Transfagarasan (Romania)

The Transfăgărășan's 56 miles cut through Romania's Carpathian Mountains with tunnels, viaducts, and switchbacks climbing to 6,699 feet, a route built by dictator Nicolae Ceaușescu for military purposes. Jeremy Clarkson called it "the best road in the world" on Top Gear in 2009, though #2 Stelvio Pass boasts more hairpins. The northern descent features sweeping curves along Balea Lake, making it one of Europe's most photogenic drives, especially in late June when snow banks still line the road. Open only four months per year (late June through October), each trip feels exclusive. With an average gradient of 6.3% and 90% of corners having no guardrails, driving here demands vigilance but rewards with unforgettable mountain vistas.
