To get around in Sardinia, the best way is to use a car. Sardinia has a low population density, with only about 1,500,000 inhabitants over its surface area of 350 x 150 km. Due to this reason, public transportation is not abundant and does not reach all areas, or better said, it does not reach the unique corners worth visiting.
You can reach Sardinia with your own car, departing from the mainland and arriving at one of the main ports that provide ferry services throughout the year. Alternatively, you can rent a car in cities, ports, and airports in Sardinia. It is recommended to always book in advance, especially during the summer period.
Buses - There is no single network in Sardinia with a management system that allows you to understand all regional connections. In addition to ARST (Regional Transport of Sardinia), there are also private companies that provide transportation services, which are widely used by locals and tourists. Depending on where you are or where you need to depart from, it is best to consult the local offerings.
