Bus is the cheapest way to travel around Ischia and most of ‘Must visit’ places (Maronti beach, Lacco Ameno shopping street, Sant’Angelo) can be reached by bus. The Ischia buses are frequent enough, they run every 15-20 minutes.
You can buy the tickets at a cigarette shop, newsagents and even bars. You can also buy a ticket directly on the board but you pay a little bit extra in this case. It is also possible to buy 3 days ticket, week or month ticket if necessary.
