I have planned a trip to Carpathia montains for next week (5/12-08-2013). It will start from Bursa / Turkey. I will go trough Bulgaria and spend most of the trip in Romania. I will stay 5/6 night in Romania and would like to see Bucharest, Sibiu, Brashov and Sighisoara cities. Its my first international trip and i dont know regional paper jobs beside green card. Do i need any other road permision card etc. Also, does anyone suggest roads or places that i have to see around mentioned cities?
