In the town of Castellana Grotte, you'll tour the longest underground karst caves in Italy, over 3 km of path reserved for visitors with a speleological guide. The Castellana Caves reveal a hidden world made of huge columns, stalactites and stalagmites of calcium carbonate, curtains that look like alabaster, and cavities that recall Dante's inferno.
