This is a short run on a path along the left bank of the Sava River. It’s in the New Belgrade area, developed after WW2 very much in the Soviet style, with sections of brutalist apartment buildings located in some 70 ‘Blocks’.

The east end of the paved path starts off Dr. Agostina Neta in Block 70a, and runs for 2.5 km west to a ferry stop of Dr. Ivana Ribara. There’s a path along the water, and additional paths in the park that runs along most of this area between Blocks 70a and 71.

Add-Ons: You can explore additional streets in the New Belgrade area, where there are numerous small parks and interesting architecture from the Soviet era. Another great option is to take the short ferry to Cignalija and run all or part of the lake loop — one of the most popular runs in Belgrade.
