This series of grottoes, 40 kilometres southeast of Bari, are the biggest ones in Italy. They are 3 kilometres long and 71 meters deep and include long underground passages and deep caves covered with hundreds of stalactites and stalagmites formed over thousands of years by water erosion of the calcareous rock.
Do & See
Bari, a busy port city on the Adriatic coast might not quite yet be able to compete with Italy's other tourist magnets, but it's not likely to stay this way for long: the charming port town does not lack in history or culture. Bari has many stunning sites to offer, such as the Cattedrale Di San Sabino, known as one of the most important attractions in town, and the Castel Del Monte, a unique medieval manor house, 70 kilometres from the centre of Bari. Additionally, be sure to enjoy a walk in the beautiful Orto Botanico or discover the Grotte Di Castellana — the famous caves of Castellana — and visit the Old Town to capture some photos of the medieval buildings, take a stroll by the harbour, enjoy the beautiful sea view, and watch fishermen at work. All the tourist highlights can easily be visited on foot.
