Belgrade's brutalist New Belgrade quarter contrasted with the Ottoman-era Kalemegdan fortress above the Sava and Danube confluence, plus Europe's most relentless nightlife on the splav river clubs.
Skadarlija's bohemian quarter terraces open, Ada Ciganlija beach fills on weekends, and rakija festivals run through May in the surrounding villages.
Belgrade hits 35°C and locals decamp to Ada lake. EXIT festival in nearby Novi Sad in July is one of Europe's biggest music events.
