A full-day loop from Brasov taking in the region’s most famous castles: Bran, long linked to the Dracula legend; the lavish royal palace of Peles in Sinaia; and the neo-Gothic Cantacuzino Castle at Busteni. The route runs through the Prahova Valley beneath the Carpathian peaks, with skip-the-line entry and a guide covering the history along the way. It is the most efficient way to see Transylvania’s headline castles in a single day.
