Transfagarasan Highway

The Transfagarasan’s high section above 2,000 m is closed by snow from late October to late June — roughly eight months of the year — which leaves late June to October as the only dependable window to drive it. The road is 90 km of DN7C topping out at 2,042 m with more than 830 hairpins, it costs nothing in tolls, the hairpin sections carry a 40 km/h advisory against Romania’s 90 km/h open-road default, and the drink-drive limit is a flat 0.0.

Your case: If your dates sit near either end of that window, the only answer that counts is the one on the day you set off — and Romania’s driving rules cover the rovinieta vignette the approach roads need even though the Transfagarasan itself is free.

Practical Tips

• Check road status at infotrafic.ro before going — the pass closes without much notice
• The northern descent has tighter, more dramatic hairpins than the southern climb
• Arrive before 9 AM to beat the tour bus convoys that clog the hairpins
• Balea Lake area gets very cold even in summer — bring a jacket for 2,000 m altitude
• Combine with the Transbucegi or Transalpina roads for a multi-day mountain driving tour
