Ferries connect Indonesia with Singapore and Malaysia. Most connections are between ports in Sumatra (mostly in Riau and Riau Islands provinces) and those in Peninsular Malaysia and Singapore, although there is also a ferry service between Malaysia's Sabah state with East Kalimantan on Borneo. Onward boat connections to Jakarta and other Indonesian islands are available from these ports. See the pages for each city for more details.
