A guided day trip from Brasov visiting four Transylvanian castles with entry tickets included: Bran, Peles, the Sinaia complex and Cantacuzino at Busteni. The route follows the Prahova Valley through classic Carpathian scenery, and the small-group format keeps things personal. For visitors wanting to tick off the region’s grand castles in one organised outing, it packs a lot into a single day.
