Walked the Veliki Strbac trail with park rangers - a trail leading up to wonderful views of the Iron gates, the Djerdap park and Romania Portile de Fier park opposite. Amazing populations of butterflies, wonderful forest and well marked trail. Whilst there make sure to also visit the Mesolithic 9000 year old site at Lepenski Vir near Donji Milanovac http://www.lepenski-vir.org/
