By train:
Take the Roma-Napoli line and step off at Naples or Pozzuoli Station, then take a boat to Ischia.
By sea:
Ferry boats run from Naples and Pozzuoli, a hydrofoil only from Naples (Mergellina and Beverello piers).
Molo Beverello is Naples' biggest port. Caremar and Lauro Ferries and hydrofoils allow both passengers, cars, bikes and scooters to travel to Ischia, Procida and Capri. Connections with the railway station and airport are provided by bus and taxi.
Mergellina port is the second most important port of the city. It only provides a hydrofoil service, which takes only foot passengers on board. The Snavali trips for Procida and Casamicciola and the Lauro ones for Ischia are frequent. Connections with the station and airport are provided by bus and taxi, as well as the nearby railway station at Mergellina.
The port of Pozzuoli is to be found slightly north of Naples and is fairly well connected to Naples via motorway and city ring road. It provides only a ferry service for Ischia, Procida and Casamicciola. Its geographical position (nearer to Ischia) makes travelling to the islands convenient, both as far as price and the length of the journey are concerned, as well as for those travelling by car.
