If you’re traveling to Apulia and longing to see one of Italy’s most spectacular underground sights, the Castellana Grottoes should be high on your list. For around $29, you can join an official guided tour that takes you into the heart of this vast underground labyrinth just outside the charming town of Castellana Grotte. With a knowledgeable guide leading the way, you’ll see dazzling stalactites, stalagmites, flowstones, and the breathtaking White Cave, known for its alabaster-like whiteness.
What we love most about this experience are the stunning visuals—the interplay of natural light and mineral formations creates an otherworldly atmosphere—and the fact that you skip any lines, making your visit smooth and stress-free. Plus, the White Cave alone justifies the tour price, offering an experience unlike anything you’ll find elsewhere.
A possible consideration is the group size and noise level—some reviews mention difficulty hearing the guide amidst large crowds or from lack of an audio system. If you’re sensitive to tight spaces or looking for a quieter experience, this is worth keeping in mind.
This tour suits travelers who appreciate natural beauty, geological wonders, and authentic experiences. It’s especially good if you want a comprehensive, guided understanding of the caves rather than a solo exploration.

Your journey begins in the Grave, the most extensive cavern of the system. It’s a spacious, naturally connected space that measures roughly 100 meters long, 50 meters wide, and 60 meters deep. Here, you’ll see stalagmites rising from the ground and the Cyclops stalagmites, a dominant feature that’s often highlighted as one of the most impressive formations. The guide will point out how these formations develop over thousands of years through mineral deposits left by dripping water.
Many visitors note the magnetic quality of this first space—the enormity and natural beauty immediately draw you in. One reviewer exclaims, “Pazzesco, la Grotta Bianca è incredibile!” which translates to “Crazy, the White Cave is incredible.” That sense of awe is what makes this place special.
Navigating the Corridors and Multiple Chambers
From the Grave, the tour winds through a series of corridors and chambers, each with its unique character. The pathways are generally well-maintained but involve some walking and bending, so comfortable shoes are a must. Along the way, you’ll observe flow-stones, columns, and intricate crystal formations—each with imaginative names inspired by explorers’ creativity. These formations are still growing, which means the caves are constantly evolving.
While the route isn’t overly strenuous, be prepared for some narrow passages and uneven floors. The temperature inside remains around 16.5°C, so bring along a light jacket or warm top to stay comfortable.
The Highlight: The White Cave
The most anticipated part of the tour is the White Cave. Known as the most beautiful in the entire system, it’s distinguished by its crystalline, alabaster whiteness, which gives it an almost surreal appearance. Visitors often describe it as an “incredible spectacle”—one that will stay with you long after you leave. According to reviews, this cavern is “defined for its richness and whiteness as the most splendid in the world.”
Access to the White Cave is available only if you opt for the full tour, so if you want to see this natural masterpiece, make sure to select that option.
Practical Details and Logistics
The guided tour typically lasts about an hour, but it can vary depending on group size and questions. The tour includes skip-the-line entry, which is a real plus during peak season, saving you hours of waiting. The guides are bilingual, offering explanations in English and Italian, though some reviews mention that language barriers could be an issue, especially if no audio system is used.
You’ll love the way the guides manage large groups—though some mention that sounds can be drowned out due to noise, and the pace can feel a little hurried, especially during busy times. Bringing along patience and a good pair of shoes will help maximize your enjoyment.
Walking through the caves is like stepping into a natural cathedral. The ceiling and walls are adorned with stalactites hanging like chandeliers, while the floors are decorated with stalagmites that seem to grow from the ground like natural sculptures. The flow-stones create gentle waterfalls of mineral deposits, and the columns—where stalactites and stalagmites meet—are particularly striking.
We loved the way the guide’s storytelling brought the formations to life—sharing legends, names, and the geological processes behind them. Their enthusiasm made the experience more personal and memorable. One guest remembers how the guide managed to make the formations seem almost alive.
