Ruta de transporte acuático ASDP Kalabahi-Pulau Pura-Teluk Gurita en el mapa de Kalabahi

There is no fixed ferry port on Pulau Pura at this moment - most likely it arrives on Limarahing (north) or Halugeng (south) (https://www.alorpos.com/2022/01/13/bupati-alor-tentang-dermaga-ferry-bukan-di-limarahing-tapi-di-pura-selatan/)

The ferry schedules from Kupang (Bolok port) and other NTT ports tend to be very flexible (status 2021) with often delays and sometimes cancellations (weather, emergencies). Awkward as only the people in the port seem to know if a boat will go or not that day (Kupang, +62 812 3791 1732, indonesian only!). No official timetables on https://www.asdp.id or https://www.indonesiaferry.co.id, but recent (2022) local newspaper departure times.

Payment was still cash in 2021, but there is a transition ongoing to cashless payment. The cashless payment is complicated: 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.
