As nearly as a tradition every year I did a four day scooter tour from northern Italy to Croatia (island of Cres).
Beautiful serene nature, friendly people and great food (though not for vegetarians).
This tour takes approximately four to five hours oneway for I had to use a ferry from Croatia mainland to reach the island.
Well mantained, motorcycle friendly, curvy roads with hundreds of bends just to enjoy the scooters touring abilities.
Out of mainseason roads are nearly empty, inviting for day tours to explore the island by scooter and short walks.
