This tour ticks off a pair of Serbia’s must-see antique attractions. After a 15-minute drive from the port, you’ll arrive at Lepenski Vir – an 8,000-year-old archaeological site that’s been dubbed ‘the first city of Europe’. In the museum here, you’ll watch a video presentation about the history of the area. Then you’ll head into the main hall to see what’s left of the old settlement. These remains were discovered in 1960, and historians believe they date as far back as 6500 BC. You’ll see where the old huts used to stand, as well as artefacts like carved stone heads and tools. When you’re finished, you’ll travel to the town of Golubac’s waterfront fortress. This giant stronghold was built in the 14th century, and sits on the shore of the Danube. During a riverside stroll, your guide will tell you about the battles that took place here between Hungary and the Ottoman Empire. And before you start the journey back to the port, you’ll have some free time to explore the castle on your own.
