I'm hoping to see some of this area this August. I don't really have a proper map of Slovenia yet, but, fiddling around with Google Earth, it looks like there is a possible loop?
I was thinking to cross over from Italy at Nova Gorica, then north.
East of Tolmin a short ways, it appears there is a paved? route over the mountains, via Grahovo, Bohinjska Bistrica, and Nomenj that continues on to Bled. Google identifies the roads as 403, 909, and 209, I think?
Has anyone been this way? gody? Tim? Anyone? From there I would loop back around over Vrsc pass and then back into Italy.
