The island’s main bus station is located in Ischia Porto. There are two principal lines: the CS (Circolo Sinistro, or Left Circle), which circles the island anticlockwise, and the CD line (Circolo Destro, or Right Circle), which travels in a clockwise direction, passing through each town and departing every 15 to 30 minutes. Buses pass near all hotels and campgrounds. A single-trip ticket (corsa singola) costs €1.50 (€2 if bought on board). An all-day, multi-use ticket (biglietto giornaliero) costs €4.50 and should be bought from tobacconists.
Taxis and micro-taxis (scooter-engined three-wheelers) are also available.
Car & Scooter
You can do this small island a favour by not bringing your car. If you want to hire a car or a scooter for a day, there are plenty of hire companies. Balestrieri hires out cars and scooters, and it also has mountain bikes (€15 per day). Note that you can’t take a hired vehicle off the island.
If you're hiring a car in high season, parking is going to be a headache. Go for a smart car if you can, which takes up minimal space. There's a small car park at the entrance to Sant’Angelo (two hours €3) and Ischia Porto and Ischia Ponte both have signposted central car parks (€1.50 per hour).
