The city bus service, run by ATP Sassari, operates from 07:10 to 20:10. Tickets, on sale at newspaper stands and tobacconist shops, are valid for 90mins and cost €1.20. You can buy tickets on board the bus but you need the right money; €1.70, as the bus driver won’t give you change. Daily bus tickets are also available and cost €3. All tickets need to be stamped as soon as you get on the bus. From 11 Jul to 7 Sep, ATP Sassari also operates a bus service on Asinara Island.
