Cala Rossano is a porto communale and is free alongside the outer concrete wall, but beware the line handlers who are aggressive in taking lines and charging for their service. In the same bay there are two private very expensive pontoons.
A little further along the coast lies Porto Vecchio, a unique little harbour built by the Romans for galley construction, well worth visiting. Berthing at this port is available but for a few yachts at a charge but you will be attaching your lines to rock-carved bollards built two thousand years ago.
Ashore: limited shopping in town.

I understand that the expensive private pontoons sometimes offer special 25 euro prices to boats anchored outside after 18:30. The port is open to swell often and is the location that multiple ferries arrive at. If you are less than 15m LOA then try the old Roman port next door.
