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.

The extraordinary Old City of Bari largely consists of narrow and winding streets, making it a charming place to stroll around. You'll find all the important medieval monuments, such as the Swabian Castle and many churches, including the Cathedral of San Sabino and the Basilica of San Nicola, as well as plenty of bars and restaurants.

Uyun Al-Jiwa — literally "the valley’s ponds" — is often referred to as the oasis celebrated by Arab poets for its significance in several poetry collections known as the Suspended Odes (Mu’allaqat). The area is known for the ancient Banu Abs communities that lived here since prehistoric times. Depicting the lifestyle of ancient people, several Thamudic rock paintings can be found in the Al-Jiwa region — particularly in Al Hanadir, 15 km outside the city. Be sure to visit the mud-and-adobe Al Margab Watchtower. Take a walk through the Old Uyun — a collection of houses built of clay and mud. Get souvenirs from the vibrant Old Souq and take a photo of the Antarah Rock. Also known as the Lovers' Rock, this precariously perched boulder is rumoured to be the place where the celebrated poet Antarah bin Shaddad met with his sweetheart Ablah.
