We'll leave the ship for an energetic walk to the Petrovaradin Fortress. We'll stroll along the riverfront before climbing the 200 steps up to the fortress. An exceptional work of 18th-century fortification engineering, it is one of the largest, most-complex and best-preserved artillery bastions in this part of Europe. It also contains a vast system of underground military galleries, with mine and listening tunnels, distributed across four levels running almost 10 miles long. The view from the fort is splendid, and we'll enjoy a snack during our hike.
