"Great island in the Bay of Naples"
I really enjoyed Ischia. Since everything is centrally located, I walked wherever I went. You will only need a taxi when you come off the ferry with your luggage and then when you are leaving the island. Busses are readily avaible if you would like to get from one side of town to the other more quickly, or if you choose to visit a neighboring town. Most restaurants and cafes are reasonably priced.
