Though it’s a stunner in its own right, the Adriatic gem of Dubrovnik achieved recent fame as a backdrop for HBO’s hugely popular series Game of Thrones, where it doubled as King’s Landing. Climb the 175 stairs up to Lovrijenac Fortress to see the site of the tournament honoring the fictional King Joffrey. A beautiful spot just outside Pile Gate played Blackwater Bay in the series. The lush 15th-century Trsteno Arboretum, 20 minutes from Dubrovnik, was used to film all the palace garden scenes. While you can do a self-guided walk (there’s a map mounted on an Old Town wall to help), the Game of Thrones tour from Calvados Club is worth the splurge. Guide Lucija Podić, who worked as a makeup artist on the show, will share insider intel you’d never get otherwise.
