The Transfăgărășan is one of Europe’s most dramatic mountain roads, climbing through Romania’s Carpathians in a sequence of sweeping curves and tight hairpins. Built across challenging terrain, it is as compelling for its engineering as for its scenery. Seasonal access and mountain weather shape the experience, making preparation and respect essential to the journey.
