I am travelling to Istanbul from Sofia on the 14th of June. I have a Eurail pass and would like to know if I can use the whole of this journey? If so, what are the changes to buses for this journey? How long between buses/trains and what provisions of shelter are there in between times?
Global Eurail pass is also valid in Turkey. However connected bus services may be disturbing, please see up-to-date details at below train link.
