Romania's most legendary alpine road — 90 hairpins, Vidraru Dam, and Balea Lac at 2,034 metres. Built as a military route through the Făgăraș Mountains. WARNING: Closed outside roughly June–October due to snow and avalanches. Sustained 8–10% gradients will test T3 cooling and brakes; carry extra coolant and use engine braking on descent.
The Transfăgărășan — DN7C — is Romania's answer to the Stelvio and the Grossglockner combined, a road so dramatic that Jeremy Clarkson once declared it the best driving road in the world. Built between 1970 and 1974 on the orders of Nicolae Ceaușescu as a strategic military route through the Făgăraș Mountains, the Transfăgărășan climbs from the southern foothills near Curtea de Argeș to the glacial lake of Balea Lac at 2,034 metres, threading through more than ninety hairpin bends, two long tunnels, and the monumental Vidraru Dam. The southern ascent from Curtea de Argeș is the classic approach for van travellers: the road rises steadily through forested valleys before breaking into open alpine terrain where every switchback reveals another layer of the Carpathian skyline.
Vidraru Dam is the first major landmark — a 166-metre concrete arch holding back a reservoir that powers a hydroelectric plant visible from the road's viewing platforms. Beyond the dam, the gradient intensifies. Sections regularly exceed 8% and touch 10% on the final climb to the pass, sustained grades that will push an air-cooled VW T3's cooling system to its limit. The advice from experienced Bulli drivers who have made this crossing is consistent: climb in first or second gear, stop at every pullout to let the engine breathe, carry spare coolant, and never attempt the pass on a hot afternoon in August without checking your fan and oil cooler first. The descent north toward Cârțișoara demands equal respect for the brakes — use engine braking throughout and avoid riding the pedal on the long downhill sections after Balea Lac.
Seasonality defines the Transfăgărășan more than almost any other road in Europe. DN7C is typically open from late June or early July through October, sometimes closing earlier if early snow arrives on the high ridges. Outside this window the road is gated and impassable — attempting it in winter is not adventurous, it is illegal and dangerous. Even within the open season, weather at Balea Lac can turn from sunshine to sleet in minutes; carry warm layers regardless of the forecast. The northern approach from Sibiu via the Balea Lac cable car is an alternative when the southern section is closed for maintenance, though the full through-drive requires the pass to be open end to end.
For slow van travel, allow a full day. Start early from Curtea de Argeș, fuel up completely — there are no petrol stations on the pass itself — and plan to spend an hour at Balea Lac before descending. Camping is possible at the lake's parking area in summer when facilities operate, and the town of Cârțișoara at the northern end offers guesthouses and a small shop. The Transfăgărășan is not a road you drive for efficiency; it is a road you drive because the Carpathians, seen from ninety hairpins above the clouds, are one of the great experiences of European slow travel.
