• Free skatepark open to anyone with a skateboard, rollerblades or a bike, and it hosts local and international competitions
• Fortress views across the river, since the park faces Kalemegdan and the old town from the Sava and Danube banks
• Winter waterbirds off the banks facing Great and Little War Island, a good season for a birdwatching walk

Ušće Park spreads over 52 hectares of lawns, paths and trees on the point where the Sava meets the Danube, the largest park area in the city. Kids can bike the paths, watch the skaters at the skatepark, and look across the water to Kalemegdan fortress and Great War Island.

In winter, birdwatchers come for the rare waterbirds off the banks.
