Transport
Bac spre Ostrov
We do not write up a ferry at Ostrov just because a village sits on the bank. If there is no documented public service, the page says so.
Verifică
Town hall, ramp, notice at the bank. A group of locals with a boat is not a timetable.
Podul
Road link to the other bank, where it exists, is not replaced by an invented ferry.
Ostrov ca loc
The village and Dervent have Danube context elsewhere. Here it is only the ferry question.
