Underground Toledo: Roman baths, dungeons, and secrets beneath the city

Visiting Toledo often means wandering through historic streets, marveling at its medieval charm and layered history. But if you’re looking to see a different side of this ancient city, an underground tour offers a curious and captivating perspective. We’re reviewing a guided experience that takes you beneath Toledo’s surface to explore five private underground sites, including Roman baths, dungeons, and hidden passages — all in Spanish.

What makes this tour stand out? First, the exclusive access to spaces most travelers never see, thanks to private keys and careful planning. Second, the mix of underground exploration and outdoor walks gives a well-rounded picture of Toledo’s history and its secret corners. Third, the great value at just $14 per person makes it accessible for most travelers.

This experience is ideal if you love history, archaeology, or underground mysteries. It’s especially suited for those eager for an authentic, behind-the-scenes look at Toledo’s past, rather than just surface-level sightseeing. Travelers with a sense of adventure and curiosity about medieval and Roman history will find this tour both engaging and enlightening.

What You Can Expect from the Tour

This guided walk begins at the Rutas de Toledo office, located conveniently behind the Cathedral, where your adventure is set to start. From there, the guide—who speaks only Spanish—leads you through the labyrinth of Toledo’s narrow streets, sharing stories and curiosities about the city’s underground past.

The true highlight is the private Roman baths — considered the most impressive underground site in Toledo. These baths are not accessible to the public, as they are only opened with the guide’s own key, adding an exclusive feel. With their vaulted ceilings, ancient stones, and preserved mosaics, they offer a real glimpse into Roman life in the city. One reviewer described it as “the most impressive underground site in Toledo” and emphasized that it’s a unique experience, not duplicated in other guided tours.

Next, your journey takes you to the Dungeon of the Posada de la Hermandad, part of a museum and accessible through a private basement. This space features wooden models of Toledo’s monuments, which appeal especially to visitors traveling with children or history enthusiasts. “Perfect for kids,” as one traveler noted, with the space providing a tangible connection to Toledo’s medieval past.

Other private sites include the basement of a Jewish residence, which offers insights into the city’s Jewish quarter, along with an underground exhibition. These spaces are carefully chosen for their historical significance and uniqueness, making each stop feel special.

Note: As of July 2025, the Roman baths site will change, shifting to a different private Roman bath location. The tour promises this new site will be equally intriguing, though details are still emerging.

The Underground Passages and Their Significance

The underground network of Toledo is a complex web of caves, galleries, and cellars, many of which have survived through centuries. The tour focuses on five sites, most of which are not open to the general public — which means this experience offers a rare chance to step behind the curtains of Toledo’s subterranean world.

The tour’s approach isn’t just about walking through underground corridors; it’s about uncovering the stories, mysteries, and curiosities behind each space. The guide narrates anecdotes about the history of each site, from Roman times to medieval periods, and shares facts that are often overlooked in standard city tours.

The Outdoor Walks and City Exploration

Aside from the underground visits, the tour involves a pleasant walk through Toledo’s streets. This outdoor component lets you see the city’s charming alleyways, historic gates, and architectural details. The route isn’t fixed, and the tour can end at any underground site, giving some flexibility to the experience.

One reviewer highlighted the “nice walk discovering the unknown part of Toledo,” appreciating the guide Bruno’s engaging explanations. The outdoor segments add context and help you understand how these underground spaces fit into the broader history of Toledo.
