What Travellers Say
Reviews Summary
Visitors consistently praise Grotta di Santa Barbara as an 'out of this world' experience, comparing it to an 'underground cathedral' with stunning alabaster-like formations and a beautiful turquoise lake. The unique journey through the mine via train and elevator is a highlight, and the guided tours are informative and friendly. Some minor drawbacks include the need for advance booking and the 'cozy' elevator ride.
"This place is out of this world. Looks like an underground cathedral, made of alabaster columns, and topped with ivory pinnacles. There are stalactites and stalagmites everywhere, along with other formations. And, to top it off, an amazingly clear and turquoise lake sparkles at the bottom of the cave. Unbelievable..."
