 2021, when workers repairing the Plaza de Cayzedo found hidden tombs beneath the cathedral. According to a report by El Tiempo, the remains belonged to 19th-century soldiers and colonial civilians, confirming that the vaults served not only as a refuge but also as an improvised cemetery during civil wars. This discovery rekindled interest in underground Cali and led the Mayor's Office to map the known tunnels. Today, it is known that the network extends for more than five kilometers, from the CAM (Municipal Administrative Center) to Chipichape, although most sections are sealed or in private hands.
Urban Legends: Ghosts, Treasures, and Secret Passages
Where there are historic tunnels, there are legends. In Cali, stories of ghosts and hidden treasures are as common as mangoes in the market square. One of the most popular tells of the tunnel connecting the MULI Museum (the old train station) with the San Antonio neighborhood, where the spirit of a hanged smuggler guarding a cargo of gold is said to appear. Local guides claim that on full moon nights, footsteps and the dragging of chains can be heard. Although there is no scientific evidence, the story has been passed down through generations and is a favorite during night tours.
Another urban legend speaks of a tunnel connecting the San Pedro Cathedral to the Cali River, used by priests to escape during the religious persecution of the Thousand Days' War. It is said to contain a sealed vault with gold and silver liturgical objects. So far, no one has been able to confirm its existence, but several amateur explorers have tried to find the entrance, without success. What is certain is that these stories, though unverifiable, are part of the collective imagination of the people of Cali and attract curious visitors from around the world. If you want to hear more, look for Don Carlos at the El Virrey restaurant; he claims to have seen strange lights coming from the basement of his mansion.
Cultural Importance: Memory, Identity, and Resistance
Beyond their historical value, the tunnels of Cali represent a symbol of resistance and adaptation for the city. During the armed conflict, some passages served as refuges for displaced people and as hiding places for threatened social leaders. The Casa de la Memoria, which documents these episodes, has integrated the tunnel in its basement into educational tours to show how the underground space was also a place of protection and solidarity. This cultural dimension has led the community to demand its preservation as intangible heritage.
Furthermore, the tunnels have inspired local artists. In 2024, the collective Arte Subterráneo carried out an intervention in the Canal del Pueblo, painting murals that narrate the history of the workers who built the city. The work, titled "Raíces de Ladrillo", has become a tourist attraction that combines urban art and heritage. For the people of Cali, these passages are not just remnants of the past, but living spaces that dialogue with the present. Visiting a tunnel is, in a way, paying homage to those who, from below, built the Cali we know today.
