Transfagarasan: Driving Romania's Best Road

The Transfagarasan is a 151 km mountain road, the DN7C, that climbs to 2,042 m across the Fagaras range between Sibiu and Pitesti, and the single most important thing to know is that its high section is only open for a few months a year. In 2026 the top reopened on 12 June and it usually stays drivable until around 31 October, weather permitting. Come outside that window and you will reach a locked barrier partway up. This page is about the road itself: when it opens, what you actually see, and how to drive it without the mistakes that catch first-timers. For the wider Transylvania loop it belongs to (Brasov, Bran, Sibiu, the vignette, the logistics), see the Transylvania road trip guide.

The short version: drive it in July, August or September for the safest odds, start early to beat the coaches, fill the tank before you climb because there is no fuel at the top, and take it slowly on purpose. The switchbacks are the point, not an obstacle between you and the summit.

When is the Transfagarasan open?

Roughly July to October, but never assume a fixed date. The alpine stretch between Balea Cascada in the north and Piscu Negru in the south sits above 2,000 m and stays buried in snow for more than half the year. The road authority clears it when the weather allows and opens a barrier at each end; in a warm year that is mid-June, in a cold one it can be the very end of the month. Wikipedia describes the pass as usually closed from late October to late June, and the Fagaras mountains site quotes an open window of roughly 30 June to 1 November. In 2026 the CNAIR road agency reopened the top on 12 June, earlier than usual.

The practical rule: if you are travelling in June or in late autumn, treat the pass as a maybe and have a plan B. Check CNAIR or the regional DRDP Brasov road authority in the days before, not a blog post from two summers ago. If you are still fixing your dates, our best time to visit Romania guide sets this opening window against the ski season, the delta and the coast so the whole trip lines up. When the barrier is up, the road runs daily between 07:00 and 21:00, and the gates genuinely close at those hours, so a sunrise start is the difference between an empty road and a crawl behind tour buses.

What is there to see along the road?

The drive stacks up its best moments in the northern half, above Sibiu. Coming from Cartisoara you climb through forest to the Balea waterfall (Cascada Balea), a long cascade tumbling from around 1,200 m, with the lower cable-car station beside it. Push on up the hairpins and you reach Balea Lake (Balea Lac), a glacial tarn at roughly 2,034 m cupped in bare rock, ringed by cabanas and, in July, wildflowers and lingering snow patches. Right by the lake the road ducks through the Balea tunnel, about 884 m long and the longest road tunnel in the country, emerging on the southern side at the 2,042 m high point.

South of the tunnel the character changes. The descent is longer and greener, and after about 50 km it reaches Lake Vidraru and its 1960s arch dam, a huge concrete curve wedged between cliffs. This southern half stays open all year, so even in winter you can drive up to the dam from Curtea de Arges; it is only the alpine crown that shuts. Most day-trippers from Sibiu or Brasov turn around at the lake and never see Vidraru, which is exactly why the southern descent feels emptier and, on a clear afternoon, arguably better.

Why is a road this remote here at all?

Because a dictator was afraid of tanks. Nicolae Ceausescu ordered the Transfagarasan built between 1970 and 1974 after the Soviet invasion of Czechoslovakia in 1968 spooked him into wanting a military route straight over the mountains, one his own armour could use if Moscow’s ever rolled in. The work fell largely to army conscripts, and it was brutal: roughly six million kilograms of dynamite were used to blast the route through solid rock. The official toll is 40 soldiers killed, though unofficial estimates run into the hundreds. In one July 1970 incident, seven were crushed by a rockfall while sheltering from a storm.

It found a very different kind of fame in November 2009, when Top Gear filmed a supercar run over the pass and Jeremy Clarkson called it “the best road in the world” on air. The label stuck, and so did the crowds; on a fine summer weekend the top can feel more car park than wilderness. That history is worth carrying with you, because the sheer improbability of the road is half of what makes driving it feel like a stunt.

How do I actually drive it? The traps to avoid

None of the driving is technically hard, but three things quietly ruin people’s day.

First, fuel. There is nothing at the summit and nothing for a long way down the far side. Fill up in Sibiu or, at the latest, at Cartisoara before you start climbing from the north; from the south, top up around Curtea de Arges. Running the tank low on the way up is the classic rookie error.

Second, speed and the crowd on the road. Forget the national 90 km/h limit up here; the hairpins are signed at 40 km/h or less, and you are sharing them with cyclists grinding uphill, pedestrians drifting into the road for photos, and slow campervans. The reward for patience is that you get to look at one of the great mountain roads instead of your bumper.

Third, bears. This is not a novelty warning. Brown bears are common along the treeline, and CNAIR explicitly cautions drivers about them; feeding one carries a fine of 10,000 to 30,000 lei. Do not stop to photograph a bear from an open window and never offer food. Enjoy them from inside a closed car and move on. Most tourists hurt by bears in Romania were injured on exactly this road after stopping to feed or photograph one, which is why it heads the list in our guide to whether Romania is safe.

On the paperwork side, you need a valid rovinieta road vignette, which almost every rental car already includes; the details of hiring a car, the deposit and insurance excess are in our car rental in Romania guide, and the practical vignette-and-distances rundown lives in the Transylvania road trip page. Most people rent in Brasov or Sibiu, the natural bases for the pass rather than Bucharest.

Can I see it if the road is closed?

Yes, partly, and this is the trick almost no guide mentions. When the top is shut for snow you can still drive up the northern half to the Balea waterfall, park, and take the cable car (telecabina) the last stretch to Balea Lake. The lift climbs about 3,700 m of cable from the lower station at 1,200 m to the lake at around 2,040 m, runs roughly 09:00 to 17:00 when the weather cooperates, and costs about 30 lei one way (children under 12 about 15). In deep winter an ice hotel is built beside the frozen lake, rebuilt each year from blocks cut out of Balea itself, reachable only by that cable car. So a February trip to the summit is possible; you just leave the car below and ride up.

Which direction, and how long does it take?

If you are basing in Transylvania, drive it from the north: start at Cartisoara off the DN1 near Sibiu, climb to Balea, and either turn around at the lake or carry on south over the tunnel toward Vidraru and Curtea de Arges. Taken as a there-and-back from Sibiu to the lake and home, budget a full day with stops, not a couple of hours; the road is short in kilometres but slow by design. If you cross the whole 151 km south to Pitesti, you are committing to a one-way traverse and a long loop back, which only makes sense if Bucharest is your next stop anyway.

The most common plan is a day trip from Sibiu or Brasov: leave at dawn, be at Balea Lake before the coaches, walk the lake, then descend before the afternoon light and traffic thicken. If you would rather not drive the hairpins yourself, a private day trip with a driver turns the pass into a sit-back day and lets everyone watch the scenery instead of the road. Either way, sleep the night before somewhere near the foot of the mountains; our Sibiu travel guide and things to do in Brasov both set up good bases, and the pass slots neatly into the wider 7-day Romania itinerary.

Drive it once and you understand the fuss. Time the season, respect the bears, fill the tank, and let the road be slow. The Transfagarasan does the rest.
