Skip the expensive private boat tours and book a kayak trip to Great War Island instead. You get up close to the river’s untouched ecosystem for forty bucks, which is a steal compared to the multi-hundred dollar yacht rentals. Spend three hours paddling the confluence where the Sava meets the Danube. Show up for a morning session to beat the midday heat and the heavy river traffic. It is the rawest way to see the city skyline.
