If you’re looking to uncover a side of Cagliari that most visitors miss, an Underground Cagliari tour might just be your perfect match. This two-hour adventure takes you below the city streets, revealing a network of tunnels, crypts, and ancient ruins that tell stories spanning centuries. It’s a great way to escape the daytime hustle and experience a different, cooler perspective of Sardinia’s capital.
What we really appreciate about this experience is how it combines genuine historical intrigue with practical comfort—the cool underground spaces provide relief from the midday heat, and the guide’s storytelling brings the sites to life. Plus, with the opportunity for some atmospheric photos in candlelit tunnels, it’s a trip that feels both educational and a little mysterious.
On the flip side, a key consideration is that parts of this tour aren’t suitable for everyone. If you suffer from claustrophobia or have mobility difficulties, this might not be the best fit. The tour involves walking through some tight, dark spaces, and the overall pace might be a bit much for those needing extra assistance.
This tour suits history buffs, curious travelers wanting a unique experience, or anyone eager to see Cagliari from a different angle. It’s especially appealing if you’re interested in a small-group feel and appreciate knowledgeable guides who can share stories in both Italian and English.

What to Expect from the Underground Cagliari Tour

This experience offers a well-rounded peek into parts of Cagliari that aren’t usually on the tourist radar. Starting at the Salesian School tunnels near the botanical gardens, you’ll meet your guide and venture into the underground shelter used during WWII. These tunnels are still lit only by candles today, creating an atmospheric setting where you can almost hear echoes of the past.
The next stop is the Crypt of Santa Restituta, a natural cavern that transformed into a religious site in the 5th century. As one reviewer noted, “The church is dug out of rock and has an interesting history back to the Phoenicians,” which hints at the multi-layered past hidden beneath the city. Walking through this crypt, you get a sense of how underground spaces have been repurposed over centuries.
Your final stop is the Museo del Tesoro e Area Archeologica di Sant’Eulalia, an archaeological underground area where Roman roads and ruins are still visible. Here, you’ll get a taste of Cagliari’s ancient past, and guides often point out features like old anchors or paved Roman roads, connecting you straight to the city’s historical roots.
