Friendly warning! We're working hard to be accurate. But these are unusual times, so please check that venues remain open.
Jump a cab or tram Nos.6, 7 or 8 over the Sava river to Novi Zagreb and the Sunday morning flea market at Hrelić. Many of the goods here are cheap – clothes, CDs, sports shoes – but you’ll also find piles of oddities and rarities from all over the Balkans.
