Twice a month the Pelni shipping lines has a ferry, the KM Bukit Raya that calls on Kota Tarempa (the Archipelago's capital "City") on Siantan Island. You can catch it from the Tanjung Priok harbour in Jakarta, Capital of Indonesia. Sailing times are prone to delays. This boat also delivers almost all the necessary goods to the Islands.
