This full-day trip from Cluj takes in two of Transylvania’s great historic sites. The mighty Corvin Castle at Hunedoara is one of Europe’s largest and most dramatic Gothic castles, bristling with towers, drawbridges and turrets straight from a fairy tale. The tour continues to the star-shaped Alba Carolina citadel in Alba Iulia, a vast Vauban fortress with grand baroque gates and Habsburg architecture. With comfortable transport and a guide, it is a rewarding journey through the region’s layered history.
