In comparison with Ukrainian distances, this is not that far away. But, considering mountaneous landscape, it may take a lot of time to go round all those sights due to the twisting road. Anyway, I think it'd be great to rent a car to see this beauty with my own eyes in the future - including Bran, of course!

For example, my mother's cousin and her husband travelled around the Balcans on their own car. As far as I remember they visited Moldova, Romania, Serbia and Chroatia - they got a great deal of excitement and saved lots of money (while bus tours cost much more...).
Thanks for the interesting information, Diana and Seli!
I hope I'll be able to realize my plans.
