Nonza is a city in Corsica.
Nonza ca be accessed on road. It is situated on the Western shore of Cap Corse. The traffic is fairly dense.
The town is very small so you are advised to walk. Be careful as the town is situated quite high above the shoreline.
The Genovese tower is a nice landmark. The Citadel around it offers an amazing view towards the Desert des Agriates. The church of Nonza is small but cute, especially nice at sundown.
Walk around, eat something typically Corsican or just enjoy the view from the tower. Nonza Beach is beautiful as seen from the citadel, but swimming is prohibited due to strong currents and high waves.
There are small gift shops as well as charcuteries. Cap Corse wine is also very famous.
Corsican dishes are tasty but expensive. Try them out anyhow.
Corsican wine is a must. A very smart alternative if Birra Corsa, the local beer, not found anywhere else in the world.
You must use the road.
