That is a beautiful road. We did it last year. My wife's parents have a house in Zaton. We drove from there to Dubrovnik. The roads on Hvar are pretty crazy too. I am planning on renting a bike in Italy next year and riding through the Dolomites and down to Dubrovnik if someone will rent me and a few friends bikes for that long.
Speaking of Dolomites that should be in here too. Someone post a pic.
