Follow the flow of the mighty Danube River as you depart from Belgrade to the Golubac Fortress. Built on inaccessible cliffs at the widest part of the Danube, this medieval fortification welcomes you with its mystical towers that tell stories resembling a true fairytale. Climb up one of the towers and you’ll understand why locals say that the Danube looks like the sea from this point. Stand on one of the best-preserved fortresses in Serbia, for an almost aerial view of the Danube and its mirror-like surface.   Next, journey back to the Mesolithic era at the archaeological site of Lepenski Vir, a prehistoric urban settlement. Uncover information about ancestors from the 6th century BC including their way of life and mindset, showing that ancient Homo sapiens had been much more advanced than predicted. This museum, unique by theme, location, and construction, will leave you inspired and in wonder.   Following your history lesson, enjoy a reward at the eco-ethno complex of Kapetan Mišin breg where you can take in enchanting views of the Djerdap gorge. The complex, named after a very respected captain, offers you an open-air gallery called “Man, wood, water” featuring a collection of wooden and stone sculptures.   Take a deep breath, chitchat with the hosts, and gaze far into the distance as you feel more connected to the events and sites of the Danube River as experienced from the different epochs before returning to Belgrade.
