Corsica belongs to France, Sardinia to Italy and the culture, landscape, nature, and of course the language is different. Perhaps that is why it is so interesting to travel?
Corsica has a long history of "independence" but it is still a part of France. Even today you find a movement for total independence, something not existing in Sardinina. This could be explained by the difference between the countries. In France all decisions have to come from Paris and that leaves very little for the local government. In Italy the government in Rome has almost never been strong and Sardinia and Sicily are able to make many of their own decisions.
Bonifacio itself is a medieval town built on a necropolis. It was a Genoese fortification and the streets are really narrow. Now in mid-October most of the shops have closed and the town is preparing for the winter. Bonifacio is today mostly a small port for sailboats.
We did not sail until midnight so some of us went out to try Corsican cooking in one of the many restaurant along the waterfront.
