Assuming you head down through Montenegro, try this (below)

When approaching to Ferry crossing in Bay of Boka Kotorska at Kamenari, don't stop on ferry and waste time, turn left, and pass by two narrow curves between old houses of Kamenari.
You will enter to the one of most beautiful bays in the world.
Next time you will know what to do :)
I missed the bay loop when I did it and used the ferry. I've not been back since then so though :( but I loved the coast road, espcially in Croatia - so much so that I did it in one go.
