Spelunkers are in their element at Grotta Monte Cucco, one of Europe's most spectacular limestone caves, with a 30km maze of galleries reaching up to 900m deep. Those up for a challenge can delve into its underground forest of stalactites and stalagmites on a guided two- to three-hour discovery tour. For more details on the caves and park, stop by the info point in the nearby village of Costacciaro.
