Route of Water Transport ASDP Paciran - Bawean on the map of Gresik

Night ferry (KMP Gili Iyang) to/from Bawean island (https://www.asdp.id or https://www.indonesiaferry.co.id).

Payment is complicated nowadays (cashless): you need to pay online via transfer (indonesian bank only) or via (indonesian) flashcard (BNI, BRI, Mandiri, ...) The latter you can buy and top up in any Indomaret/Alfamart. An alternative option is to go buy the ticket in the nearest Indomaret/Alfamart and you can pay cash there (at a premium of course). With the payment slip you can enter the port where this paper will be changed to a ticket, with which you can board the ferry
In Paciran harbour there is a free shuttle bus from the terminal to the boat. Be early as the 9pm boat might leave earlier (7pm) if full
