TransNusa Air Services flies daily between Kupang, West Timor and Lembata Island. As always in Indonesia, things can change quickly and frequently so for the latest information about flights check out tiket.com.
The place to start your Solor island hopping adventure depends which way you’re travelling. If you’re travelling eastwards from Flores, there are daily ferry services linking Larantuka with Waiwerang (Adonara Island) and Lewoleba (Lembata Island)
Pelni ships also operate in the area. You can check schedules and prices on the link provided. If you’re island hopping over from the Alor Archipelago and don’t want to wait around for the next Pelni ship, head down to the nearest port and make inquiries about local passenger/car ferries which service the mostly short crossings much more regularly.
