Romania's Transalpina is a road that earns its reputation. Stretching 148 kilometres from Sibiu south to Petroșani, it hauls you up to 2,145 metres at the Urdele Pass, making it the highest paved road in the country and a genuine high-alpine sufferfest by any measure. Most riders spread it across two days, staying overnight in Novaci or one of the basic but characterful pensiuni dotted along the lower slopes.
The climbing starts gently enough through forested foothills, but from Obarsia Lotrului northward the road rears up in long, exposed ramps where the gradient regularly bites above ten percent.
Surface quality is paved throughout but honest about its age — patches are rough in places, and the road is narrow enough that sharing it with tourist cars and occasional logging trucks demands alertness, particularly on blind hairpin bends.
Riding south to north, Petroșani to Sibiu, gives you the bigger climbs early and a long descent finish, though many prefer the opposite direction for the dramatic build to the summit plateau. Up high, the landscape opens into vast alpine meadows where sheep flocks drift across the tarmac with complete indifference to your schedule; shepherds and their dogs are part of the daily fabric here.
Bike hire near the route is essentially non-existent, so bring your own machine or arrange rental in Sibiu city before departing. Train connections serve both Sibiu and Petroșani reasonably well for those returning without a support vehicle. Accommodation is thin above Novaci, so book ahead. The road can carry snow well into May and closes earlier than you'd expect in autumn.
Go in late June through early September; carry two spare inner tubes and a warm layer, as summit temperatures drop sharply even on clear days.
