Bosnia, Montenegro

Hi,

I'm planning a trip from Zagreb (Croatia) , Bosnia, Montenegro and back along the cost of croatia.

So far the route is as followed planned:

Zagreb - Bihac (Bosnia) - Jajce - Travnik - Sarajevo - Foca - Zabljak (Montenegro) - Niksic - Kotor - Dubrovnik - Split.


Does anyone has experience about roads, traffic?
Or any other useful information?

THANKS FOR EVERY HELP!!
Felix
