I rode down to Croatia last year and loved it, broke down on the Bosnian border and had to cut the trip a little short then but made it home fine. I really want to see more of Croatia this year but also want to go across to Bulgaria and Romania, I really don't fancy riding to the bottom of Croatia just to turn around and head back up again but have had conflicting advice on the best way to cross over to Bulgaria. I've been told Serbia is a no go? Same for crossing the whole of Bosnia/Herzegovina? Montenegro-Albania-Macedonia looks do able but I'm told insurance is an issue? What have you done and what would you reccomend?
