Explore the stunning Castellana Grottoes with a guided tour, discover spectacular rock formations, and see the White Cave in Italy’s captivating underground system.
Our review of the Castellana Grottoes official guided tour covers a journey into one of Italy’s most impressive cave systems. For just $29, you get a 50 to 100-minute experience that combines natural beauty, fascinating formations, and insightful storytelling. With reviews indicating a solid 4.4 out of 5 from over 100 travelers, it’s clear this tour offers real value for anyone eager to see the underground wonders of Apulia.
What we particularly like about this experience is how it balances spectacular scenery with informative guidance. The highlight, undoubtedly, is the White Cave, renowned for its alabaster-like whiteness, showcasing the caves’ extraordinary mineral richness. On the other hand, some visitors mention that navigating large groups can occasionally make it tricky to follow the guide closely, which is worth considering if you prefer a more intimate experience.
This tour is ideal for those interested in natural wonders, geology enthusiasts, or travelers seeking a memorable underground adventure without the need for extensive physical exertion. It’s accessible, informative, and visually stunning — perfect for families, curious travelers, or anyone looking to add a unique experience to their Italian itinerary.


The tour starts just 1.5 kilometers outside the charming town of Castellana Grotte, making it a convenient stop during a day exploring Apulia. Once you arrive, skip the lines with your pre-booked ticket and meet your live guide — fluent in both English and Italian — who will lead you through the underground labyrinth.
The first cavern you’ll enter is the Grave, the largest and most expansive chamber of the system, measuring 100 meters in length, 50 meters wide, and 60 meters deep. As you step inside, the size of this space is immediately striking. The ground is dotted with stalagmites, including the famously impressive Cyclops, a cluster of stalagmites that rise like a watchful eye in the center of the cavern.
The tour winds through corridors that vary dramatically in shape and size, giving a real sense of the caves’ natural formation over thousands of years. The guides excel at pointing out interesting formations and explaining their origins, often referencing the imaginative names given by early explorers. For example, you might hear about shapes that resemble animals or mythical figures, making the journey both educational and fun.
Throughout your walk, you’ll encounter the typical stalactites hanging from the ceiling, stalagmites rising from the ground, flow-stones creating smooth, layered surfaces, and towering columns formed when stalactites and stalagmites meet. The formations are illuminated artistically, highlighting their intricate textures and colors, which range from stark white to subtle earth tones.
The ultimate highlight of the tour is the White Cave — often called the most beautiful in the entire system. As one reviewer notes, “The White Cave, defined for its alabaster-like whiteness, is simply breathtaking.” Its extraordinary brightness and the richness of its mineral deposits make it seem otherworldly. The guide will detail how the cave’s mineral composition gives it that stunning appearance, and you’ll have ample time to take photos.
At €29, this guided tour offers excellent value considering the complexity and beauty of the caves. The entrance fee alone covers access, and the guided component enhances the experience with expert commentary and historical context. Reviewers mention that the guides are knowledgeable, with some noting that the descriptions of formations and cave history make the visit more engaging.
A few travelers have mentioned that large group sizes can sometimes make it difficult to follow the guide or see formations up close. One reviewer suggested that the tour might be somewhat rushed, especially during peak times. Also, some noted that a few stalactites appeared to be broken off, possibly to make passages more comfortable — a reminder that natural caves are subject to human intervention and preservation challenges.

If you’re curious about geology, enjoy natural wonders, or want a visually stunning experience, this tour hits the mark. It’s especially suitable for those who appreciate guided storytelling and don’t mind a modest amount of walking. Since it’s not accessible for wheelchair users or those with severe claustrophobia, check your comfort level first.
The Castellana Grottoes guided tour showcases Italy’s underground beauty with impressive formations, a spectacular White Cave, and engaging storytelling. It’s a well-priced, memorable experience that offers both visual awe and education. The natural grandeur of the caves makes this a must-do for lovers of geology or anyone seeking a unique adventure off the beaten path in Apulia.
Whether you’re traveling with family, friends, or solo, this tour provides a fascinating glimpse into one of Italy’s most breathtaking natural features. Just remember to wear comfy shoes and bring a warm layer — the caves are cooler than the outside world!
