Bus services within Sardinia are provided by the Azienda Regionale Sarda Trasporti, which runs the majority of local and long-distance buses.
- ARST also operates a limited network of private servizi ferroviari (narrow-gauge railways), most notably the Trenino Verde.
- In smaller towns and villages there will simply be a fermata (stop) for intercity buses, not always in an immediately apparent location.
- Tickets must usually be bought prior to boarding at stations or designated bars, tabacchi (tobacconists) or newsstands near the bus stop. On some services you can buy tickets on-board but they'll cost slightly extra.
- Timetables are sometimes posted next to the bus stop, but don’t hold your breath.
- Tourist offices in bigger towns can usually provide timetables for their area. Alternatively ask at the bar or newsstand where you buy your ticket.
- Note that while services might be frequent on weekdays, they are cut back drastically on Sunday and holidays. Keep this in mind, as it is easy to get stranded in smaller places, especially on weekends.
