The Basics

Take a spelunking adventure through the Torri di Slivia Cave and discover an underground world formed by thousands of years of water running through stone. The guided tour, led by a speleologist (cave specialist), follows an internal walkway and includes information about local geology. This cave is an easy day trip from Trieste and can be combined with visits to the Postojna Cave and Predjama Castle across the border in Slovenia.

The elegant city of Trieste is located on the border between Italy and Slovenia, along the Adriatic coast, and is an excellent example of Italy's fascinating diversity. This wealthy capital has survived successive waves of invaders and rulers since the Romans, and it was annexed by Italy from the former Austro-Hungarian empire after World War I. In the center of the city, the influence of millennia of conquerors is evident, with Roman ruins sitting next to elegant Viennese palaces and the Catholic church of San Giusto, the Serbian Orthodox church of San Spiridione, and a Jewish synagogue all lying within a one-mile radius. The city is also known for its beautiful Piazza dell'Unità d'Italia (Piazza Grande) which looks out over the sea, the Borgo Teresiano neighborhood’s Grand Canal (Grande Canal), and the Miramare Castle, which is just outside the city.
