Commissioned by Nicolae Ceaușescu as a military fallback route after the Soviet invasion of Czechoslovakia in 1968, the Transfăgărășan (DN7C) remains Romania’s most spectacular high-mountain road: roughly 90 km of switchbacks between Wallachia and Transylvania, voted the world’s best road by the TV show Top Gear.
A high-mountain climb across the Southern Carpathians
From Curtea de Argeș, the road first skirts the Vidraru dam and reservoir and passes below Poenari Fortress — the genuine “Dracula’s Castle” of Vlad the Impaler — before the real climbing begins. Over roughly 85 km and 1,890 m of cumulative elevation gain, the route winds up in steady switchbacks to the Capra-Bâlea tunnel (887 m, Romania’s longest road tunnel), which opens onto the glacial Bâlea Lac, at 2,034 m — the high point of the road.
Getting the ride right
A compact crankset is welcome for the 10% ramps on the final switchbacks below the summit, along with front and rear lights to get through the Capra-Bâlea tunnel safely. Supplies are scarce once you’re past Vidraru: it’s best to set out with enough food and water for several hours, as the weather can turn abruptly even in high summer at this altitude.
When to go
The high-altitude section, between Piscul Negru on the south side and Bâlea Cascadă on the north side, is closed by snow for much of the year: it typically reopens in late June, sometimes not until early July if snow lingers, and closes again in late October or early November. Exact dates vary from year to year depending on the weather — the lower stretches, on both the Curtea de Argeș and Cârțișoara sides, stay rideable year-round.
Good to know
Curtea de Argeș offers enough services for a stopover before the climb, while Bâlea Cascadă, at the foot of the final switchbacks on the north side, has a 3,700 m cable car running straight up to Bâlea Lac — usable even when the mountain road itself is closed by snow. Sibiu, roughly 70 km to the north, remains the best base for combining the ride with an airport and a wider choice of accommodation.
